If the P0217 code is present and there are no coolant leaks, start by servicing the coolant system and replacing the thermostat to resolve the problem.
Check the 'Possible Causes' listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
The cost to diagnose the P0217 code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
Engine coolant temperature is excessively high under normal engine speed.
The Engine Control Module (ECM) monitors the engine coolant temperature with the engine running. The P0217 code is set when the temperature is higher than normal even and there is no heavy load to the engine.
