Test 1 - Test 3:

Test 4 - Test 8:

SYMPTOM
P0532-A/C PRESSURE SENSOR LOW

WHEN MONITORED
Engine running, A/C is learned, and the AC Clutch Relay energized.

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

POSSIBLE CAUSES
- A/C pressure sensor voltage below 0.6 of a volt
- (F856) 5-volt supply circuit open
- (F856) 5-volt supply circuit shorted to ground
- A/C pressure sensor
- (C18) A/C pressure signal circuit shorted to ground
- (C18) A/C pressure signal circuit shorted to the (K900) sensor ground circuit
- PCM
