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 reading, or when the pressure does not rise for a set time after the A/C compressor has been engaged. The signal may be erratic, implausible or stuck. The fault may lie in the wiring, the connectors or the sensor.

Possible causes

Damaged A/C pressure sensor
Signal wire shorted to supply voltage, giving too high a signal
Supply wire to the sensor shorted to battery voltage
Signal wire shorted to ground, giving too low a signal
Break or short to ground in the supply wire
Break in the signal wire or the ground wire

What you can do

1With the engine running and the A/C on, listen for the compressor engaging and check whether cold air comes out
2Check the A/C pressure sensor connector for contact resistance and oxidation
3Check that the A/C system has enough refrigerant and that there is no leak
4Use a multimeter to check that the wires to the A/C pressure sensor have no break or short to ground
5If you have a diagnostic tool, read the A/C pressure in live data with the engine running and check whether the value rises after the compressor engages
6If the fault returns, have a workshop with diagnostic equipment check the pressure sensor and the atmospheric pressure sensor

Symptoms you may notice4

No cooling from the A/C system
The air conditioning does not work
The air conditioning does not cool enough in the front or rear area
The air conditioning cools slowly in the rear area

What the fault can affect3

The A/C pressure sensor is switched off
No replacement value is used for the A/C pressure
The A/C compressor is switched off
