    Description of DTC code P0222 Generic

    The diagnostic code P0222 OBDII is set when the PCM (Powertrain Control Module) has detected a signal voltage from the TPS (Throttle Position Sensor) that is below the predetermined range. Depending on the vehicle model, the lower limit is between 0.17 and 0.20 volts.

    Generally, a voltage deviation greater than 10% of the reference voltage will cause the code to be stored and the Check Engine light to illuminate.

    Symptoms of fault code P0222 Generic

    • The MIL (engine malfunction) light comes on.
    • The engine may not start.
    • Acceleration problems.
    • Power loss.
    • Black smoke expelled by the exhaust

    Causes of OBD2 P0222 Generic

    When setting the error code P0222 OBD2, it is due to the following reasons:

    • The Acceleration Position Sensor (TPS) installation is not correct.
    • The TPS sensor may be shorted to the ground.
    • Perhaps the TPS sensor is defective

    Possible solutions of the DTC code P0222 Generic

    When solving the DTC code P0222 OBDII, you must take into account:

    • Check the Throttle Position Sensor (TPS). Check its connector, as well as the sensor-related cables. If any wires are worn or burned, repair or replace them.
    • Check the voltage of the TPS sensor, then consult the specifications. If the voltage is not within specifications or is too low, change the sensor.
    • If you recently changed the Throttle Position Sensor, it may be incorrectly adjusted. You should consult the installation instructions for correct alignment.
    • If no symptoms are present, the problem may be intermittent. Clear the code and if it comes back, make sure the cable system is in good working condition. Change the TPS sensor if necessary.
