Description:

  • This fault code indicates a problem with the turbocharger wastegate solenoid circuit which controls the flow of exhaust gases to the turbocharger. This may result in poor engine performance and/or reduced fuel efficiency.

Possible Symptoms:

  • Decreased engine performance

  • Reduced fuel efficiency

  • Illuminated check engine light

Possible Causes:

  • Failed wastegate solenoid

  • Faulty wiring or connections in the circuit

  • Corrosion or damage to electrical connections

  • Failed engine control module (ECM)

Related Parts:

  • Turbocharger/Supercharger: Turbocharger compresses in more air into the engine, hence producing more power output. Problem leads to power loss

Possible Solutions:

  • Replace the wastegate solenoid

  • Check and repair any damaged wiring or connections

  • Clean or replace corroded electrical connections

  • Replace the engine control module (ECM) if necessary
