P00FEEVAP System Tank Vapor Line Restricted/Blocked
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- The evaporative emission system stores fuel vapour from the tank in a charcoal canister and later purges it into the engine. P00FE means the vapour path between tank and canister is restricted or blocked. That matters because a blocked line can hide the tank side from the leak test and disturb tank venting and refuelling. Ford, where P00FE replaces its own code P144A, checks this once per drive cycle during the cruise leak test, while purging with the vent valve closed, and confirms suspicious pressure responses with an intrusive test. VW used the same code on the 2013–2019 Golf, where the diagnosis covers the purge valve and the leak detection module. Typical causes are kinked or pinched lines and charcoal grains from a broken canister.
- What you may notice
- Check engine light on
- Fuel nozzle clicks off early when refuelling
- Hiss or vacuum when opening the fuel cap
- Usually no change in driving
- Likely causes
- LikelyKinked, pinched or misrouted vapour line between tank and canister
- PossibleCharcoal canister broken down, grains blocking lines or valves
- PossibleRollover or fill-limit valve at the tank stuck closed (e.g. after overfilling)
- RarePurge valve or leak detection module faulty
- RareTank pressure sensor reading wrong
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
