Turbocharger Compressor Outlet Valve Stuck Open

Where it lives

For P22C8, the description names the valve as the part involved.

Check these first

• A compressor outlet valve stuck open from carbon or a broken spring
• An open or shorted valve control circuit holding it open
• A mechanical binding in the valve linkage
• A failed valve actuator

What to do next

1. Command the compressor outlet valve through its range on a scan tool
2. Check the valve for binding or carbon buildup
3. Test the valve control circuit for open and short faults
4. Inspect the valve linkage and actuator
5. Replace the compressor outlet valve if it stays open on command
6. Clear the code and retest
