Hi everyone,
I recently purchased a 2002 Town and Country 3.3lt engine. i drove for about 2 weeks and it drove fine. I went to start it and it would barely idle. Had it towed, put a code reader on it and it brought up code P0122 ( Throttle sensor voltage low). Replaced sensor-no dice. I put a multimeter on the 5 v wire and I got 3 volts. However, I also have 3 volts on any of the sensors that have the 5 volt reference wire, but no error codes with those. Is this the issue, or is there some other issue that I need to look in to. Any help would be appreciated.

John

 

possible other sensor bring down the 5v or the PCM is not putting teh full5v out.

 

The idea of a forum is to help one other with problems, suggestions, information and to help people save some time and money. For the 14 year mechanic who has all the experience and no tack for helping others, I would say to him, join a website where you can charge people for your information and experience, that is if you are a professional technician and mechanic. Because you comment didn't help the man in need.
