P0006

Fuel Shutoff Valve A Control Circuit Low

Q: Is it safe to drive with P0006?

Not really — because this valve controls fuel to the engine, the fault can leave you stranded with a stall or no-start. Treat it as urgent.

Q: Can I just clear P0006?

You can, but if the circuit fault is still present it returns quickly — and the engine may not restart. Fix the cause first.

Fuel system Generic OBD-II High

What it means

P0006 means the engine computer detected low voltage — a short to ground or an open — in the control circuit for fuel shutoff valve 'A'. This valve, common on diesel and some fuel-injected engines, controls whether fuel reaches the engine. When its circuit faults the engine may be hard to start, stall, or refuse to run.

High

Can I keep driving? Risky — the fuel shutoff valve gates fuel to the engine, so a circuit fault can cause hard starting, stalling, or a no-start. Get it diagnosed before you're stranded.

How to diagnose & fix

Work through it in order

Read freeze-frame data and check the valve connector for a low or grounded control signal.
Inspect the wiring between the ECM and the shutoff valve for shorts to ground, chafing, or corrosion.
Measure the solenoid's resistance against spec; replace the valve if it's out of range or open.
Confirm the valve gets power and a clean ground, and repair wiring as needed.
If wiring and valve test good, suspect the ECM control driver. Clear and re-test.
