Re: Newbie with error code question...!!! Please Help...!!!

Whats up Andrew...? Just got back from the dealership and I'm gonna give you the scoop from the tech below as documented by the Service Associate:

"Diagnosed CE Light. Found Heater Circuit Wire was shorted to ground. There is possibility that the shorted wire created damage to the PCM. Tech also noticed a "NEW" transmission, probably remanufactured, had been recently installed. The wiring containing the shorted wire was ran over the top of the transmission. Did no further diagnosis, but there is a possibility the shorted wire was pinched during the installation of the new transmission."

Is it possible that the short would appear somewhere else in this circuit that the tech isnt exposing to me in order for them to do the labor? Also, where is this wiring found coming from (the PCM I assume) and going to, in order for me to diagnose the exact location of the short myself rather than pay them the 2 hours labor that they're asking ($80 per hour)? Thanks for any advice that you can provide BTW ! One more quick question... does the PCM need to be reset after the fix? Easiest way to do so? Or can the codes just simply be erased via an OBD scanner? Thanks yet AGAIN !

Crestwood1001 is an unknown quantity at this point
Get under there and follow the wires from the o2 sensors and see which one tracks over the tranny

Re: Newbie with error code question...!!! Please Help...!!!

Followed harness from Bank 1 o2 sensor and it IS NOT crimped anywhere up to the main harness at a couple threads that talked about an issue with the main harness rubbing against a bolt on the backside of the upper part of the engine near the PCM on Bank 2 side...anyone else heard of this problem...harness is pulled so tight that I can't turn the wiring over to see if this is the issue or it possible to test the PCM alone to see if it, indeed, is what's causing the entire issue...? Thanks in advance...
