P02E2 OBD-II: Diesel Intake Air Flow Control Circuit Low
P02E2 Severity
Should you fix P02E2 yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P02E2?
The volume of air going through the intake is controlled by the Intake Airflow Control Valve on the throttle body. If the engine control module (PCM) detects an implausible signal to or from the Intake Airflow Control Valve, the PCM will set code P02E2.Failure of the Intake Airflow Control Valve may require replacement of the throttle body assembly, as it is not always serviceable separately.
