Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected a malfunction in the 'B' fuel metering control of the diesel injection pump, the circuit that manages precise fuel delivery. 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 cause poor performance, stalling, or a no-start condition. Treat it as a priority.
They describe the same type of fault but on different metering control channels, 'B' versus 'A'. The diagnosis and repairs are similar; a technician checks which circuit is reporting the malfunction.
