Hva betyr feilkoden?
The engine control module monitors the A/C pressure sensor and sets the fault when it registers a fault in the control of the sensor. The cause is a signal wire shorted to ground. The driver is not normally aware of the fault.
Mulige årsaker
- Signal wire short-circuited to ground
Hva du kan gjøre
- 1Read out the fault code, erase it and road-test to see whether it returns
- 2Switch off the ignition and unplug the A/C pressure sensor connector. Check it for looseness, contact resistance and oxidation
- 3Use a multimeter to check that the signal wire from the sensor is not shorted to ground
- 4Look for chafed wires near the sensor, especially where they may have touched metal
- 5If the fault remains, have a workshop with diagnostic equipment check and, if needed, replace the A/C pressure sensor
Symptomer du kan merke1
- No noticeable symptoms for the driver
