SYMPTOM
P0532-A/C PRESSURE SENSOR LOW

WHEN MONITORED
The engine running. The A/C relay energized.

SET CONDITION
The A/C pressure sensor signal voltage at the PCM goes below 0.58 volts for 2.6 seconds. One Trip Fault.

POSSIBLE CAUSES
- A/C pressure sensor voltage below 0.6 volts
- (K7) 5 volt supply circuit shorted to ground
- (K7) 5 volt supply circuit open
- A/C pressure sensor internal failure
- (C18) A/C pressure signal circuit shorted to ground
- (C18) A/C pressure signal circuit shorted to (K4) sensor ground circuit
- PCM (K7) 5 volt supply circuit
- PCM A/C pressure sensor signal
