P0007
Stop drivingThe engine's computer detects a high voltage condition in the control circuit for the fuel shutoff valve 'A'. This valve controls fuel flow to the engine.
Code P0007 means your fuel shutoff valve control circuit has a high voltage issue. Common causes: Wiring damage (60%), faulty fuel shutoff valve (35%). Drivability: No, stop driving. Repair cost: $50-$400 DIY, $150-$800 professional.
Can I Drive With P0007?
No, stop driving
Immediate repair needed
Stop driving immediately if: Engine stalls, engine won't start, significant power loss
Symptoms of P0007
- 1Engine cranks but will not start
- 2Engine stalls unexpectedly while driving
- 3Significant loss of engine power
- 4Check Engine Light is on
Common Causes of P0007
Parts most likely causing this code, ranked by probability
A short to voltage, corrosion, or an open circuit in the wiring leading to the fuel shutoff valve causes the ECM to detect a high voltage.
60% of P0007 cases are fixed by repairing wiring or connectors
The solenoid inside the fuel shutoff valve can fail internally, causing an electrical fault that results in a high voltage reading in its control circuit.
35% of P0007 cases are fixed by replacing the fuel shutoff valve
A rare internal failure of the ECM's driver circuit for the fuel shutoff valve can cause it to send or receive incorrect voltage signals.
5% of P0007 cases are fixed by replacing the ECM
Check These First (Before Buying Parts)
- Visually inspect the wiring harness and electrical connector leading to the fuel shutoff valve for any signs of damage, fraying, corrosion, or loose pins.
- Ensure your battery voltage is good; low voltage can sometimes trigger electrical circuit codes, though less common for 'high' circuit faults.
How to Diagnose P0007
- 1Inspect the wiring harness and connectors for the fuel shutoff valve for any visible damage, corrosion, or loose connections.
- 2Using a multimeter, check for proper voltage and ground at the fuel shutoff valve connector with the key on.
- 3Test the resistance of the fuel shutoff valve solenoid itself to ensure it's within manufacturer specifications.
- 4If wiring and the valve test good, use a scan tool to monitor live data and consider further ECM diagnostics.
P0007 on Popular Vehicles
Ford F-150
2003-2024On diesel F-Series trucks (F-250/350/etc.), P0007 is often related to the fuel shutoff solenoid on the injection pump or fuel filter assembly. Wiring damage from vibration or heat is common.
70% fixed by wiring repair or fuel shutoff valve replacement
Chevrolet Silverado
2001-2024For Duramax diesel engines, the fuel shutoff valve (often part of the fuel injection pump or fuel filter housing) can fail electrically. Check for chafed wiring near the engine block.
65% fixed by wiring repair or fuel shutoff valve replacement
Ram (Cummins)
2003-2024On Cummins diesel engines, P0007 can indicate a problem with the fuel shutoff solenoid. These solenoids can fail due to age or exposure to engine heat. Inspect the harness carefully for shorts.
75% fixed by fuel shutoff valve replacement or wiring repair
Frequently Asked Questions
What does P0007 mean?
P0007 indicates that your engine's computer has detected a high voltage condition in the electrical circuit that controls the fuel shutoff valve. This valve is critical for regulating fuel flow to the engine.
Can I drive with P0007?
No, stop driving. A P0007 code means the fuel shutoff valve is not functioning correctly. This can cause your engine to stall unexpectedly or prevent it from starting at all, leaving you stranded and creating a safety hazard.
Will P0007 clear itself?
No, P0007 will not clear itself. This code points to a hard electrical fault 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 vehicle's computer after several drive cycles or with a scan tool.
How do I fix P0007 myself?
Start by visually inspecting the wiring and connectors for the fuel shutoff valve for damage. If the wiring looks good, use a multimeter to test the voltage at the connector and the resistance of the fuel shutoff valve itself. If either test fails, you'll likely need to repair the wiring or replace the fuel shutoff valve.
How much does it cost to fix P0007?
DIY repair costs range from $50 to $400, primarily for a new fuel shutoff valve if needed, or just a few dollars for wiring repair supplies. Professional repair costs typically range from $150 to $800, depending on labor rates and whether wiring repair or valve replacement is required.
P0007 keeps coming back - why?
If P0007 keeps returning, it means the initial repair did not address the root cause. This often happens if a damaged wire was missed, the new fuel shutoff valve is also faulty, or the less common ECM failure was overlooked. A thorough electrical diagnosis is necessary to pinpoint the exact issue.
Will P0007 fail emissions/smog test?
Yes, P0007 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on is an automatic failure in most jurisdictions, and a fault in the fuel system directly impacts engine operation and emissions.
What's the difference between P0007 and P0006?
P0007 indicates a 'high' voltage condition in the fuel shutoff valve control circuit, meaning the ECM sees too much voltage. P0006 indicates a 'low' voltage condition in the same circuit, meaning the ECM sees too little voltage. Both codes point to an electrical fault in the circuit, but the specific nature of the fault differs.
P0007 on Ford F-Series (diesel)?
On Ford F-Series trucks with Powerstroke diesel engines, P0007 often points to issues with the fuel shutoff valve located on the injection pump or fuel filter housing. Wiring damage due to chafing or corrosion is a common culprit, as is a faulty fuel shutoff solenoid itself.
Questions to Ask Your Mechanic
Did you perform a full electrical diagnosis of the fuel shutoff valve circuit, including checking for shorts to voltage and resistance of the valve?
Good answer: Yes, I used a multimeter to check voltage at the connector, resistance of the solenoid, and continuity of the wiring back to the ECM. I found a short to power on the control wire.
What specific component did you identify as faulty, and what were the test results that led to that conclusion?
Good answer: The fuel shutoff valve solenoid had an open circuit when tested with an ohmmeter, indicating an internal failure. The wiring tested good.

Cost of Waiting
Ignoring P0007 means your engine will likely not start or will stall unexpectedly, leaving you stranded. This is a critical safety issue and prevents vehicle operation. A $50 wiring repair now prevents a tow bill and significant inconvenience later.
While You're In There...
If you are working on the fuel system, especially near the fuel shutoff valve (which can be integrated into the filter housing on some diesels), it's a good time to replace the fuel filter as a maintenance item.
Any time fuel lines are disconnected, replacing the associated O-rings or gaskets prevents future leaks and ensures a proper seal.
Tools You'll Need
- OBD-II scan tool
- Multimeter
- Basic hand tools (wrenches, sockets)
- Wire strippers/crimpers (if wiring repair needed)
- Electrical tape or heat shrink tubing
P0007 is a direct electrical fault, and while critical, it's usually straightforward to diagnose with a multimeter. Most repairs involve fixing a wire or replacing a single component, getting your engine running reliably again.

Your Next Steps
Step 1: Perform a thorough visual inspection of the fuel shutoff valve's wiring and connector. Look for any signs of damage, corrosion, or loose connections.
Step 2: If the visual inspection doesn't reveal the issue, use a multimeter to test the voltage at the fuel shutoff valve connector and the resistance of the valve itself. Compare readings to your vehicle's service manual.
Step 3: Based on your test results, you'll likely need to repair the wiring harness or replace the fuel shutoff valve. If both test good, further diagnosis of the ECM may be required by a professional.
