About P0995

P0995 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 P0995 is stored, the module has detected a signal or supply voltage higher than the expected operating range; and 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 P0995 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 P0995 is set when the Transmission Control Module (TCM) detects that the signal from the Transmission Fluid Pressure Sensor/Switch 'F' Circuit is higher than the expected range. This high voltage condition suggests that the fluid pressure in the transmission is exceeding the normal operating parameters. Such a scenario typically indicates an electrical or hydraulic malfunction within the transmission system.
