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 voltage. The driver is not normally aware of the fault.
Mulige årsaker
- Signal wire short-circuited to voltage
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. Use a multimeter to check that the signal wire is not shorted to voltage
- 3Look for wires that may have rubbed against a live part
- 4If 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
