Turbo/Supercharger Boost Control Circuit Low
on 2016 GMC Terrain 2.4L I4 · FWD
What this code means
The signal from the turbo boost control solenoid circuit is below the expected threshold. This prevents proper boost pressure regulation.
Symptoms
- Check Engine Light
- Underboost condition
- Sluggish acceleration
- Limp mode activation
- Excessive turbo lag
Common causes
- Short to ground in boost solenoid circuit
- Faulty boost control solenoid
- Corroded wiring connector
- Failed turbo wastegate actuator
- Low system voltage
Diagnostic steps
- Measure voltage at boost control solenoid connector
- Inspect wiring for shorts to ground
- Test solenoid coil resistance
- Check wastegate actuator rod movement
- Verify battery voltage and PCM ground
Repair notes
Repair short circuit or replace boost control solenoid. Check wastegate linkage for binding.
