P1217 INFINITI, NISSAN: ENGINE OVER TEMPERATURE
The ECM (Engine Control Module) is the vehicle’s engine function management module. It controls the cooling system and takes into account issues such as the coolant temperature and pressure, vehicle speed, and the A/C (Air Conditioning) ignition signal. This control system consists of 3 steps (High-Low-Off).
If the erratic operation of the cooling fan or other system component is detected, there will be a meaningful increase in the coolant temperature. If the coolant temperature is too high, the engine will have an overheat condition, and the DTC P1217 OBDII code will be set.
