Check gauges light comes on, oil pressure fluctuates, then goes to 0


Asked by Jan 28, 2015 at 05:15 PM about the 2007 Dodge Ram 1500 SLT Quad Cab

Question type: Maintenance & Repair

This started last week, first my check gauges light came on while driving down the highway.  I pulled over, checked the oil, which was fine, then it ran fine.  This problem continued until yesterday when the check gauges light stayed on and the oil pressure stayed at 0, even though oil was fine.  Today, the truck would not start at all; tried to turn over, but never would, then died completely. Any ideas?

are there any leaks

There is a minor coolant leak; gasket needs to be replaced, however, no oil leaks.

Is the battery dead or bad?

The battery was fine until a little while ago. My truck has a remote start feature. Had planned on going in to town and used the key fob to start it and warm it up as usual, not thinking about the ongoing oil pressure issue. When I went out to get going, the truck hadn't started, so I tried to start it manually and discovered that it wouldn't even turn over. I am thinking that trying to start drained the battery?


you probably drained the battery trying to start it. the original problem sounds like the oil pressure sending unit or the oil pump. cross your fingers and hope for the sending unit.

the remote start didn't work due to the fact that you have 0 psi on the oil pressure gauge the pcm monitors this and most likely set a code ...// with an active code it disengages the remote start feature until the active code is fixed ...// hopefully its a pressure sending unit and you didn't seize the engine

drop your oil pan. The oil pick up line for your oil pump a lot of times will get clogged with carbon, sludge, and pieces of paper from old oil filters. just drop your oil pan and clean out from in front of the screen. Not hard and fixes your oil pressure problem.

Thank you all so much for your responses and advice. I picked up a sending unit, will get it in this weekend. Crossing fingers it does the trick!

What happened ? Did the sending unit do the trick ? I have same problem


Chk guages means all gauges . Voltage /temp/oil/ etc etc . Anyone of the gages could cause that warning light . Make sure you havevthe proper voltage ,,that the temp Guage isnt too high or too cold . (Possibly not working ) . Look for random fluctuations in the gauges as well .could be an intermittent issue you just haven't noticed .

My 07 ram 1500 did the same thing -- check gauge came on !! Couldn't figure it out til I saw battery gauge too low- anyway turned out to be both battery and alternator were both bad !! Different from check engine -


Same thing with me... so, what "exactly" fixed the problem or stopped the "Check Gauges" light from coming on as the Oil Tac fell back to zero?
