What it means
The first fuel shutoff valve is commanded on but does not open. Fuel cannot reach the engine via this path.
At a glance
- Usually lights the check-engine light
How it works
Fuel shutoff valve A controls fuel flow through its supply path when commanded by the control module. This code indicates valve A is commanded open but fails to open as expected, which can restrict fuel delivery and prevent the engine from starting or running properly.
Common causes
Most likely first.
- Valve seized closed by debris
- Solenoid loses force from coil aging
- Carbon or debris buildup preventing free movement
Symptoms
- Check-engine light
- Engine may crank without starting
- Engine may stall or lose power
How to diagnose it
- Record freeze-frame data and check for related fuel-pressure or starting codes before clearing anything.
- Inspect fuel shutoff valve A, its connector, and nearby wiring for damage, corrosion, or loose connections.
- Use a scan tool, if supported, to command valve A open and check whether the module reports a response.
- Test the valve A control circuit and solenoid for continuity and shorts according to the manufacturer's specification.
- If electrical checks pass, determine whether debris or a sticking mechanism is keeping valve A closed.
Common fixes
- Reconnect or repair damaged wiring at fuel shutoff valve A.
- Clean debris from valve A if it is obstructing movement.
- Replace the valve A solenoid if its coil fails the manufacturer's test.
- Replace fuel shutoff valve A if it remains seized closed.
Can I keep driving?
If the engine cranks without starting, or stalls or loses power, do not rely on the vehicle for a trip; arrange a safe place to stop and have it checked. A restricted fuel path can cause sudden stalling and leave the vehicle unable to restart.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
