Fuel Shutoff Valve Control Circuit Low
The fuel shutoff valve control circuit is receiving a voltage signal that's too low, like a dimmer switch stuck at minimum brightness. The engine computer can't properly command the valve to open or close fuel flow.
The ECM monitors the voltage signal sent to the fuel shutoff valve solenoid control circuit. It expects a specific voltage range when commanding the valve open or closed. If the measured voltage drops below the minimum threshold, the ECU logs a low voltage fault, indicating a wiring problem, bad solenoid, or driver circuit failure.
| Parameter | Normal Range | Fault Condition |
|---|---|---|
| Shutoff valve control voltage | 11-14V when commanded on | Below 5V or open circuit detected |
| Circuit resistance | 4-8 ohms coil resistance | Above 20 ohms or infinite resistance |
Code P0006 is a moderate fault. You can generally drive to a workshop, but avoid long trips or high-load driving (motorway, uphill towing) until it is diagnosed. If the code keeps returning after clearing, or if you notice the symptoms listed above worsening, do not delay professional diagnosis. Many moderate codes have multiple possible root causes — a mechanic with live OBD data can identify the exact fault more efficiently than part-by-part trial and error.
Once the fault is repaired, P0006 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.
The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.
