    Corrosion of the ECT sensor coupler caused by moisture entry.

    Replacement of the sensor and coupler rectifies the complaint.
    Repair Method
    1. Remove the coupler from the ECT2 sensor. See diagram below for component locations
    2. Inspect the ECT2 sensor for corrosion. A judgement will need to be made regarding the amount of corrosion on the sensor. If the sensor pins are excessively corroded the sensor will need to be replaced.

    3. Inspect the ECT2 sensor coupler for corrosion. If any corrosion is evident you will need to replace the harness section.
