Hva betyr feilkoden?
Although the fault says the signal is missing, the engine control module (ECM) checks whether the signal from the A/C pressure sensor is reasonable, and the fault is set when there is an electrical fault in the sensor or its connections.
Mulige årsaker
- Play, contact resistance or oxidation in the connector
- Damaged A/C pressure sensor
Hva du kan gjøre
- 1Read the fault code, clear it and test drive with the engine at higher revs to see whether it returns
- 2Check that the fuses are intact; their position is in the owner's manual or on the fuse box cover
- 3Check the A/C pressure sensor connector for play, contact resistance and oxidation
- 4If you have a diagnostic tool: read the A/C pressure in live data with the engine running; a value that stays still points to a faulty sensor or connector
- 5If the connector is fault-free: have a workshop fit a new A/C pressure sensor
Symptomer du kan merke1
- The A/C system does not work
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
