Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected a lower-than-expected voltage on the 'A' fuel metering control circuit of the diesel injection pump. It commonly points to a short to ground, an open or corroded wire, a failing metering valve, or a connector problem. Repairs usually focus on testing and fixing the circuit wiring and connectors, then replacing the metering valve if needed.
$150 – $1500
Varies by vehicle and root cause.
Only if you have to. A low fuel metering signal can cause stalling or a no-start, so limit driving to getting the car to a shop and have it diagnosed quickly.
Costs range from about $150 for a wiring or connector repair to $1,500 or more if the metering valve or injection pump components must be replaced.
Yes. Because it affects fuel delivery, it can leave you with low power or unable to start. It should be addressed promptly rather than ignored.
A low reading is most often caused by a wire shorted to ground or a high-resistance connection, but a failing metering valve can also be responsible. Testing the circuit pinpoints the cause.
