2017-10-10

Description:

  • The fault code P0048 indicates that there is a high circuit signal detected for the turbocharger boost control solenoid. This may cause the engine to overboost, which can lead to engine damage or failure.

Possible Symptoms:

  • Illuminated check engine light

  • Rough idle or stalling

  • Engine overboost

  • Loss of power or acceleration

Possible Causes:

  • Faulty turbocharger boost control solenoid

  • Shorted or open circuit in the solenoid wiring

  • Loose or corroded electrical connections

  • Failed powertrain control module (PCM)

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 turbocharger boost control solenoid

  • Check and repair any damaged wiring or connections

  • Tighten or clean any loose or corroded electrical connections

  • Replace the powertrain control module (PCM) if necessary
