Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected low voltage in the secondary side of the fuel pump circuit, which carries power to the pump itself. The result can be insufficient fuel pressure, leading to stalling, hard starting, or poor performance. Typical fixes include repairing wiring and connectors, replacing the fuel pump relay or driver module, or replacing the fuel pump.
$150 – $750
Varies by vehicle and root cause.
Short trips are usually okay if the car still runs well, but low voltage to the fuel pump can cause stalling or a no-start. Avoid long drives and get it inspected soon to be safe.
Repairs generally run from about $150 to $750. Fixing wiring or a relay is cheaper, while replacing the fuel pump or driver module costs more.
Yes, it can be. Low voltage in the fuel pump circuit can reduce fuel pressure and cause stalling or a no-start, so it should be addressed without long delays.
It means the voltage on the power side of the fuel pump circuit is reading lower than expected. This often points to high resistance from corroded wiring or connectors, but a weak relay or pump can also be to blame.
