Q: What does code P0465 mean?

EVAP Purge Flow Sensor Circuit. P0465 indicates that the powertrain control module has detected an abnormal signal from the evaporative emission purge flow sensor circuit, which monitors the flow of fuel vapor from the charcoal canister into the intake manifold. The computer compares the sensor's voltage or frequency output against expected values during purge events and sets this code when the signal falls outside the acceptable range.
