Pinpoint Test C : Pinpoint Test

WARNING: This page is about a different variant/trim than selected.
  1. WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in serious personal injury.

  2. C1 CARRY OUT INSPECTION AND VERIFICATION

    Were any concerns found? 

    Yes  REPAIR as needed.
    No  GO to  C2

  3. C2 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) P0125 OR P0128

    • Ignition ON.

    • Using a scan tool, perform the PCM self-test.

    Is DTC P0125 or P0128 present? 

    Yes  GO to  C3
    No  The cooling system is operational. If an inoperative temperature gauge is suspected, CHECK the temperature gauge operation. REFER to: Instrumentation, Message Center and Warning Chimes . If an inoperative climate control system is suspected, CHECK the climate control system operation. For Dual Automatic Temperature Control REFER to: Climate Control System - Vehicles With: Dual Automatic Temperature Control (DATC) . For Electronic Manual Temperature control (EMTC) REFER to: Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) . If any other Diagnostic Trouble Codes (DTCs) are retrieved,

  4. C3 CHECK THE COOLANT LEVEL

    NOTE: Allow the engine to cool before checking the coolant expansion tank.

    • Visually check the engine coolant level in the coolant expansion tank

    Is the engine coolant level within specification? 

    Yes  GO to  C4
    No  GO to Pinpoint Test A 

  5. C4 CHECK THE ECT (ENGINE COOLANT TEMPERATURE) SENSOR OPERATION

    • Using a scan tool, view PCM PIDs.

    • Monitor the ECT temperature PID.

    • Using an Infrared temperature gun measure and record the temperature of the coolant outlet housing at the rear of the cylinder head near the ECT sensor.

    Is the temperature reading similar to the ECT PID value? 

    Yes  INSTALL a new thermostat. REFER to: Thermostat Housing .
    No  INSTALL a new ECT sensor. REFER to: Engine Coolant Temperature (ECT) Sensor .
