P0981 — Shift Solenoid D Control Circuit Range/Performance

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

About P0981

P0981 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 P0981 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 P0981 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 P0981 fault code is set when the control module detects a range or performance issue in the control circuit of Shift Solenoid D. This solenoid is crucial in the functioning of automatic transmissions, where it regulates the flow of hydraulic fluid to engage or disengage gears. A range or performance issue suggests that the operation of Shift Solenoid D or its control circuit is not within the specified parameters set by the manufacturer or is not functioning efficiently. Causes could include a malfunctioning solenoid, wiring problems, or issues within the Transmission Control Module (TCM) ...
