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.

Likely causes

Clutch position sensor faulty (pedal or actuator)
Connector or harness open, corroded or shorted
Transmission module software (Nissan)
Control unit internal fault (Ford DPS6: clutch motor driver)

Symptoms

  • Check engine lamp on
  • Idle stop disabled ('Idle Stop System Fault')
  • Jerky driving or harsh clutch engagement (dual clutch)
