P0005
Stop drivingThe engine computer (PCM) detects an open circuit in the fuel shutoff valve 'A' control circuit, meaning it cannot properly control the fuel flow to the engine.
Code P0005 means your engine's fuel shutoff valve control circuit has an open fault. Common causes: Faulty fuel shutoff valve (60%), wiring issues (30%). Drivability: No, stop driving. Repair cost: $50-$350 DIY, $150-$800 professional.
Can I Drive With P0005?
No, stop driving
Immediate repair needed
Stop driving immediately if: Engine will not start, engine stalls, significant power loss, any burning smell.
Symptoms of P0005
- 1Engine will not start
- 2Engine stalls shortly after starting
- 3Engine runs very rough or misfires
- 4Check Engine Light is on
Common Causes of P0005
Parts most likely causing this code, ranked by probability
The fuel shutoff valve itself can fail internally, leading to an open circuit or preventing proper fuel flow control.
60% of P0005 cases are fixed by replacing this part
Damaged, corroded, or disconnected wiring or a faulty connector to the fuel shutoff valve creates an open circuit.
30% of P0005 cases are fixed by repairing wiring or connectors
A rare internal fault within the engine computer's driver circuit for the fuel shutoff valve can cause this code.
10% of P0005 cases are fixed by replacing the ECM/PCM
Check These First (Before Buying Parts)
- Visually inspect the fuel shutoff valve's electrical connector for any signs of damage, corrosion, or loose pins.
- Trace the wiring harness leading to the valve for any obvious cuts, chafing, or signs of rodent damage.
How to Diagnose P0005
- 1Visually inspect the fuel shutoff valve and its electrical connector for any obvious damage, corrosion, or loose connections.
- 2Using a multimeter, check for continuity and proper resistance across the fuel shutoff valve's terminals (refer to service manual specifications).
- 3With the ignition on, check for proper voltage and ground signals at the fuel shutoff valve connector from the PCM.
- 4If the valve and wiring test good, further diagnosis of the PCM may be necessary, but this is less common.

Frequently Asked Questions
What does P0005 mean?
P0005 indicates that your vehicle's engine computer (PCM) has detected an open circuit in the control circuit for the fuel shutoff valve 'A'. This means the PCM cannot properly send or receive electrical signals to control the fuel flow to the engine.
Can I drive with P0005?
No, stop driving. This code points to a critical issue with your engine's fuel delivery system. Driving with this code can lead to the engine stalling unexpectedly, not starting at all, or potentially dangerous uncontrolled fuel delivery issues. Immediate repair is necessary.
Will P0005 clear itself?
No, P0005 will not clear itself. This code indicates a hard electrical fault or a failed component that requires diagnosis and repair. The Check Engine Light will remain on until the underlying issue is fixed and the code is cleared, either by the PCM after several drive cycles or with a scan tool.
How do I fix P0005 myself?
Start by visually inspecting the fuel shutoff valve and its wiring connector for damage or corrosion. If the wiring looks good, you will need a multimeter to test the resistance of the fuel shutoff valve and check for proper voltage and ground at its connector. If the valve is faulty, you can replace it. If the wiring is damaged, you can repair it.
How much does it cost to fix P0005?
The cost to fix P0005 varies. If you do it yourself, expect to pay $50-$350 for a new fuel shutoff valve or wiring repair parts. If you take it to a professional shop, the repair will cost $150-$800, including diagnostic time and parts. If the rare PCM failure is the cause, costs can be significantly higher.
P0005 keeps coming back - why?
If P0005 keeps returning, it means the initial repair did not fully address the root cause. This often happens if a wiring issue was overlooked, the replacement fuel shutoff valve was also faulty, or the less common PCM fault was not diagnosed. A thorough electrical diagnosis is essential to pinpoint the exact problem.
Will P0005 fail emissions/smog test?
Yes, P0005 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on for any reason is an automatic failure in most jurisdictions. Furthermore, a fault in the fuel shutoff valve can directly impact engine emissions.
What's the difference between P0005 and P0006?
P0005 indicates an 'open circuit' in the fuel shutoff valve 'A' control circuit, meaning the PCM detects no electrical signal. P0006 indicates a 'low' circuit condition, meaning the PCM detects a voltage signal that is too low. Both point to issues with the same circuit but describe different electrical fault types.
P0005 on Ford F-150?
P0005 is not a code with a common, specific pattern for Ford F-150s or any particular vehicle. When it appears on an F-150, the diagnostic steps remain the same: inspect wiring, test the fuel shutoff valve, and check PCM signals. The fuel shutoff valve location may vary by engine type and year.
Questions to Ask Your Mechanic
Did you check the resistance of the fuel shutoff valve itself?
Good answer: Yes, I measured the resistance and compared it to factory specifications. It was either open or out of range, indicating an internal fault.
What did you find when you inspected the wiring and connector to the fuel shutoff valve?
Good answer: I found corrosion in the connector pins, or a section of wire was chafed and broken, causing the open circuit.

Cost of Waiting
Ignoring P0005 means your engine will not start or will stall unexpectedly, leaving you stranded. It can also lead to dangerous uncontrolled fuel delivery if the valve fails in an open position, potentially causing engine damage or fire. A $50-$350 repair now prevents being stranded or facing more severe consequences.
While You're In There...
While not directly related to the electrical fault, if you are working on the fuel system, it is a good time to replace the fuel filter if it's accessible and due for maintenance, preventing future fuel delivery issues.
If you are disconnecting fuel lines to access the shutoff valve, replacing any associated gaskets or O-rings prevents fuel leaks.
Tools You'll Need
- OBD-II Scan Tool
- Multimeter
- Wire Strippers/Crimpers (if wiring repair needed)
- Basic Hand Tools (sockets, wrenches)
- Wiring Diagrams (vehicle-specific)
P0005 is a serious code because it affects engine operation, but it often points to a straightforward electrical fault or a failed fuel shutoff valve. Once diagnosed and repaired, your engine's fuel system will function correctly.

Your Next Steps
Step 1: Perform a thorough visual inspection of the fuel shutoff valve and its wiring harness and connector. Look for any obvious damage, corrosion, or loose connections.
Step 2: If the visual inspection doesn't reveal the issue, use a multimeter to test the resistance of the fuel shutoff valve itself. Compare your reading to the vehicle's service manual specifications. Then, check for proper voltage and ground signals at the valve's connector from the PCM.
Step 3: Based on your electrical tests, you'll likely need to replace the fuel shutoff valve if it's faulty, or repair the wiring/connector if that's the issue. If both test good, further advanced PCM diagnosis may be required.
