Cold Start Turbocharger/Supercharger Wastegate Actuator B Range/Performance

Where it lives

For P2C9C, start at the actuator the description names.

Check these first

• A wastegate actuator B that does not track its commanded position at cold start
• Carbon or soot binding wastegate actuator B
• A weak wastegate actuator B solenoid
• A linkage that binds when cold

What to do next

1. Command cold start wastegate actuator B through its range
2. Compare actuator B position to the commanded value
3. Clean soot from the wastegate linkage
4. Test the wastegate actuator B solenoid
5. Replace wastegate actuator B if it will not track
6. Clear the code and retest
