About P0806

P0806 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 P0806 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; 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 P0806 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 P0806 is set when the vehicle's powertrain control module (PCM) or transmission control module (TCM) detects that the input signal from the clutch position sensor falls outside the expected range or exhibits performance issues. This sensor monitors the position of the clutch pedal, providing crucial data for vehicles with manual or automated manual transmissions. The code is often triggered by a signal that is inconsistent with the clutch pedal's actual position or by a signal that fluctuates beyond normal operating parameters.
