P0007: Fuel shutoff valve A control circuit reading high
Fuel shut-off valve A control circuit high
Severity: Severity not verified — if the car runs badly, have it inspected
The reference pages describe the circuit fault but give no reliable guide on drivability, and no bulletin or manual we have read rates its severity.
It gets more serious if:
- Inspect soon: Get it inspected soon if the engine stalls, will not start or loses power.
P0007 in short
P0007 means the computer sees a voltage that is too high in the control circuit for the fuel shutoff valve. Likely causes are a wiring or connector fault, a failed valve, or the engine computer driver. It is mostly seen on diesel engines. A shop should test the circuit before parts are replaced.
A fuel shutoff valve is an electrically controlled valve that opens or closes fuel supply. The computer drives it and watches the voltage in the circuit.
P0007 is set when that control circuit reads high, which can mean a short to voltage, a bad connection that raises the reading, or a fault in the valve or computer output.
We have no bulletins or model-specific data for this code, so the causes below are general.
Most likely causes
These are general causes for this code across vehicles. None is specific to one make or model.
Cause 1: Wiring or connector fault in the valve control circuit
Common general cause- Why it ranks here
- A high-voltage condition in a control circuit most often traces to a damaged wire or connector, which is the cheapest thing to check.
- What would change this
- Rises if the wiring shows damage or the voltage reading is high at the valve plug. Falls if the circuit tests clean.
Cause 2: Failed fuel shutoff valve
Common general cause- Why it ranks here
- Reference pages list the valve itself as a cause when the circuit tests good.
- What would change this
- Rises if the valve resistance is out of spec. Falls if it tests normally.
Cause 3: Engine control module output fault
Possible — needs testing- Why it ranks here
- A computer driver fault is possible but rare, and only after wiring and valve are cleared.
- What would change this
- Rises if wiring and valve test good and the code returns. Falls otherwise.
What to test first
Start at step 1. Each result tells you what it means and where to go next.
Step 1: Read all codes and freeze-frame data and note any fuel pressure or no-start codes stored with P0007.
IfOther fuel system codes are present
It meansHave a shop test the fuel system circuits together.
IfP0007 only
It meansHave the valve circuit tested.
Step 2: Have the valve connector, wiring and voltage at the valve tested against the service information.
Warning:Fuel system work can involve pressurised fuel and fire risk. Let a shop do it.
IfWiring is damaged or the voltage is out of range
It meansA wiring or connector fault is likely.
Points to: Wiring or connector fault in the valve control circuit
IfThe circuit is good but the valve is out of spec
It meansThe valve is faulty.
IfEverything tests good
It meansSuspect the computer.
Symptoms
- Check engine light
- Hard starting or no start
- Engine stalls or loses power Gets more serious: stop and have it checked.
How to fix
Step 1: With the engine off, look for damaged wiring or a loose connector at the fuel valve if it is easy to see.
Parts and cost context
- Engine control module (ECM / PCM):Rarely the cause. Rule out wiring and the valve first. Labour varies; get a quote.

Is P0007 a gas or diesel code?
It is a generic code for a fuel shutoff valve circuit and is mainly seen on diesel engines. Check your service information for where the valve is on your vehicle.
