What does this mean?
We’re reasonably sure your “evap vent valve” or “solenoid” has failed. This is part of the vehicle’s emissions control system. The fuel system on modern vehicles is sealed, preventing fuel vapors from escaping the vehicle (which are considered harmful to the environment). The “evap” system manages these fuel vapors. Vapors are stored in a canister, external to the fuel tank. When the emissions system thinks the engine is ready, these fuel vapors are fed or purged into the engine to burn them off. The purge valve controls this flow of these vapors into the engine. The Vent Valve allows outside air to flow into the gas tank when pressure is too low or too high. The vent valve is common failure, failing due to accumulated dirt or varnish.
On a scale of 1 to 10, we rate this to have an urgency of 8. Some repairs have very low urgency, and we give those a 1. With these repairs, you can wait for as long as you would like, because it will not ever result in harm to you or your vehicle. These are usually cosmetic damages.
We consider a 5 to be something that will eventually need to be done, but you can likely get away with holding off for a while if other things are more pressing. However, if a repair is close to a 10 (or at a 10), this means you should NOT be driving the vehicle, and should get this repaired as soon as possible.
What happens if I wait?
As long as the car is running fine (smooth, no blinking check engine light) and there are no gas fumes, there is unlikely to be mechanical consequence to waiting to get it fixed. Of course it will not pass emissions inspection.
How complicated is this repair?
- This job has no tools required, and can be completed by just about anyone.
- This requires a relatively handy person, but little experience working on cars exclusively.
- This warrants an average person who’s done a fair amount of car repair. Think the weekend mechanic who’s done a brake job or two!
- At this difficulty, the average mechanic could do the job, but you wouldn't want to do it yourself without a fair amount of experience.
- This job is very specialized, requiring very expensive tools only a specialty shop has and a high level of expertise.
