Still goes into limp mode, even after changing throttle body twice, as well as the battery.
Goes into limp mode - lightning bolt and ESP lights flash. Codes keep saying throttle body, but we have changed that tWiCe, along with the battery and ERG valve. Interestingly, when I check my fuel mileage it goes from the normal range and then jumps to 80+ MPG. Not sure if its related. Does this indicate a PCM problem?
If the lights are still flashing you have a code/codes stored.. Did you get the codes scanned by an OBDii scanner? What is the 4 digit code you are getting?
Oh gosh - I didn't write any codes down, but each time the Chrysler dealership would tell me throttle body. Thats why we kept changing that part. Iv'e had it flashed and upgraded as well, and then was told the voltage was low in the battery so we put a new one in. It seems to be less of a problem when its warm...I'm ready to 'accidentally' roll it off a cliff ;)
It also has to be relearned with a scan tool at the dealer.That is why it keeps going into limp mode. It has to be programmed to the car.
.... it had been relearned as well... Keep the suggestions coming - I appreciate you guys!
Call the dealer and ask for the codes. They will have a record of them. List them for us. We need them.
None of the dealers wrote the codes down. One of then did note the stereo Best Buy installed was pulling on the battery - not sure is that's important. Would a full diagnostic tell me the problem? I can't seem to get anyone to do that - they read the codes and send me on my way.
Yes have that done and then post the codes here and what they found.
Ok - I have another appointment for the diagnostic on Monday - will get back to you after then. Thank you!
let us know
I will - thanks again for your willingness to help :)
OK. I have read up on this a little. Remove your ECM - Clean the connectors - reconnect to ECM - use 2 long wire/zip ties and run each one across the center of each connector down around the computer and pull tight. Reinstall the ECM and tighten bolts very tight. See if it fixes it.
The active codes were U0187 & P 2101 The stored codes were : B1A25 B1A35 P1684 P2110 P0884 C121C B10AC B1601 B1604
BTW tuff4x4 - they refused to try your suggestion :/
P2101 Throttle Actuator Ctrl Motor Circ Range/Perf C121C TORQUE REQUEST SIGNAL DENIED U0187 Lost Comm with Digital Disc Player/Changer Mod A P0884 TCM Power Input Signal Interm P1684 Battery Disconnected in the last 50 Starts P2110 Throttle Actuator Ctrl Sys-Forced Limited RPM B1A25 - invalid key BA135 BAD KEY OR WCM/SKREEM Module
From what it looks like you need to have 2new keys programmed and see if this fixes it.
Interesting. This is the first time a key issue has come up.
That is the BA125 and BA135 codes. If this doesn't take care of it I would have the ECM replaced. This could be expensive but from all these codes first it is saying replace keys and next ECM. This is the engine computer which controls all electrical components to the engine. I have read up on the P2101 and there have been many throttle actuators replaced with no change.
Good info tuff4x4! You've been more helpful than the last 5 visits to Chrysler. The dealership here opened a Customer Care account with Chrysler - after I asked for the # to corporate! Just got the car back... will see how it goes. This time they relearned the throttle body since we changed the battery.
Well, just as I suspected, the car is still up to it's usual thing. I'm in contact with Chrysler hoping to get it on a trailer and taken to another dealership 240 miles away. It's the only option, since the mechanics here know nothing, and aren't willing to listen to suggestions. So frustrating!
I agree. I would insist on them making 2 new keys and programming them.
The next thing would be an ECM.
Update: Got Chrysler tech involved - after two weeks and a long list of a process of eliminations, they put in a new PCM, which seems to have done the trick. But now my new battery is dead,(they discharged it) and the climate control blasts air before the engine is warmed up. *palm to forehead *
I had a cracked factory spark plug when this happened to me
