Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected a malfunction in the 'A' fuel metering control of the diesel injection pump, which manages how precisely fuel is delivered. It often points to a failing metering control valve, wiring or connector faults, or a problem inside the injection pump itself. Repairs range from fixing wiring to replacing the metering valve or, in severe cases, the injection pump.
$200 – $1800
Varies by vehicle and root cause.
It's not recommended. This affects fuel delivery in the injection pump, so you risk stalling, being stranded, or further damage. Get it diagnosed before driving more than necessary.
Costs range widely, from about $200 for a wiring or metering valve fix to $1,800 or more if the injection pump itself needs replacement.
Yes. The fuel metering control is central to how the engine runs, and a malfunction can leave you with poor performance, stalling, or a no-start condition. Treat it as a priority.
Not always. Many cases are caused by wiring, connectors, or the metering valve, which are cheaper to fix. A proper diagnosis is needed before assuming the whole pump must be replaced.
