P0805Clutch Position Sensor A Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- The J2012 family 'Clutch Position Sensor A' (P0805 circuit, P0806 range/performance, P0807 low, P0808 high, P0809 intermittent, P080A not learned) covers the position of a clutch – the pedal of a manual gearbox, the clutch actuator of an automated or dual-clutch gearbox, or a clutch inside an automatic. P0805 is the general circuit fault. Uses differ: Nissan's 2022 Pathfinder with its nine-speed automatic stores it in the transmission module, lights the MIL and disables idle stop ('Idle Stop System Fault'), fixed with new software. Ford's DPS6 dual-clutch gearbox uses it for the module-internal chip that drives the clutch A motor, so a control unit fault rather than an outside sensor. GM reads its clutch pedal sensor under P0806–P0808 only.
- What you may notice
- Check engine lamp on
- Idle stop disabled ('Idle Stop System Fault')
- Jerky driving or harsh clutch engagement (dual clutch)
- Likely causes
- LikelyClutch position sensor faulty (pedal or actuator)
- PossibleConnector or harness open, corroded or shorted
- PossibleTransmission module software (Nissan)
- PossibleControl unit internal fault (Ford DPS6: clutch motor driver)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
