P0466

2017-10-10

Description:

  • The OBD-II fault code P0466 indicates a problem with the purge flow sensor circuit, which is used to monitor the flow of fuel vapor from the evaporative emission control system (EVAP) to the engine. This code is triggered when the sensor detects a range or performance issue.

Possible Symptoms:

  • Check Engine Light illuminated

  • Rough idling or stalling

  • Decreased engine performance or power

  • Fuel odor coming from the vehicle

  • Failed emission test

Possible Causes:

  • Faulty purge flow sensor

  • Wiring or connector issues in the purge flow sensor circuit

  • Vacuum leaks in the EVAP system

  • Clogged or damaged EVAP canister

  • Faulty EVAP vent solenoid or purge solenoid

  • Faulty powertrain control module (PCM)

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:

  • Test and replace the faulty purge flow sensor, if necessary

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

  • Inspect the EVAP system for vacuum leaks and repair as needed

  • Check and replace the EVAP canister if it is clogged or damaged

  • Test and replace the faulty EVAP vent solenoid or purge solenoid, if necessary

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