Does anyone know or would someone be willing the check their voltage at the Throttle Control Motor wires with key in ON position? My TCM does not respond, Car will idle in limp mode with it unplugged, plug it back in and it stalls. Have tested continuity on every wire I can find to eliminate a bad or broken wire, have checked all wires to ground to see if there is a short. Scanner shows gas pedal is functioning, changed TPS, no change, and this is a new TCM. Codes all reference TCM. Found it strange that there is voltage on both wires to the TCM, which could be the issue, but I don't have a wiring diagram to verify grounding of TCM.
Any help is greatly appreciated before I spend a chunk of money replacing the PCM.
