Can drive — fix at your convenience.
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.
$120 – $400
Varies by vehicle and root cause.
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.
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.
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.
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.
