What Does P0466 Code Mean?

    OBD-II Code P0466 is defined as a EVAP Purge Flow Sensor Circuit Range/Performance

    The evaporative control (EVAP) system captures any fuel vapors from the fuel tank and sends them through the vehicle's intake to be burned in the normal combustion process. The EVAP Purge Valve allows the fuel vapors to enter the engine through the intake. When the engine control module (PCM) detects the evap system has flow when it should not, it will set code P0466.

    Common Problems That Trigger the P0466 Code

    • EVAP purge solenoid failure
    • Powertrain Control Module (PCM) failure
    • Wiring issue
