Cylinder 5 Deactivation/Intake Valve Control Circuit High

Where it lives

For P3436, the circuit described runs through the valve. The description of P3436 puts it on cylinder 5.

Check these first

• A short to voltage on the cylinder 5 intake valve control circuit
• An open ground at the cylinder 5 intake valve control solenoid
• A failed cylinder 5 intake valve control solenoid
• A failed driver in the control module for the cylinder 5 intake valve circuit
• A chafed cylinder 5 intake valve control wire touching voltage

What to do next

1. Read the cylinder 5 intake valve control status on a scan tool
2. Command the cylinder 5 intake valve control solenoid on and off
3. Test the cylinder 5 intake valve control circuit for a short to voltage
4. Check the cylinder 5 intake valve control ground for continuity
5. Replace the cylinder 5 intake valve control solenoid if the circuit tests good
6. Clear the code and retest
