P0217 - ENGINE OVER TEMPERATURE

Table Of Contents

    Description of DTC code P0217 Generic

    Most vehicles are equipped with the ECT (Engine Coolant Temperature) sensor. This sensor sends a signal to the PCM (Powertrain Control Module) and indicates a voltage reading. This reading is the vehicle’s temperature value.

    The DTC P0217 OBD2 means that the engine is in an overheat condition. Usually, the temperature is above 240°F, but it may vary according to the cooling system manufacturer.

    The overheat light turns on to prevent any damage to the engine, so it is recommended that the engine be shut down as soon as possible.

    Symptoms of fault code P0217 Generic

    • The Check Engine light turns on the dashboard.
    • Coolant may be ejected from the reservoir.
    • There may be a loss of engine power.
    • The air conditioning may not work.

    Causes of OBD2 P0217 Generic

    The fault code P0217 indicates one or more of the following problems:

    • The coolant level may be below the required level because of a leak in the cooling system.
    • The radiator or cooling system may be clogged by some elements.
    • The thermostat may be stuck or faulty.
    • The cooling fan may not be working.
    • The water pump or pump impeller may be faulty.

    Possible solutions of the DTC code P0217 Generic

    Steps for fixing the diagnostic code P0217:

    • Check the coolant level with the engine cold. If you notice that the level is low, it may be due to a leak in the system. Make any necessary repairs. Then, you should replace the thermostat, which is usually damaged after the engine overheats. After replacing the thermostat, refill the cooling system. Start the engine and check that it does not overheat.
    • If there are no leaks but the coolant level is low, it is because the cooling system protects itself from overpressure by expelling coolant through the radiator cap after the engine overheats.
    • If the coolant level is normal, check the radiator and A/C condenser for any obstructions that stop airflow. You might remove the radiator for a thorough inspection. Make sure all the plastic panels that carry the airflow are in the right place. Also, check that the cooling fans are working properly with your scanner. Make any necessary repairs. Replace the radiator if necessary.
    • If there are no problems but the vehicle continues to overheat, check if the hose above the radiator is hot. If it is, it means that the coolant is flowing correctly. If it is not hot, it indicates that the water pump impeller may be faulty. Inspect the water pump, if you can't find any problems with it, the thermostat may be the cause of the problem. Replace it.
    • In case it is still overheating, after making the above-mentioned repairs, probably combustion gases are leaking into the cooling system. You should test for gas leakage in the combustion system in the cooling system. Repair if you find such leaks.
    • You can change a coolant temperature transmitter.
