Common Causes of P0006

Parts most likely causing this code, ranked by probability

Fuel Shutoff Valve65% likely

The fuel shutoff valve itself is faulty, causing an internal short or open circuit that the engine computer interprets as low voltage.

65% of P0006 cases are fixed by replacing this part

Wiring or Connector30% likely

Damaged, corroded, or loose wiring and connectors in the fuel shutoff valve circuit can cause a low voltage signal.

30% of P0006 cases are fixed by repairing wiring or connectors

Engine Control Module (ECM/PCM)5% likely

A rare internal fault within the engine control module's driver circuit for the fuel shutoff valve can cause this code.

Check These First (Before Buying Parts)

  • Visually inspect the fuel shutoff valve's electrical connector and wiring for any signs of damage, corrosion, or loose connections. Ensure the connector is fully seated.

How to Diagnose P0006

  1. 1Visually inspect the fuel shutoff valve and its wiring harness for any obvious damage, corrosion, or loose connections.
  2. 2Using a multimeter, check for proper voltage supply at the fuel shutoff valve connector with the ignition on.
  3. 3Test the resistance of the fuel shutoff valve itself to determine if it's within specifications (refer to service manual).
  4. 4If voltage and resistance are correct, check for continuity and shorts in the wiring between the valve and the ECM.
  5. 5If all other components test good, consider testing the ECM's output for the fuel shutoff valve circuit.

P0006 on Popular Vehicles

Toyota Camry

2007-2024

P0006 is very rare on gasoline Toyota Camry models. If it appears, it points to a specific issue with the fuel pump control module or a dedicated fuel shutoff component if present, rather than a common failure point.

95% fixed by wiring repair or valve replacement

Honda Accord

2003-2024

Similar to the Camry, P0006 is not a common code for gasoline Honda Accord vehicles. Diagnosis should focus on the fuel pump control circuit and any specific fuel shutoff components if the vehicle is equipped with them.

95% fixed by wiring repair or valve replacement

Ford F-150

2004-2024

P0006 is more likely to appear on diesel F-150 models (e.g., Power Stroke) which utilize a distinct fuel shutoff valve. For gasoline models, it's rare and would point to an unusual electrical fault in the fuel delivery system.

95% fixed by valve replacement or wiring repair

Frequently Asked Questions

What does P0006 mean?

P0006 indicates that your vehicle's engine computer has detected a low voltage condition in the electrical circuit that controls the fuel shutoff valve.

Can I drive with P0006?

No, stop driving. A P0006 code means your fuel shutoff valve circuit is faulty, which directly impacts fuel delivery. Your engine will likely not start or will stall immediately, leaving you stranded.

Will P0006 clear itself?

No, P0006 will not clear itself. This code indicates a hard fault in a critical fuel system circuit. The underlying issue must be diagnosed and repaired before the code will clear, either automatically after several drive cycles or by using a scan tool.

How do I fix P0006 myself?

Start by inspecting the fuel shutoff valve's wiring and connector for damage. Use a multimeter to test for proper voltage at the valve and check the valve's resistance. If the valve or wiring is faulty, you can replace the fuel shutoff valve or repair the damaged wiring.

How much does it cost to fix P0006?

DIY repair costs for P0006 typically range from $100 to $400, primarily for a new fuel shutoff valve or wiring repair materials. Professional repair costs usually fall between $200 and $800, depending on labor rates and the specific part needing replacement.

P0006 keeps coming back - why?

If P0006 keeps returning, it points to an undiagnosed underlying issue. Common reasons include a faulty replacement fuel shutoff valve, a persistent wiring short or open that was not fully resolved, or a rare engine computer (ECM) fault that was overlooked.

Will P0006 fail emissions/smog test?

Yes, P0006 will cause your vehicle to fail an emissions or smog test. The Check Engine Light will be on, which is an automatic failure in states with inspection programs. Additionally, a faulty fuel shutoff valve can impact engine performance and emissions.

What's the difference between P0006 and P0005?

P0006 indicates a 'Fuel Shutoff Valve 'A' Control Circuit Low' condition, meaning the engine computer sees a voltage lower than expected. P0005 indicates a 'Fuel Shutoff Valve 'A' Control Circuit/Open' condition, meaning the computer detects an open circuit or no voltage at all.

P0006 on Ford F-150?

P0006 is less common on many standard gasoline Ford F-150 models, as the fuel shutoff function is often handled by the fuel pump relay. However, if your F-150 has a specific fuel shutoff valve (more common on diesel or certain direct injection systems), the diagnostic steps for the valve and its wiring apply directly.

Questions to Ask Your Mechanic

Did you check the voltage at the fuel shutoff valve connector and compare it to specifications?

Good answer: Yes, I measured X volts, and the spec is Y volts. It's either too low or missing entirely.

What was the resistance reading of the fuel shutoff valve itself?

Good answer: The valve showed X ohms, but the factory specification is Y ohms, indicating an internal fault.

Intermediate - Requires electrical diagnostic skills and a multimeter to accurately pinpoint the fault. Access to the fuel shutoff valve can vary by vehicle.

Cost of Waiting

Ignoring P0006 means your vehicle will not start or will stall, leaving you stranded. There is no 'waiting' period for this code; it requires immediate attention to restore vehicle operation.

While You're In There...

Fuel Filter

While not directly related to the P0006 electrical fault, if you are working on the fuel system, replacing an old fuel filter is good preventative maintenance and can prevent future fuel delivery issues.

Tools You'll Need

  • OBD-II Scan Tool
  • Multimeter
  • Wire Strippers/Crimpers (if repairing wiring)
  • Basic Socket/Wrench Set
  • Safety Glasses

Related Codes

P0006 points to an issue with your vehicle's fuel shutoff system. While it prevents driving, the problem is usually an electrical component or wiring, which is a straightforward fix for a qualified technician or an intermediate DIYer.

Your Next Steps

1

Step 1: Perform a thorough visual inspection of the fuel shutoff valve and its wiring. Look for frayed wires, melted insulation, or corroded terminals. Ensure the connector is securely attached.

2

Step 2: If the visual inspection reveals no obvious issues, use a multimeter to test for proper voltage at the fuel shutoff valve connector with the ignition on. Then, test the resistance of the valve itself. Compare your readings to the vehicle's service manual specifications.

3

Step 3: If the valve or wiring tests faulty, replace the fuel shutoff valve or repair the damaged wiring. If both test good, you may need to trace the circuit back to the ECM to check for continuity and shorts, or consider an ECM diagnosis (less common).

Note: The specific location and type of 'Fuel Shutoff Valve' can vary significantly between vehicles, especially between gasoline and diesel engines. Diesel engines often have a more distinct fuel shutoff solenoid or valve. Always consult your vehicle's specific service manual for component location and testing procedures.
