I have a Dodge Caliber R/T with just over 300 miles on it. A few nights ago the check engine light came on and does not go out. I checked engine fluids, gascap, etc, and the light is still on. I performed the ignition engine code check and the vehicle is not reporting any codes. I then disconnected the battery for five minutes or so with the hope that it might reset the computer. The light remained on after this still. The car is driving fine and the manual indicates the light indicates an issue with the engine or transmission as reported by the OBD 2 computer and there is not cause for immediate alarm unless the engine light is flashing.

I live in Germany and have an appointment tomorrow with the local Chrysler dealer, but was wondering if anyone can offer clues as to what may be causing this given there are no codes and the car is otherwise driving fine.

Thanks!

 

Hi,

Sorry can't help you with the light problem, but I would like to know how you did the ignition engine code check?? Might come in handy later!

 

Put the key in the ignition and cycle the ignition from the "accessory" postion to the "on" position three times and leave it in the "on" position (ACC-ON-ACC-ON-ACC-ON -- The "on" position is just short of turning the engine over.) Do this in rapid succession, I think within 3 seconds. Once you have done this, look in the right instrument cluster and you will see the display change to dashes. If you have any codes, they will show up here. When the test is complete, it will indicate "-Done-". Go to this link in these forums for the codes: https://dodgeforum.com/m_126008/tm.htm

I had to do this a few times to get it to work... I think I was doing it too slow.

 

Thanks, I will try that, it's something which will always be handy.

 

Our's came on a short time after purchase as well. Was a bad O2 sensor.

 

On the way in this morning to my local German Chrysler Dealer to have the light checked, I stopped to put gas in the car and, lo and behold, the light went out. I went to the dealer anyways. Though the ignition check for codes didn't reveal any, they could pull up the code that had initiated the light on sequence. Turns out, it was in fact my gas cap, though I had checked it already. Lesson learned here, however, was that when I checked the cap previously, I only turned the cap a few times to make sure it was on and didn't remove it and replace it.

In any case, mystery solved!
