Frequently Asked Questions

What does circuit low mean on the purge flow sensor?

The PCM receives a voltage below the normal range, typically from a short to ground in the wiring or a failed sensor.

Is P0467 urgent?

No, it is a low-severity EVAP monitoring code. The vehicle drives normally; only emissions testing is affected.

Can water cause P0467?

Yes, water intrusion into the sensor connector can short the signal to ground, especially on sensors mounted low on the vehicle.
