Description:

  • Malfunction detected in turbocharger when vehicle is idle

Possible Symptoms:

  • Engine fails to start

  • A/C Blows Warm

  • Vehicle may stop running

  • Engine may appear to drive fine but surge at idle

Possible Causes:

  • Boost pressure sensor harness is open or shorted

  • Boost pressure sensor circuit poor electrical connection

  • Faulty boost pressure sensor

  • Faulty Turbo/Super Charger

  • Engine over temperature

  • Ignition misfire exceeds the calibrated threshold

  • Faulty Knock sensor (KS)

Related Parts:

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

Possible Solutions:

  • Check the voltage readings and resistance levels of the optical sensor, crankshaft position sensor, accelerator pedal position sensor, and the intake air temperature sensor

  • A PCM replacement
