P02D2

Cylinder 4 Fuel Injector Offset Learning At Min Limit

DTC P02D2, sometimes indicated as P02D200 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 cylinder 4 fuel injector offset learning at min limit.

The purpose of cylinder 4 fuel injector offset learning is to determine the offset between the commanded injection quantity and the actual injection quantity. If the actual injection quantity is less than the commanded injection quantity, the offset learning value is increased. If the actual injection quantity is greater than the commanded injection quantity, the offset learning value is decreased. The DTC sets if the offset learning value at the minimum limit is reached.
There are several possible causes for this DTC, including a mechanical failure of the fuel injector, a wiring failure, or a problem with the ECM. If the DTC is set, the best way to resolve it is to troubleshoot the system and find the root cause of the problem.
