P0961 — Pressure Control Solenoid A Control Circuit Range/Performance

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0961

P0961 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0961 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0961 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P0961 fault code is activated when the control module detects a range or performance issue in the control circuit of Pressure Control Solenoid A. This solenoid is vital in the automatic transmission, where it regulates hydraulic pressure to assist in gear shifting and the operation of the torque converter clutch. A range or performance issue in this circuit suggests that the operation of the solenoid or its control circuit is either not within the specified parameters set by the manufacturer or is not functioning efficiently. Potential causes include a malfunctioning solenoid, wiring issue...
