Circuit / System Description
The pressure control (PC) solenoid valve is an electronic device that regulates transmission line pressure based on the current flow through its coil winding. The magnetic field produced by the coil moves the solenoid\'s internal valve which varies pressure to the pressure regulator valve. The transmission control module (TCM) controls the PC solenoid valve by applying a varying amount of amperage to the solenoid. The applied amperage can vary from 0.1-1.1?amps. Low amperage, 0.1?amp, indicates high line pressure. High amperage, 1.1?amps, indicates low line pressure. The duty cycle of the PC solenoid valve is expressed as a percentage of energized ON time. Zero?percent indicates zero ON time, non-energized, or no current flow. Approximately 60?percent at idle indicates maximum ON time, energized, or high current flow. The TCM determines the appropriate line pressure for a given load by comparing the throttle position sensor voltage, the engine speed and other inputs.
When the TCM detects a continuous open or short to ground in the PC solenoid valve circuit, then DTC?P0961 sets. DTC?P0961 is a type?C?DTC.
