Fault code

P0230: Fuel pump primary circuit

What does it mean?

System: Powertrain (engine and transmission)
Subsystem: Fuel and air metering (injectors)
Type of code: Generic code: means the same on every make.

How urgent?

High

Do not drive further than you need to: carrying on can damage the engine, the catalyst or other parts. If the engine light is flashing, stop safely as soon as you can.

Possible causes

Fuel pump or fuel filter
Pressure regulator or rail pressure sensor
Injector (clogged, leaking or electrical fault)
Wiring or connector

Tip: don’t just clear the code. Clearing a code doesn’t fix the cause. It often comes back, and the stored data that helps us find the cause is then gone.
