What P0006 means
The fuel shutoff valve is a solenoid valve that opens or blocks the fuel supply. On diesel engines it is usually closed without current, so that the engine stops reliably when switched off. The engine control module energises it to let fuel flow and monitors its control circuit continuously. P0006 means voltage or current in the control circuit is below the expected range, typically because of a short to ground; depending on the output stage an open circuit can also show up this way. The valve is then not energised correctly, which can prevent starting or make the engine stall.
P0006 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0006
- Check engine light on
- Hard starting or no start
- Engine stalls
Common causes of P0006
- Most likelyShort to ground in the harness
- PossibleShorted turns in the valve coil
- PossibleCorroded connector
- Less likelyOutput driver in the engine control module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0006 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 06 | The exact fault in that area. |
What to do next
- Note P0006 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0006
What does P0006 mean?
P0006 means "Fuel Shutoff Valve A Control Circuit Low". The fuel shutoff valve is a solenoid valve that opens or blocks the fuel supply. It is a generic code, so it means the same on every make.
Is it safe to drive with P0006?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0006 fail an emissions test?
Yes, it can. P0006 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0006 to fix?
Difficulty: medium. A typical repair takes 0.5 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0006 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
