A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.
Possible causes
- Vent valve
- The vent valve connector or wiring by the fuel tank
What you can do yourself
- This isn’t urgent: it doesn’t affect driving, but the ECU can’t check for fuel vapor leaks.
- The vent valve usually sits by the canister near the fuel tank, under the car, where its connector fills with dirt and corrodes.
OOleg’s tip: check the connector
Often the cause is simple — there is no contact in the connector (plug). Look at the connector from the back: remove the rubber seal and you will see whether a wire is corroded or has come off completely. Corrosion shows up as green deposits. Ideally, gently pull each wire towards you one at a time: a sound wire stays in place, while a corroded one simply comes off — it needs to be repaired.
Unplug and inspect connectors with the ignition off.

This is the Hyundai meaning. On other makes this number means something else: if your car isn’t a Hyundai, change the make at the top.
