The P0006 diagnostic trouble code (DTC) indicates that the Fuel Shutoff Valve "A" control circuit is experiencing a low voltage condition. This valve regulates fuel flow to the engine, and a low voltage signal suggests potential electrical issues, such as insufficient power supply, poor connections, or a failing valve

1. Low voltage supply to the valve.
2. Faulty Fuel Shutoff Valve "A".
3. Short circuit or damaged wiring in the control circuit.
4. Malfunctioning Engine Control Module (ECM).

• Difficulty shutting off the engine.
• Possible stalling or inconsistent engine performance.
• Check Engine Light (CEL) illuminated

1. Inspect and test the wiring for shorts or damage.
2. Verify the voltage supply to the fuel shutoff valve.
3. Test the valve for proper operation and resistance.
4. Replace or repair any damaged components.

Quick diagnosis and resolution are necessary to avoid further complications and maintain engine reliability.
