About P0997

P0997 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 P0997 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 P0997 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 fault code P0997 is set when the Transmission Control Module (TCM) detects an issue with the performance or range of the Shift Solenoid 'F' Control Circuit. This typically indicates that the solenoid's operation is outside of the expected parameters, either not responding correctly to the TCM's commands or operating in a manner that is inconsistent with its designed performance. This can be due to electrical issues within the solenoid circuit or mechanical problems affecting the solenoid's operation.
