The 'Clutch Position Sensor A' family (P0805 circuit to P0809, P080A not learned) means different parts by vehicle generation. GM used P0806–P080A until model year 2018 for the analog clutch pedal sensor of its manual cars, then the newer pedal sensor codes P08A8 ff; Saab's 2012 9-3 does the same. Ford's DPS6 dual clutch uses the family for the electric motor of clutch A. P0808 means the signal is too high. GM sets it above 96 % of the 5 V reference with the same 200 of 250 samples of 12.5 ms, type A with the MIL after one trip; Saab's 2012 9-3 above 4.8 V for longer than 0.6 s, with cruise control switched off. Typical causes are an open sensor ground or a signal wire shorted to the 5 V reference or battery voltage.

Likely causes

Sensor ground open
Signal shorted to 5 V or battery voltage
Pedal sensor faulty
Moisture or corrosion in the connector

Symptoms

  • Check engine lamp on
  • Cruise control not working
