Function Explanation (DTC Detection Outline)

Repeatability Verification Procedure

1.  Warm up the engine to allow the engine coolant temperature to reach 50—95 °C {122—203 °F}.

Note

•  The difference between PIDs ENG_COOL_VLV_POS_ACT and ENG_COOL_VLV_POS_COMD displayed the engine coolant control valve opening angle must be within 2 °.

•  Match the engine coolant temperature in the recorded freeze frame data/snapshot data, the vehicle speed, and engine speed values to the best extent possible while driving the vehicle.

2.  Try to reproduce the malfunction by driving the vehicle for 5 min based on the values in the freeze frame data/snapshot data.

Troubleshooting Diagnostic Procedure

―  Perform an inspection of the connectors and wiring harnesses between the coolant control valve and the PCM.

―  Perform a unit inspection of the coolant control valve.

―  Perform a unit inspection of the coolant control valve position sensor.

―  Verify that the primary malfunction is resolved and there are no other malfunctions.
