DTC P0217: DECREASED ENGINE PERFORMANCE DUE TO ENGINE OVERHEAT CONDITION

Monitor & Set Conditions

Decreased engine performance due to engine overheat condition is monitored with ignition on and engine running. DTC will set when coolant temperature signal indicates coolant temperature has exceeded the engine protection limit.

Possible Causes

  • ECT Sensor

Testing

Start engine and warm engine to normal operating temperature. Using temperature probe, measure engine temperature near ECT sensor. ECT sensor is located at front of cylinder head, near thermostat housing. Using DRBIII(R) scan tool, read engine coolant temperature. Compare temperature probe reading with scan tool reading. If engine temperature and engine coolant temperature displayed on scan tool are within 10°F of each other, test is complete. If engine temperature and engine coolant temperature displayed on scan tool are not within 10°F of each other, perform DTC P0117: ENGINE COOLANT TEMPERATURE SENSOR VOLTAGE TOO LOW test.
