Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected a higher-than-expected voltage on the 'A' fuel metering control circuit of the diesel injection pump. It commonly points to a wire shorted to power, a faulty metering valve, or a corroded connector creating an abnormal signal. Repairs usually involve testing and fixing the wiring and connectors, then replacing the metering valve if it has failed.
$150 – $1500
Varies by vehicle and root cause.
Only short distances if needed. A high metering signal can cause stalling or power loss, so it's safest to drive only to a shop and have it checked soon.
Repairs range from around $150 for wiring or connector fixes to $1,500 or more if the metering valve or pump components need replacement.
Yes. It affects how much fuel reaches the engine, so it can cause poor performance or a no-start. It's best handled promptly rather than left to worsen.
A high reading is most often caused by a wire shorted to power or a corroded connector, though a failing metering valve can also trigger it. Circuit testing confirms the real cause.
