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 match it to the expected pressure change. The fault may be a signal wire shorted to supply voltage, a faulty ground wire, a damaged sensor, or poor contact.

Possible causes

Signal wire shorted to supply voltage
Ground wire has a break or is shorted to supply voltage
Damaged A/C pressure sensor
Damaged atmospheric pressure sensor
Contact resistance or oxidation in connectors or connections

What you can do

1Start the engine, switch on the A/C, let it run for a while and see whether the code is active
2Check the A/C pressure sensor connector for contact resistance and oxidation
3Use a multimeter to check that the signal wire is not shorted to supply voltage when the ignition is off
4Use a multimeter to check that the ground wire to the sensor has no break and is not shorted to supply voltage
5If you have a diagnostic tool, read the A/C pressure in live data with the A/C on and see whether the value changes as the compressor works
6If the fault returns, have a workshop with diagnostic equipment check the sensor and the atmospheric pressure sensor

Symptoms you may notice3

The air conditioning does not cool enough
The air conditioning cools slowly in the rear area
The air conditioning does not work

What the fault can affect1

The A/C compressor is switched off
