Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected a problem in the primary electrical circuit that drives the fuel pump, often involving the fuel pump relay, wiring, or the pump driver module. Because the fuel pump is essential for delivering gas to the engine, a fault here can cause stalling, hard starting, or a no-start condition. Typical fixes include replacing the fuel pump relay, repairing damaged wiring or connectors, or replacing the fuel pump driver module.
$150 – $700
Varies by vehicle and root cause.
You can usually drive short distances if the car is still running normally, but this code affects fuel delivery, so the engine could stall or fail to start at any time. Avoid long trips and get it checked promptly to avoid being stranded.
Repairs typically range from about $150 to $700. A simple relay or wiring repair is on the lower end, while replacing a fuel pump driver module or the fuel pump itself costs more.
Yes, it can be. Because it involves the fuel pump's power circuit, a failure here can lead to stalling or a no-start condition that leaves you stranded, so it shouldn't be ignored.
The relay is a simple switch that turns the pump on and off, while the driver module precisely controls pump speed in many modern cars. A P0230 can be triggered by a fault in either, so proper diagnosis is important before replacing parts.
