OBD II Fault Code

  • OBD II P02EA

    OBD-II Code Decreased engine performance is defined as a Diesel Intake Air Flow Position Sensor Circuit Intermittent/Erratic

    The volume of air going through the intake is controlled by the Intake Airflow Control Valve on the throttle body. The Intake Airflow Position Sensor tells the engine control module (PCM) the position of the Diesel Intake Airflow Control Valve. When the PCM detects a problem with this sensor or the circuit for the sensor, it will set code P02EA. This sensor is replaced as a unit with the throttle body and is not serviceable separately.
