P0230 to P0233: fuel pump circuits
The fuel pump's primary circuit has a fault, or its secondary circuit reads low, high or intermittent.

Can you keep driving?Only as far as the workshopWhat does P0230 mean?
The electric fuel pump in the tank is switched by a relay or a pump control module, and the engine computer watches the circuit. These codes do not measure fuel pressure; they say the electrical supply to the pump, or the feedback from it, is wrong. With no supply the engine will not start; with an intermittent one it can cut out while driving.
What causes P0230?
- A failed fuel pump relay
- A blown fuel pump fuse
- A corroded connector on top of the tank or a damaged wire
- A worn pump drawing too much current, or a failed pump control module
What to check first for P0230
- Listen for the pump running for a second or two when the ignition is switched on
- Check the fuel pump fuse and swap the relay with an identical one
- Inspect the pump connector and the wiring to the tank
- Have the pump's current draw and the voltage at the pump measured
Can you drive with P0230?
Drive only as far as you must. The engine can cut out without warning, in traffic or at speed, and may not restart; if it has already cut out once, have the car towed.
In states with an OBD-II emissions inspection, a car with the check engine light on fails the test until the fault is fixed.

These are the generic meanings every manufacturer shares. Each brand adds its own detail, so your car's handbook, its service information and a qualified mechanic have the last word. OdoKeep has no connection with any manufacturer, and the app does not read codes from the car.
