Fuel Shutoff Valve Control Circuit High
The P2667 code indicates that the powertrain control module (PCM) has detected a high voltage condition in the control circuit of the fuel shutoff valve. 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 signal may be caused by a short to power, a faulty valve, or a wiring issue. This can lead to improper fuel delivery, potentially causing stalling, no-start, or reduced engine performance.
01. Most Common Causes
- Short to power in the fuel shutoff valve control circuit
- Faulty fuel shutoff valve
- Damaged wiring or connectors
- Corroded electrical connections
- Faulty PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine stalling or no-start condition
- Reduced engine power or hesitation
- Fuel pump running continuously
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm the code and check for additional codes.
Step 2: Visually inspect the fuel shutoff valve wiring and connectors for damage, corrosion, or loose connections.
Step 3: Test the fuel shutoff valve control circuit voltage with a multimeter; compare to manufacturer specifications.
Step 4: Check for a short to power by disconnecting the valve and testing the circuit.
Step 5: If circuit is okay, test the fuel shutoff valve resistance and replace if out of spec.
