Fuel Shutoff Valve A Control Circuit High
This code means there's a problem with the part of the car that controls the fuel shutoff. It's like when a light switch is stuck in the 'on' position, but for the car's fuel system.
The P0007 code is triggered when the engine control module (ECM) detects a high voltage condition in the fuel shutoff valve 'A' control circuit.
The fuel shutoff valve is responsible for stopping the flow of fuel to the engine when necessary. A 'control circuit high' condition indicates that the voltage in the circuit is higher than expected, which could be due to a wiring issue, a faulty valve, or a problem with the ECM.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the fuel shutoff valve for proper operation.
• Repair or replace damaged wiring.
• Replace the faulty fuel shutoff valve.
• Replace or reprogram the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Engine Performance
• Have the vehicle inspected by a professional.
• Do not ignore the Check Engine Light.
• Avoid driving the vehicle until repaired to prevent further damage.
Repairs may be covered under the vehicle's powertrain warranty. Check with your dealer for specifics.
The P0007 code is relatively rare and often associated with specific vehicle models known for fuel system issues.
Moderate – This issue should be addressed soon to avoid potential engine performance problems.
Driving with a malfunctioning fuel shutoff valve can lead to engine performance issues and may not comply with emissions regulations.
• Engine at operating temperature
• Vehicle parked on a level surface
The fuel shutoff valve is typically located near the fuel tank or along the fuel line.
Q: Can I drive with a P0007 code?
A: It's not recommended to drive with this code active, as it can lead to engine performance issues.
Q: How do I reset the P0007 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
