4.27 DTC P0961 – Line Pressure Control
Solenoid System Performance
DTC Description
This diagnostic procedure supports DTC P0961 Line Pressure Control (PC) Solenoid System Performance.
Circuit 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 current to the solenoid. The applied current can vary from 0.1 – 1.1 A. Low current,
0.1 A, indicates high line pressure. High current, 1.1 A, indicates low line pressure. The duty cycle of the PC solenoid
valve is expressed as a percentage of energised on time. Zero percent indicates zero on time, non-energised, or no
current flow. Approximately 60 percent at idle indicates maximum on time, energised, or high current flow. The TCM
determines the appropriate line pressure for a given load by comparing the throttle position, the engine speed and other
inputs.
W hen 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.
Refer to 2 W iring Diagrams and Connector Chart to aid in diagnosis.
Conditions for Running the DTC
• The system voltage is 8 – 18 V.
• The engine is running.
Conditions for Setting the DTC
The PC solenoid valve duty cycle reaches its high limit, approximately 95 percent, or low limit, approximately 2 percent.
Action Taken When the DTC Sets
• The TCM does not request the engine control module (ECM) to illuminate the MIL.
