Hva betyr feilkoden?
Pressure in the A/C system is watched by the engine control module (ECM). The code is set when the pressure does not rise as expected on the high-pressure side when the compressor starts, and the signal from the sensor is too low. The fault can be checked when the A/C is switched on.
Mulige årsaker
- Leak in the A/C system
- Damaged pressure sensor
- Damaged A/C compressor
Hva du kan gjøre
- 1Check that the fuses are intact. Their location is in the owner's manual or on the fuse box cover.
- 2Switch on the air conditioning at maximum cooling and check that the compressor engages. Listen for a click when it starts.
- 3With the ignition off, check the connector at the A/C pressure sensor for looseness, contact resistance and corrosion.
- 4If you have a diagnostic tool, read the pressure from the A/C pressure sensor with the A/C on, and check that it rises when the compressor runs.
- 5If the compressor engages but the cooling is absent, or if the fault remains, have a workshop check the A/C system for leaks and the compressor.
Symptomer du kan merke1
- The air conditioning does not work
