P0230 OBD-II: Fuel Pump Primary Circuit
P0230 Severity
Should you fix P0230 yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P0230?
The Fuel Pump enables the transfer of fuel from the fuel tank to the fuel injectors in the engine. The Fuel Pump is controlled by the engine computer (PCM) or the Fuel Pump Control Module (most newer vehicles). When the Ignition is turned on, the PCM or Fuel Pump Control Module will activate the fuel pump. If the PCM detects an incorrect signal to or from the fuel pump, it will set code P0230.
