Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC P0217: Notes
The coolant temperature telltale on the instrument panel cluster (IPC) has the ability to illuminate as a result of an engine over temperature condition. The engine control module (ECM) or powertrain control module (PCM) will send a message to the IPC over the class 2 link to turn the coolant temperature telltale ON, if the engine coolant temperature (ECT) exceeds the temperature calibration value listed under Conditions for Setting the DTC.
