P02EC

DTC P02EC, sometimes indicated as P02EC00 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 system - high air flow detected.

This code is set when the PCM detects that the diesel intake air flow is high. There are several possible causes for this code, including a defective intake air flow sensor, a clogged air filter, or a defective PCM.
If this code is set, the first thing you should do is check the air filter to make sure it is not clogged. If the air filter is clogged, clean or replace it. If the air filter is not clogged, test the intake air flow sensor to see if it is defective. If the sensor is defective, replace it. If the sensor is not defective, test the PCM to see if it is defective. If the PCM is defective, replace it.
