Was bedeutet der Fehlercode?
The engine control module (ECM) receives an A/C pressure sensor signal below the sensor's normal operating range. The air conditioning does not work while the fault is present. The causes are the sensor's wiring, its connector, or the sensor itself.
Mögliche Ursachen
- Open circuit in the sensor supply voltage
- Open circuit in the sensor ground lead
- Damaged A/C pressure sensor
Was Sie tun können
- 1Read and note the code, clear it and road test with the A/C switched on
- 2Check that the A/C pressure sensor connector is fully seated and free from corrosion or raised contact resistance
- 3Follow the cable between the sensor and the engine control module, looking for breaks, chafing or loose clips
- 4With a multimeter, confirm that the supply and ground leads to the sensor are continuous and not broken
- 5If you have a diagnostic tool, read the A/C pressure in live data with the A/C on and see whether the value is unrealistically low
- 6If the fault remains after these checks, have a workshop test or replace the sensor
Symptome, die Sie bemerken können1
- The A/C system does not work
