Circuit Description
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The torque converter clutch (TCC) pressure control (PC) solenoid valve regulates modulator pressure, based on the current flow from the powertrain control module (PCM). The PCM outputs a varying amount of amperage, as necessary for TCC application, and the TCC PC solenoid valve supplies oil pressure proportional to the current to the TCC PC solenoid valve and the lock-up timing valve. The PCM monitors the current flowing through the solenoid valve and performs feedback control.
If the current is not within the specified range for a given duty output, DTC P2763 sets. DTC P2763 is a type A DTC.
