Cylinder 11 Exhaust Valve Control Circuit Performance

Where it lives

For P3486, the part to look at first is the valve named here. The description of P3486 puts it on cylinder 11.

Check these first

• An intermittent open or short in the cylinder 11 exhaust valve control circuit
• A slow or sticking exhaust valve control solenoid on cylinder 11
• Carbon buildup limiting exhaust valve actuator travel on cylinder 11
• A control module that is losing feedback from the cylinder 11 exhaust valve circuit

What to do next

1. Read the stored code and freeze frame data on a scan tool
2. Command the cylinder 11 exhaust valve control solenoid on and off
3. Compare the commanded and actual cylinder 11 exhaust valve positions
4. Inspect the cylinder 11 exhaust valve actuator for binding or carbon
5. Replace the cylinder 11 exhaust valve control solenoid if the circuit tests good
6. Clear the code and retest
