Severity

highDrive cautiously with reduced performance; seek repair immediately to prevent engine damage.

Summary

Code P0035 indicates that there is an issue with the turbocharger bypass valve control circuit being too high in voltage. This problem affects the turbocharger's ability to regulate boost pressure properly.

Symptoms

  • Engine light illuminates
  • Decreased engine performance and fuel efficiency if solenoid is stuck open
  • Potential overboost condition leading to internal engine or turbocharger damage if solenoid is stuck closed

Common Causes

  • Wiring short to positive voltage
  • Failed boost control solenoid
  • Powertrain control module failure
  • Poor connection at boost solenoid connector
  • Moisture or corrosion in the boost solenoid connector

Diagnosis

  1. Test the boost solenoid by blowing air through it and checking for proper switching when power is applied.
  2. Check wiring for shorts, corrosion, or poor connections.
  3. Inspect PCM for faults in supplying voltage and ground to the solenoid.

Fixes

  • Replace faulty boost control solenoid

FAQ

What should I do if my engine light comes on with code P0035?
