P0467
EVAP Purge Flow Sensor Circuit Low
EVAP (emissions)
Generic OBD-II
Low
What it means
P0467 means the signal from the evaporative-emissions purge flow sensor is reading lower than the expected range. This sensor measures fuel vapor flow through the purge system into the intake, so a low signal usually points to a wiring short, a bad sensor, or a purge valve that isn't flowing. It affects emissions monitoring, not how the car drives.
Low
Can I keep driving? Yes — this is an emissions-monitoring fault; the car runs and starts normally, but the EVAP monitor won't complete until it's fixed.
Common symptoms
What you'll notice
- Check-engine light on
- No noticeable change in how the car drives
- May fail an emissions/readiness test
- Sometimes a slight fuel smell if a purge fault is also present
Common causes
Most likely first
- Faulty EVAP purge flow sensorLikely
- Short to ground or open in the purge flow sensor signal wireCommon
- Corroded or loose sensor connectorCommon
- Purge valve stuck or not flowing, giving a low sensor readingLess often
- ECM signal-processing fault (least common)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check for companion purge-valve codes (P0443-P0446).
- Inspect the purge flow sensor connector and wiring for damage or a short to ground.
- Backprobe the sensor signal and compare its voltage against the service spec with the purge valve commanded on.
- Replace the purge flow sensor if it reads low with good wiring; verify the purge valve actually flows.
- Clear the code and run the EVAP monitor to confirm the repair.
FAQ
Quick answers
Is it safe to drive with P0467?+
Yes. It's a low-severity evaporative-emissions fault that doesn't affect how the car runs or starts. Fix it so the EVAP monitor can pass an emissions test.
Can I just clear P0467?+
You can, but it returns once the purge flow sensor circuit is tested again if the wiring or sensor is still faulty.
