Diagnostic Aids

Possible causes of DTC P0217:

• Cooling fan(s) inoperative.
• Engine cooling system overheated condition (thermostat, low engine coolant etc.).
• Radiator or condenser air flow restricted.
• Air dam missing or loose.
• Overload due to trailer towing.
• ECT sensor leaking engine coolant into ECT sensor harness connector causing elevated temperatures.
• ECT sensor skewed.

The PCM will command the A/C relay Off if the temperature of the engine coolant is greater than 248°F (120°C) to protect the engine and transaxle.
