P0034

2017-10-10

Description:

  • The fault code P0034 indicates a low voltage condition in the circuit responsible for controlling the bypass valve of the turbocharger or supercharger. This can lead to reduced engine performance and inefficient operation of the forced induction system.

Possible Symptoms:

  • Check Engine Light illuminated

  • Reduced engine power and acceleration

  • Turbocharger or supercharger not functioning properly

  • Poor performance during acceleration

  • Decreased fuel efficiency

Possible Causes:

  • Faulty turbocharger or supercharger bypass valve

  • Wiring or connector issues in the bypass valve control circuit

  • Low voltage supply to the bypass valve control circuit

  • Faulty 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:

  • Test and replace the faulty turbocharger or supercharger bypass valve, if necessary

  • Inspect and repair any wiring or connector issues in the bypass valve control circuit

  • Ensure the bypass valve control circuit is receiving proper voltage supply

  • Test and replace the engine control module (ECM) if it is determined to be faulty
