Circuit Description

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

Ignition voltage is provided to the torque converter clutch pulse width modulation (TCC PWM) solenoid valve. The TCM controls the solenoid with a negative duty cycle in order to control application and release of the TCC. When the solenoid is commanded OFF, the TCM senses high voltage. When the solenoid is commanded ON, the TCM senses low voltage.

DTC P2763 sets if the TCM detects a voltage that is outside of the calibration limits. DTC P2763 is a type B DTC.
