P2667 Code - Fuel Shutoff Valve 'B' Control Circuit High
Quick Answer
The P2667 code indicates a problem with the fuel shutoff valve 'B' control circuit being high, meaning that the voltage in the circuit is above the specified range. Common causes include Faulty Fuel Shutoff Valve: The issue may stem from a malfunctioning fuel shutoff valve itself, causing the control circuit to register a high voltage, Electrical Wiring Issues: Problems with the wiring connecting the fuel shutoff valve to the vehicle's electrical system can result in a high voltage reading, Poor Ground Connection: A poor ground connection in the circuit can also lead to high voltage and trigger the code. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
