I have a 2004 3.5L Chrysler Pacifica and I have this error (P0202 - Cylinder 2 Injector Circuit Malfunction). The mecanic changed the plugs, the injector and the induction coil but the error is still there. The engine is not running smootly-but this not happening all the time- especially when is very cold. The mecanic said the TCM-transmission control module. I'd like to know where is this TCM because I need the code in order to buy the piece. Has anybody had this problem? Thank you

 

The transmission is causing a "INJECTOR MALFUNCTION". I think your mechanic is malfunctionning. Get a second opinion or go to the dealer for a proper diagnostic.
