P0253

DTC P0253, sometimes indicated as P025300 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 low (cam/rotor/injector).

This code is set when the PCM detects that the fuel injection pump fuel metering control A is low. This code is usually caused by a malfunctioning fuel injection pump or a low fuel pressure condition.
If this code is present, inspect the fuel injection pump and the fuel pressure. If the fuel injection pump is defective, replace it. If the fuel pressure is low, check the fuel pressure regulator and the fuel lines for leaks.
