DTC P0217: Notes
The coolant temperature telltale on the instrument panel (I/P) cluster has the ability to illuminate as a result of an engine over temperature condition. The engine control module (ECM) will send a message to the I/P cluster 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.
