What does this fault code mean?

The ECM monitors the pressure in the A/C system. The code is set when the high-side sensor gives a faulty signal and the module cannot reconcile it with the pressure change it expects. The fault lies in wiring with a break or a short, a damaged sensor, or poor contact.

Possible causes

Break in the supply voltage wire
Supply voltage wire shorted to ground
Break in the signal wire
Signal wire shorted to ground
Contact resistance or oxidation in connectors or connections
Damaged A/C pressure sensor

What you can do

1Check that the fuses are intact
2Check the pressure sensor connector for contact resistance and oxidation
3Use a multimeter to check that the supply to the sensor has no break and is not shorted to ground
4Use a multimeter to check that the signal wire has no break and is not shorted to ground
5If you have a diagnostic tool, read the A/C pressure in live data with the engine running and see whether the value changes as the system works
6If the fault returns, have a workshop with diagnostic equipment check the pressure sensor

Symptoms you may notice4

The air conditioning is not cold enough in the rear area
The air conditioning cools slowly in the rear area
The air conditioning is not cold enough in the front area
The air conditioning does not work

What the fault can affect2

The A/C pressure sensor is switched off
The A/C compressor is switched off

General guidance for car owners. Diagnosis on the car can point to a different cause.
