Symptom: P0532-A/C PRESSURE SENSOR LOW When Monitored and Set Condition: 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 TEST ACTION APPLICABILITY 1 NOTE: Ensure the A/C refrigerant System is properly charged per the t, read the A/C Pressure Sensor voltage. Is the voltage below 0.6 of a volt? All Yes → Go To 2 No → Refer to the INTERMITTENT CONDITION symptom in the Driveability category. 2 Turn the ignition off. All Yes → Go To 3 No → Go To 7 213 DRIVEABILITY - NGC |
