Pinpoint Test B : P0532, P0533

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.

  1. B1 COMPARE THE PCM (POWERTRAIN CONTROL MODULE) PRESSURE SENSOR (ACP_PRESS) PID (PARAMETER IDENTIFICATION) WITH THE MANIFOLD GAUGE SET READINGS

    • Allow the A/C system to stabilize to the outside ambient temperature.

    • Ignition ON.

    • Using a diagnostic scan tool, view PCM Parameter Identifications (PIDs).

    • With the manifold gauge set connected, compare the pressure readings of the manifold gauge set and the PCM ACP_PRESS PID.

    Are the pressure values of the manifold gauge set and the ACP_PRESS PCM PID within ± 103 kPa (15 psi)? 

    Yes  IGNORE the Diagnostic Trouble Codes (DTCs). REFER to Symptom Charts .
    No  GO to  B2
  2. B2 CHECK THE A/C (AIR CONDITIONING) PRESSURE SENSOR CIRCUITS FOR A SHORT TO VOLTAGE

    • Ignition OFF.

    • Disconnect PCM C175B (2.5L).

    • Disconnect A/C pressure transducer C1260 .

    • Ignition ON.

    • Measure:
      Positive Lead Measurement / Action Negative Lead

      Ground

    Is any voltage present? 

    Yes  REPAIR the circuit.
    No  GO to  B3
  3. B3 CHECK THE A/C (AIR CONDITIONING) PRESSURE SENSOR CIRCUITS FOR A SHORT TO GROUND

    • Ignition OFF.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C1260-1

    Are the resistances greater than 10, 000 ohms? 

    Yes  GO to  B4
    No  REPAIR the circuit.
  4. B4 CHECK THE A/C (AIR CONDITIONING) PRESSURE SENSOR CIRCUITS FOR AN OPEN

    Are the resistances less than 3 ohms? 

    Yes  GO to  B5
    No  REPAIR the circuit.
  5. B5 CHECK THE A/C (AIR CONDITIONING) PRESSURE SENSOR CIRCUITS FOR A SHORT TOGETHER

    Are the resistances greater than 10, 000 ohms? 

    Yes  INSTALL a new A/C pressure transducer. Refer to the appropriate procedure in the Climate Control Systems article. TEST the system for normal operation. If the concern is still present, GO to  B6
    No  REPAIR the circuits.
  6. B6 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect and inspect all PCM electrical connectors (if not previously disconnected).

    • Repair:

      • corrosion (install new connector or terminal - clean module pins)
      • damaged or bent pins - install new terminals or pins
      • pushed-out pins - install new pins as necessary

    • Connect all PCM electrical connectors. Make sure they seat and latch correctly.

    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern,
    No  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
