Hva betyr feilkoden?
The fault is intermittent, meaning it has occurred but does not necessarily remain present right now. The engine control module (ECM) measures intake manifold pressure with a sensor and sets the fault when the sensor circuit is shorted to ground or voltage, or when it has a break.
Mulige årsaker
- Damaged intake manifold pressure sensor
- Open circuit in the signal wire
- Signal wire shorted to ground
- Signal wire shorted to voltage
Hva du kan gjøre
- 1Read the fault code, clear it and test drive to see whether it returns
- 2Move and flex the pressure sensor wiring with the ignition on and see whether the fault code or the signal changes
- 3Check the pressure sensor connector for contact resistance and oxidation
- 4Check the wire to the pressure sensor for breaks, pinch damage and chafing
- 5If you have a diagnostic tool: follow the pressure sensor value in live data while you move the wiring; if the value jumps or disappears, the wiring is most likely the cause
- 6If the wiring is fine: have a workshop check the pressure sensor
Symptomer du kan merke1
- Engine warning lamp comes on
Hva feilen kan påvirke1
- A value from the MAF sensor is used instead
