P0252

DTC P0252, sometimes indicated as P025200 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 injection pump fuel metering control a range/performance (cam/rotor/injector).

The DTC P0252 is a code that is generated by the engine control module (ECM) when it detects that the injection pump fuel metering control A range/performance (cam/rotor/injector) is not within the manufacturer's specifications. There are several potential causes of this code, including a defective injection pump, a defective camshaft, a defective rotor, or a defective injector.
The best way to diagnose the cause of this code is to use a diagnostic scanner to read the live data from the engine. This will allow you to see which component is not performing within the manufacturer's specifications. If the code is being caused by a defective component, the scanner will also be able to provide information on how to fix the issue.
