  • Illuminated check engine light

  • Reduced engine power or acceleration

  • Poor fuel economy

  • Engine may run rough or hesitate during acceleration

Possible Causes:

  • Faulty turbocharger bypass valve

  • Failed turbocharger boost sensor

  • Shorted or open wiring in the boost sensor circuit

  • Loose or corroded electrical connections in the boost sensor circuit

  • 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 faulty turbocharger bypass valve

  • Replace the failed turbocharger boost sensor

  • Check and repair any damaged wiring or connections in the boost sensor circuit

  • Tighten or clean any loose or corroded electrical connections in the boost sensor circuit
