About P0992

P0992 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 P0992 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

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 P0992 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 P0992 is set when the Transmission Control Module (TCM) detects an abnormal voltage reading from the Transmission Fluid Pressure Sensor/Switch 'F' Circuit. This occurs when the sensor's signal is outside of the expected range, either too high or too low, for a specified period of time. This condition suggests a malfunction in the transmission fluid pressure sensor/switch or its circuitry.
