Cylinder 10 Deactivation/Intake Valve Control Circuit Performance

Where it lives

For P3474, start at the valve the description names. The description of P3474 puts it on cylinder 10.

Check these first

• An intermittent open or short in the cylinder 10 intake valve control circuit
• A slow or sticking intake valve control solenoid on cylinder 10
• Carbon buildup limiting intake valve actuator travel on cylinder 10
• A control module that is losing feedback from the cylinder 10 intake valve circuit

What to do next

1. Read the stored code and freeze frame data on a scan tool
2. Command the cylinder 10 intake valve control solenoid on and off
3. Compare the commanded and actual cylinder 10 intake valve positions
4. Inspect the cylinder 10 intake valve actuator for binding or carbon
5. Replace the cylinder 10 intake valve control solenoid if the circuit tests good
6. Clear the code and retest
