P0468

2017-10-10

Description:

  • The fault code P0068 indicates a high voltage condition in the EVAP purge flow sensor circuit. This suggests an issue with the sensor responsible for monitoring the purge flow in the evaporative emission control system. High voltage readings can disrupt proper fuel vapor management, potentially causing emission-related problems.

Possible Symptoms:

  • Check Engine Light illuminated

  • Possible fuel odor

  • Failed emission test

  • Irregular idle or stalling

  • Decreased engine performance

Possible Causes:

  • Faulty EVAP purge flow sensor

  • Wiring or connector problems in the sensor circuit

  • Malfunctioning EVAP canister purge solenoid

  • Blockage or restriction in the EVAP system

  • Faulty engine control module (ECM)

Related Parts:

  • Purge Flow Sensor: This sensor helps to prevent fuel vapors in the fuel tank from escaping into the atmosphere. Problems lead to fuel loss

Possible Solutions:

  • Inspect and replace the faulty EVAP purge flow sensor, if necessary

  • Check for wiring or connector issues in the sensor circuit and repair as needed

  • Test and replace the malfunctioning EVAP canister purge solenoid, if required

  • Inspect the EVAP system for blockages or restrictions and clear them

  • Consider replacing the engine control module (ECM) if all components are functioning correctly
