About P0807

P0807 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 P0807 is stored, the module has detected a signal or supply voltage lower 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 P0807 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

Fault code P0807 is set when the vehicle's powertrain control module (PCM) or transmission control module (TCM) detects a lower than expected voltage from the clutch position sensor circuit. This condition typically indicates an electrical issue within the circuit, such as a short to ground or an open circuit. The clutch position sensor plays a critical role in vehicles with manual or automated manual transmissions by providing information about the clutch pedal's position.
