What does this fault code mean?
The engine control module carries out overall checks of the system's components. The code is set when it has found a fault in the A/C pressure sensor system but cannot decide exactly what the fault is. The code has no fault-tracing of its own and is dealt with through the other engine control module codes for the A/C system.
Possible causes
- A fault in the A/C system that the control module cannot link to a single component
What you can do
- 1Read out all fault codes in the engine control module and deal with the A/C system codes first
- 2Erase this code once the other codes have been dealt with, and road-test with the A/C on to see whether it returns
- 3If you have a diagnostic tool, check in live data that the A/C pressure sensor value changes when A/C is switched on and off
- 4If the code comes back, have a workshop with diagnostic equipment look further into the A/C system
Symptoms you may notice1
- No noticeable symptoms for the driver
