Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected an intermittent (on-and-off) fault in the 'A' fuel metering control circuit of the diesel injection pump. Intermittent codes are usually caused by loose or corroded connectors, chafed wiring, or a metering valve that's beginning to fail. Repairs focus on finding and fixing the unstable connection, often by inspecting and securing wiring and connectors before replacing parts.
$120 – $1200
Varies by vehicle and root cause.
You often can for a while, but the fault may become constant without warning and leave you stranded. It's best to get it checked before that happens.
Because it's often a wiring or connector issue, repairs can be as low as $120, but can reach $1,200 or more if the metering valve or pump parts need replacing.
It can be. Even if symptoms are occasional now, intermittent fuel metering faults tend to get worse and can lead to stalling or a no-start. Don't put off diagnosis.
Because the fault isn't always present, it can be tricky to catch during testing. Technicians often wiggle-test wiring and connectors while monitoring data to reproduce the glitch.
