P0467 — Purge Flow Sensor Circuit Low Input
Can drive — fix at your convenience.
What P0467 means
This code means the purge flow sensor is sending a signal that's lower than the expected range during EVAP operation. It's commonly caused by a faulty purge flow sensor, wiring or connector issues, a short to ground, or a purge valve that isn't allowing proper vapor flow. The typical fix is replacing the sensor or purge valve and repairing any damaged wiring.
Common symptoms
- Check engine light is on
- Car drives normally in most cases
- Possible light fuel vapor odor
- Failed emissions or smog inspection
- Other EVAP purge codes may also appear
Common causes
- Faulty purge flow sensor
- Short to ground in the sensor signal circuit
- Damaged or corroded wiring or connector
- Stuck or restricted purge valve
- Faulty engine control module (rare)
Typical repair cost
$120 – $400
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0467 code?
Yes, usually. This EVAP code doesn't typically affect drivability or safety, so short-term driving is fine. Have it diagnosed within a week or two, especially if you have an emissions test coming up.
How much does it cost to fix a P0467?
Most repairs cost between $120 and $400. A purge flow sensor or purge valve replacement is the usual fix; wiring repairs can add to the total if connectors are corroded.
Is a P0467 code serious?
No, it's low severity. The EVAP system manages fuel vapors and rarely affects how the car runs. The main downsides are the check engine light and failing emissions testing.
What does 'low input' mean in a P0467 code?
It means the purge flow sensor's voltage signal is reading lower than the computer expects. This often points to a wiring short to ground, a bad sensor, or a purge valve that isn't flowing vapor correctly.
