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 clutch pressure control (PC) solenoid valve 2 regulates modulator pressure based on the current flow from the powertrain control module (PCM). The PCM outputs varying amounts of amperage, as necessary for gear change, and the clutch PC solenoid valve 2 supplies oil pressure, proportional to the current, to the clutch PC solenoid valve 2 and the reverse clutch PC valve. The PCM monitors the current flowing through the solenoid and performs feedback control.
If the current is not within the specified range for a given duty output, a fault is detected and DTC P0966 sets. DTC P0966 is a type A DTC.
