MOFLON MZ048-P0230-P0205

Diagnostic trouble code (DTC) P0230 stands for “Fuel Pump Primary Circuit.” This code sets when the powertrain control module (PCM) detects a signal to or from the fuel pump that does not match the expected values.

The fuel pump makes it possible for the fuel to travel from the fuel tank to the fuel injectors in the engine. It’s controlled by the engine computer or the PCM, but in newer vehicles, it’s often controlled by the fuel pump control module (FPCM).

When the ignition is turned on, the PCM or FPCM will activate the fuel pump. If the PCM or FPCM receives a voltage that does not match the expected values, it will set the P0230 code.
