I have the same problem on Dodge 2002 Ram 1500. I replaced the sensor. It was broke, however It did not fix the problem.

Brad was right for me! I have a 2004 1500 4.7 5speed with 108,000miles. My speedo was possessed, fluctuating while parked and the odometer was advancing, also while parked. The ABS, Check engine, and Brake lights were all on. I first bought a new CPU. wasn't the problem and took it back, tried a new Gauge cluster from a friends truck, still nothing. Disconnected the radio and A/C wires from the dash and nothing. Also checked all fuses, all were good. I read on here (and my last resort before taking it in) that it could be the rear speed sensor so I found a new one on Ebay for $25.00 and figured well for that price what the hell. Got it in the mail yesterday and installed it in less then 15min today. Turned the key and the demons are all gone! The lights are out and everything is back to normal! Saved over $1000.00 from what the idiot mechanic was going to charge doing everything I just did on my own. Thanks Brad and to the people on these posts!

Hey Brad . I have the same problem. Replaced the oss and rear sensors and the problem remains.In addition to the above conditions my tranny feels fucked up as well . Am I right in thinking the bad spedo signal is screwing up the tourque converter function? Or is this a seperate issue? Any info would be greatly appreated. thanks in advance Pete

can you tell me the part # and where it is located??? I just replaced the speed sensor on the left side of tranny and they still don't work....

Same Thing happened to me already. Dog chewed my output sensor wires. Tranny went to shit. Rebuilt it and now Speedometer quits again and I'm getting the first sings of Transmission Failure!!! NO Codes Just Brake and ABS lights not check engine. I just replaced the output sensor and still nothing. Can anyone tell me anything about this apparently horrible trans??? Tyler

Before you go thru what I did for 5 months. Check the ignition switch, it is what was wrong with my 03 5.7. No speedo most of the waning lights in dash, no ac/heat, no odometer.

Problem: I have a 2004 Dodge Ram 1500 5.7 L HEMI. My ABS and Parking Brake lights were illuminated, and my speedometer needle would "bounce". Also when sitting at a stop sign or just sitting idle, the engine would stall, and often times stop running. Solution: After long research on this problem, I decided to dig in and try to find the problem myself. I replaced the Rear ABS Sensor ($35) that's located on top of the rear differential. Still no fix. I then unplugged the ABS Controller (or Module) that's located directly behind the battery (You should see the metal brake lines running into the top of it.) When I unplugged it, I noticed LOTS of moisture in the plug. Using an air hose, I blew out the water and let it dry good. When I plugged it back in, and hooked the negative battery terminal back up THE PROBLEM WAS SOLVED!! Simple fix. Hope this helps.

I wish i could read this add before. I have also this problem in my 1999 dodge ram 1500 4x4 sport i took it to the mechanic they changed the speed sensor in the transmission but the problem still there so know I will buy the sensor in the differential is the ABS sensor hope this solve the problem. thanks for all the good comments.

Check all your 15 amp fuses, make sure none are burnt and that all are in place even the spare ones, had to do this to my 2007 Dodge Ram 1500 and all is well now.

I have a 2007 dodge ram. A couple of weeks ago my cigarette lighter went out. So then I finally looked at the fuses and it was out. I replaced the cigarette lighter fuse with the spare. Then after that the ABS and Brake light came on. Also my speedometer did not work. Today i finally had a chance to by extra fuses. So I replace the spare fuse and everything went away. That is a really wierd setup but problem fixed.

I also have a 2007 Dodge Ram 5.7 liter engine. When I replaced the trailer park lamp fuse ( cavity 15) with a Spare Fuse ( cavity 30). My ABS light, check engine light and speedometer stopped working. Not only was the manual wrong, the fuse location stamp inside the Integrated Power Module was wrong !!! It could have been a really costly mistake by the manufacturer, Don't think that just because it's marked as a "spare" it may not be.

I have a 2002 Dodge Ram 1500, ABS, brake, check engine, no speedometer and no fuel gage... I started with P0500 code that suggest changing the VSS, changed it and the ABS sensor, still no luck. Transmission is also experiencing late shifts. I am really frustrated, any ideas??

110 out of 110 people think this is helpful.

I just wanted to reiterate what BigDodge718 stated. I also have a 2004 Dodge Ram 1500 4.7L 2WD that exhibited the same symptoms. I also first swapped out the rear ABS speed sensor and nothing changed. I then removed the connector to the ABS controller and I could POUR out the water in the connector. Once I dried it out with compressed air (great idea BigDodge718), I reconnected it and it worked great! I'd almost suggest checking the connector before buying and trying the speed sensor - it might save you $30-35. Good luck!

Speedometer erratic. ABS and brake lights on. I don't even have ABS! Changed the sensor in the transmission, and the one on the differential. No luck. Now experiencing late shifts also. I also cleaned battery cables.

I have a 2001 Dodge Ram 3500 Van and about 9 months ago the speedo stopped working, the AC stopped working (blowing cold and vent blowing on HIGH), the ABS and Brake light came on steady and the check engine light came on. It also pulsed or surged at times when driving. I had it hooked up to a computer and the code read P0500 "no vehicle signal". So I replaced the rear speed sensor and it did not fix the problem. The fuses were all fine. I had it in a garage for almost a month as they checked wires and hooked computers to it to no avail. I started reading posts and saw that it could have been the ABS Module. So I found a great company online (ModuleMaster) out of Moscow, ID and they rebuilt my module for $130 and sent it back to me. When I got it back I re-installed it and all of the problems when completely away. This lasted for about 9 months. Sad to say the same symptoms are back and so I called ModuleMaster and told them what it was doing and they told me that they would gladly look at it again (since it was under a 5 year warranty). I sent it off to them and they re-worked it and when I got it back the paperwork said they "replaced wheel speed signal conditioning chip and reflow soldered everything again". I reinstalled it and voila everything worked again with no problems ...until I put it into drive. Once in drive the ABS light, brake light, AC stopped working, etc. Back to square one. I am at a total loss as to what is causing this problem. Can anyone help me with this? I don't really feel like taking it to the dealer as it will cost around $1,000 if it needs a new ABS module and I am not totally convinced that's the problem. It seems like the second it hit R (reverse) as I was putting it into drive everything started up again. Of course this might not mean anything at all. Also, at times when this has happened in the past the reverse lights don't work. Something wacky is definitely going on and I would like to get to the bottom of it. PLEASE ADVISE! Thanks! In case it helps, I have also had times when the AC/Heat switch would not work (blow at any speed) and I replaced a small part that goes into the blower housing. Not sure if that could be related to the problem or not?...

I have an 01 dodge ram 1500 automatic. It has abs, traction control and parking break lights are on all the time. we replaced the rear speed sensor and they are still lighting up. As well when we drive in the rain a new symptom has cropped up all idiot lights come on then the speedo goes down then the rpm gague and finally all the pressure gagues go down and the No Bus indicator comes on while these gagues and lights are going wonky. The main computer module has been replaced within the last year as well. While all this is going on the truck continues to drive and function normally. Any ideas?

For me it was the plug behind the battery, I figured out if you park in a driveway don't point the truck down the driveway. It rained last night and even though there's a weather strip it will travel around it and drip towards that plug from the side of the weatherstrip. Usually it's got to be a pretty heavy rain but either way I want to protect it. I plan to buy some foam with sticky backing from Walmart or Ben Franklin for less than a buck and wrap it enough but not completely. I just want enough protection to run the water away from the plug area to prevent this from happening again. Do not completely cover entire unit !!! Do not put silicone or some kind of sealer on plug to prevent leaking in, another no no. As I said if you park with the nose down it will get water in the plug from heavy rain even though there's a weatherstrip, I have an 03 truck with good weatherstrip and it does run down the side of strip and down the side behind the battery and it can travel or slash on the plug. It was hard to unplug for me. I had to lift up the red tab to unlock it then when i figured it was free it wasn't. you need to squeeze the back of the plug and you will feel it break free or squeeze in, then pull the plug out. Hope this helps.

We have a new to us 1999 V6 Dakota and just replaced the VSS sensor and the rear wheel ABS sensor. This fixed the issues.... ABS, check engine, and brake idiot lights no longer on, speedometer and odometer now working once again! (Previously the speedometer and odometer did not function, some mentioned there's did have intermittent fluctuations, ours did not operate at all.) Also this allowed the cruise control to work along with the automatic door lock safety feature allowing the doors to lock after reaching a certain speed. Have also been told if cruise control didn't work it could be due to a vacuum leak, luckily ours was fixed by aforementioned sensors.

Ok... so I have read thru here and I have similar problem. 07 Ram 1500 4x4 ext cab.5.7 Hemi. Attempted to install double din, but wiring wasn't a match. ordered new harness, but screen wouldn't light up (Had sound tho). Blew a fuse and replaced it. put original radio back in. Now I have light cluster lit up, no speedometer or Odometer, and it won't engage the front axel when in 4 wheel drive. I can here it switch at the transfer case and 4x4 light just flashes and never goes solid. I can spin the rear wheels but front doesn't engage.

why wount my speedometer work on my 2001 dodge ram 1500 ive aleady chaged the transmission speed sensor?

23 out of 23 people think this is helpful.

I recently purchased a 99' Ram 1500 and it has the same issue as described here. ABS, Brake and speedo not working properly (it bounces). None of these lights go away and or the speedo always bounces to about 50-60mph, then it seems to be intermittently bouncy. I got a check engine light appear while driving to work last week and stopped to have the code checked- it said the ABS sensor. Yesterday I purchased a rear ABS sensor for about 25$ and installed it hoping that I would get the easy fix like some of the others here but no. The check engine light is gone and there's no codes now but the lights and bouncy speedo remain. I have been researching the issue for about 2 weeks now and found it is a few things that can cause this. A faulty ABS sensor is one of them ofcourse but there is also the ABS module under the hood- a common moisture issue there. Then there is the ignition switch at the key. Those 3 things range from pretty easy 15 min install to hours and hours of tracking down a bad connection. the rear ABS= 15mins. A new ignition switch is 2-3hrs installed. Tracking down faulty wires and wiring harrnesses... who knows = days. So far I found out my issue is not with the rear ABS speed sensor. Today I removed the ABS module from under the hood and everything seemed to be just fine, no corroded wires or water coming out. I did hear that if both or more lights are on, it is more likely to have an electrical issue versus a sensor issue. If the rear ABS sensor doesn't fix these issues continue to check the other system components for connection corrosion or moisture problems. I'm still on the hunt.

most of these problems are wiring issues bad ground loop to abs module, possible shorting in wiring probably the wiring harness behind your brake pedals (look up and to the left) have a peek can't hurt these problems manifest from Speedo malfunction heat a/c malfunction abs malfunction and after the abs is fixed it takes approx 50 ign sequences to reset the pcm any way before replacing sensors check your pigtails and test voltages why fix what isn't your problem. I'm gonna find a link and post it soon its for a wiring diagram and proper voltage signals good luck

diagnostic trouble code - dtc check engine light - cel foremost what state are you in and is the truck California emissions what drive train is in your truck

2 out of 2 people think this is helpful.

second is your trucks speedometer functioning properly or is it bouncing around or unresponsive as per the thermostat are you running hot or cold is it stuck open are you over heating

I'm so California and speedometer Bounces around and sometimes Unresponsive

5 out of 5 people think this is helpful.

Not over heating at all and truck runs great which is why I'm confused why the smog failed

1 out of 1 people think this is helpful.

the speedometer is either the speed sensor on the rear differential or a wiring issue probably a bad ground if you look in your truck at the brake pedal you'll see a wire harness I have to find the link for it but I found the wiring schematics for dodge trucks the speedometer controlled by a set of sensors that go awry time to time but these trucks are very sensitive to moisture as well I'd start with the connections to your sensors check the harness to the abs module for moisture make sure connections are tight and depending how handy you are check the rear sensor for a voltage signal if you have no abs issues than its more than likely the sensor on the rear diff or a minor wiring issue lastly what was the reading from your exhaust probe

2 out of 2 people think this is helpful.

for your smog test make sure there's no check engine lights or trouble codes make sure you have a clean airfilter run some high octane fuel and I've read that an additive can help like blue sky clean air but I'm apprehensive about additives your exhaust is running a bit too rich so high octane helps with upper end lubrication for the valve train and combusts more complete the clean airfilter will ensure proper fuel to air ratios can be provided to the engine not to mention without air you can't achieve combustion so long as you have no trouble codes these few things should get you where you need to be if you want specifics about your speedometer problem I can send you some walk throughs and the thermostat I don't understand the issue there unless there's failure with the unit did they specify why its bad


I have 04 dodge ram 5.7 I have a problem for about 6 month's my truck dont speed more then 5 miles I put the machine and said pedal position sensor I replace and nothing the mechanic said is the trottle and nothing I check fuses and still tge same and a light red come on my dash anyone now whats that

2002 Ram 1500 here with ABS module issues...the plug itself caught fire and melted. Can I get just the pigtail and maybe a new module or am I going to have to pay 3.2 million dollars for a COMPLETE wiring harness. Also, wasn't there a recall on this issue???

2000 1500 4 wheel drive, no speedometer, ABS and Brake light on. I replaced the ABS rear speed sensor and it fixed the problem. My only advice is to lower the spare tire and you can get to the sensor much easier, also it took quite a bit of time to get the old unit off, had to keep turning it and working it with channel locks because you don't want to break it off inside the differential. Be sure and put a little grease on the new unit o ring and it will slip in much easier.

had same issues on 07 2500 5.9 4x4 warning lights ,abs, no speedo door windows not working . I cleaned battery terminals good, put 10 amp fuses in empty spots in fuse block replaced the trailer light fuse which was blown now all works.


My water pump went out last week, and then I had the same problem it was water in connector.

All right so here it goes again. I have a 99 dodge ram 1500 4x4 5.9 I'm having the same issues. It started slow like the lights will come on randomly as I was driving. 8 months later they just stay on. I've cleaned all connectors, sanded and regrounded every ground, replaced battery terminals, taken the cluster out and cleaned the connectors on the back (only 2 of them). Also I've taken the connectors of the computer on the front and cleaned the shit out of them. I've notice that when I take the I.o.d fuse out, everything works except the radio, interior lights and the carco lamp on the back. Besides that she drives normal. Do I need my I.o.d fuse in. I can by pass the radio to make it work. Any advice. Pls help

same problem on 99 dakota replace rear sensor no help front senspor no help im thinlking its in the wiring


Mines comes and go now. Idk what it is. @kimber, try you crank position sensor. Hope it works


I have a similar problem with my 07 dodge caliber (abs and brake light ding on, radio turns off, speedometer stops working) but only for a fraction of a second. it has happened three or four times randomly while I am driving in the past month. But now my car will not start! It will not be jumped either. No power whatsoever (lights, doors, nothing). Are these issues related?! I am going to look into water in the abs controller plug, but none of these posts mention a complete loss of power. Help!

1 out of 1 people think this is helpful.

Having same problem, no speedo, fuel gauge, no dash lights except turn signals and high beam light, tranny staying in second, with is going on. Checked the fuses, they're all good. Somebody please tell me where to start. I'm a chick and I know some about vehicles. But have absolutely no idea where to start on this one.

im having similar issues with my 08 charger, we can be driving and after a while the rear breaks will engage and release like i just punched the breaks, and the esp/bas lights light up, tc and speedo go nuts then the trans acts like its in limp mode. could a wheel speed sensor cause this?

So, if you tried everything above and nothing worked, try this: Check the fuse labeled Anti Lock Brakes (#27 on my dakota slt 3.9 4x4) with a light tester. Have the ignition key turned on. See if you get NO LIGHT on both terminals. That was the problem with mine. There is no power to my entire 3rd row of fuses that includes :heated seat, anti lock brake, and reverse lights etc. To fix it, I "jumped" power from the row above at fuse #6 or 7 it was a blank "not used fuse" that only gives power when the ignition is on. (tested with light) I simply stripped both ends of a short wire and jumped it from top terminal to top terminal. Probelm solved...got my speedo, odom back, and brake n abs light off. This was all after changing sensors, tearing apart the distribution center, and tracing wires for 2 weeks. good luck!

I have a 2008 dodge ram diesel 1500 standard when I get up to 60 miles it want go no faster what could be wrong
