Fuel Shutoff Valve Control Circuit High
The P0007 code indicates that the Powertrain Control Module (PCM) has detected a high voltage condition in the fuel shutoff valve control circuit. This valve is responsible for cutting off fuel flow to the engine in certain conditions, such as during a collision or when the ignition is off. A high voltage reading suggests a short to power, a faulty valve, or a wiring issue. This can lead to improper fuel delivery, potentially causing the engine to stall or not start.
01. Most Common Causes
- Short to power in the fuel shutoff valve circuit
- Faulty fuel shutoff valve
- Damaged wiring or connectors
- Corroded terminals
- Failed PCM (rare)
02. Symptoms You Will Notice
- Engine stalls or fails to start
- Check Engine Light illuminated
- Reduced engine performance
- Fuel odor
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm the code and check for other codes.
Step 2: Visually inspect the fuel shutoff valve and its wiring for damage, corrosion, or loose connections.
Step 3: Test the fuel shutoff valve resistance with a multimeter; compare to manufacturer specs.
Step 4: Check for voltage at the valve connector with the ignition on; should be within spec.
Step 5: If wiring and valve are okay, test the PCM output circuit for shorts or opens.
