Engine idling
A/C on.
Check whether the fault is permanent or intermittent. Read off the signal from the air conditioning (A/C) pressure sensor.

Check that the signal is within its permitted range and that the pressure increases in the air conditioning (A/C) system when the air conditioning (A/C) compressor engages.

The fault is permanent if the signal is incorrect. The fault is intermittent if the signal is correct.
