P0007 is a generic OBD-II powertrain code indicating a high electrical condition in the Fuel Shutoff Valve “A” Control Circuit. The code can occur when the engine control module detects a voltage or electrical condition higher than the expected range in the fuel shutoff valve control circuit.
P0007 may be encountered on different manufacturers, including Jeep, Dodge, Chrysler, and other vehicles. The exact valve location, wiring design, control strategy, and diagnostic procedure vary by vehicle.
Category: Fuel / Engine Management
Type: Generic OBD-II
Definition: Fuel Shutoff Valve “A” Control Circuit High
What Does P0007 Mean?
P0007 means the ECM/PCM has detected an excessively high electrical condition in the control circuit for Fuel Shutoff Valve “A.”
The fuel shutoff valve is used by some engine and fuel-system designs to control or stop fuel delivery. Depending on the vehicle, the valve can be associated with fuel delivery, fuel-pressure control, or engine shutdown strategy.
The exact function should always be confirmed using the vehicle-specific service information.
P0007 on Jeep
On Jeep vehicles, P0007 should be diagnosed according to the exact engine, model year, fuel system, and wiring configuration.
Do not assume that every Jeep using P0007 has the same valve location or circuit configuration. The relevant fuel-system wiring diagram should be used to identify the valve, fuse, relay, power supply, ground/control circuit, and ECM/PCM connection.
Because Jeep shares many powertrain platforms with Dodge and Chrysler, similar diagnostic principles may apply to related applications, but the actual circuit must still be verified for the specific vehicle.
Fuel Shutoff Valve A Location
The physical location of Fuel Shutoff Valve “A” is not universal.
Depending on the vehicle, the component may be located near the fuel system, fuel pump assembly, fuel rail, fuel supply system, or another area specified by the manufacturer.
Always identify the valve from the factory wiring diagram and service information before testing or replacing it.
Fuel Shutoff Valve A Function
The valve's purpose is to control fuel flow according to the vehicle's fuel-system design and engine-control strategy.
When commanded by the control system, the valve may open, close, or change its operating state to control fuel delivery or assist with engine shutdown.
The ECM/PCM monitors the electrical circuit to determine whether the commanded operation is plausible.

P0007 Symptoms
- Check Engine Light.
- Engine may be difficult to start.
- Engine may crank without starting.
- Intermittent engine stalling.
- Reduced engine performance.
- Fuel-system-related warning conditions.
- Hard starting after the vehicle sits.
- Possible reduced fuel economy.
- Additional fuel-system or electrical DTCs.
Some vehicles may have few noticeable symptoms if the fault is intermittent or if the control system can compensate.
Common Causes of P0007
- Short to voltage in the valve control circuit.
- Open or damaged wiring.
- Damaged fuel shutoff valve.
- Failed valve solenoid.
- Corroded connector terminals.
- Loose electrical connection.
- Damaged wiring insulation.
- Water intrusion.
- Incorrect previous wiring repair.
- Faulty fuse or relay where applicable.
- Incorrect power supply.
- Control circuit driver problem.
- ECM/PCM fault in rare cases.
Fuse Box Check for P0007
A fuse-box inspection should be part of the diagnosis, especially if the vehicle uses a dedicated fuse or relay to supply the fuel-system component.
- Locate the relevant fuse using the vehicle-specific fuse diagram.
- Check the fuse condition.
- Verify power at the fuse.
- Inspect fuse terminals.
- Check the related relay where equipped.
- Inspect the fuse-box connectors for corrosion or overheating.
If a fuse is blown, determine the reason before replacing it. A short circuit may cause the replacement fuse to fail again.
How to Diagnose P0007
1. Scan All Codes
Connect a capable OBD-II scanner and record stored and pending DTCs.
Look for additional fuel-system, voltage, actuator, or communication codes. Related codes can help identify whether the problem is isolated to the valve circuit or part of a larger electrical fault.
2. Check the Battery and Charging System
Verify that the battery and charging system are operating correctly.
Abnormal system voltage can affect solenoid operation and control-circuit readings.
3. Identify Fuel Shutoff Valve A
Use the vehicle-specific service information to identify the exact component and connector terminals.
Do not replace a component simply because its name sounds similar to the definition of the DTC.
4. Inspect the Connector
Inspect the valve connector for:
- Corrosion.
- Moisture.
- Bent pins.
- Pushed-out terminals.
- Loose terminals.
- Broken connector locks.
- Damaged wiring near the connector.
5. Check the Control Circuit
Using the manufacturer's wiring diagram, test the control circuit for an unwanted voltage condition.
A high circuit reading may indicate a short to battery voltage, incorrect power feed, an open circuit depending on the circuit design, or a control-driver problem.
6. Check Valve Resistance
If the manufacturer specifies a resistance test, measure the valve or solenoid resistance and compare it with the vehicle-specific specification.
Do not apply one universal resistance value to every fuel shutoff valve.
7. Check Power and Ground
Verify the valve's power and ground/control circuits under the specified operating conditions.
Voltage-drop testing can help identify excessive resistance in power or ground connections.
8. Perform an Actuator Test
If supported by the diagnostic scanner, use the manufacturer's actuator test procedure to command the fuel shutoff valve.
Monitor the electrical response and fuel-system behavior while the valve is commanded.
9. Check the ECM/PCM Control Circuit
If the valve, wiring, power supply, and connectors test correctly, inspect the ECM/PCM control circuit according to the manufacturer's procedure.
Do not condemn the ECM/PCM until the external circuit has been thoroughly tested.
Common Repairs for P0007
- Repair shorted control wiring.
- Repair damaged wiring.
- Repair corroded connector terminals.
- Repair loose electrical connections.
- Replace a damaged fuel shutoff valve.
- Replace a failed valve solenoid where serviceable.
- Replace a failed fuse after correcting the underlying problem.
- Repair or replace a faulty relay where applicable.
- Repair damaged fuse-box connections.
- Repair ECM/PCM control wiring.
- Replace and program the ECM/PCM only when properly diagnosed as faulty.
Common Repair Mistakes
- Replacing the fuel shutoff valve without testing the circuit.
- Assuming P0007 automatically means a bad valve.
- Ignoring the fuse box.
- Ignoring a short to battery voltage.
- Testing the wrong component.
- Using the wrong wiring diagram.
- Replacing the ECM/PCM too early.
- Ignoring connector corrosion.
- Installing a replacement fuse without finding why the original failed.
- Failing to clear the code and perform a final verification test.
P0007 Severity
Moderate to High.
The severity depends on the vehicle and the function of Fuel Shutoff Valve “A.” If the fault affects fuel delivery or engine shutdown control, the vehicle may experience starting problems, stalling, or an inability to operate normally.
Estimated Repair Cost
The actual repair cost depends on the vehicle, engine, component location, labor rate, and confirmed cause.
- Diagnostic labor: approximately $50–$150.
- Fuse or connector repair: approximately $30–$150.
- Wiring repair: approximately $75–$350+.
- Fuel shutoff valve/solenoid: approximately $100–$500+.
- ECM/PCM replacement and programming: approximately $500–$2,000+ where applicable.

Final Takeaway
P0007 means Fuel Shutoff Valve “A” Control Circuit High.
For Jeep, Dodge, Chrysler, and other vehicles, the most important point is that P0007 identifies an electrical condition in a control circuit rather than automatically identifying a failed valve.
Start with the fuse box, battery voltage, wiring, connector, power, ground, and control circuit. Only replace the valve or ECM/PCM after testing confirms the component is actually defective.
