P02E5
Diesel Intake Air Flow Control Stuck Closed
DTC P02E5, sometimes indicated as P02E500 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing diesel intake air flow control stuck closed.
This code is set when the PCM detects that the diesel intake air flow control valve is stuck closed. This can be caused by a number of things, including a bad valve, a dirty or blocked valve, or a wiring problem.
If this code is set, the first thing you should do is check the wiring to the diesel intake air flow control valve to make sure it is properly connected and not damaged. If the wiring is good, then you should check the valve itself for damage or blockage. If the valve is damaged or blocked, it will need to be replaced.
