    P0217-DECREASED ENGINE PERFORMANCE DUE TO ENGINE OVERHEAT CONDITION

    POSSIBLE CAUSES

    • ECT SENSOR
    • OTHER DTC'S
    • MECHANICAL FAILURE

    DIAGNOSTIC PROCEDURE

    NOTE: Refer to VERIFICATION TESTS for appropriate verification test procedures.

    1. With the DRBIII®, read DTCs. Are other Cooling system DTCs present?
      Yes --> Trouble shoot the other DTCs first
      No --> Go To 2
    2. Allow the engine to reach normal operating temperature. Use a temperature probe and measure the engine temperature near the ECT Sensor. With the DRBIII®, read the Engine Temperature. Compare the temperature probe reading with the DRBIII® reading. Are the readings within 10°F of each other?
      Yes --> Repair the cause of mechanical failure
      No --> Replace the coolant temp sensor.
