Wow! Great information. I wasn't aware of that either. No more rounding up for me. Thanks for the info.

Greetings, Just got back from grocery shopping. On the way to the store I got a check engine light pop up that says "Emissions System Problem". My car only has 20,271 miles and I've brought it in for all of the schedule maintenance checkups at the dealership where I bought it. I don't think any dealership service departments are open today since it's Sunday. If I took it to AutoZone, would they be able to plug in the analyzer and tell me the specific issue? Thanks!

Have you fueled up lately? If so, try removing the gas cap and placing it on as per the manual, usually one click tight.

The 5th gen is a cap less system.

A few years ago this happened to my wife's car and my car all in the same week. I figured it might have to do with low quality gasoline. Since then, when it happens I have filled the car with mid-grade or premium fuel from a "high end" gas station that has cleaning fuel additives and within a few miles, the warning goes off. I don't know if you agree with my logic, but it seems to work for me!

Wasn't sure if they were or not.

I would think they could pull codes for you that might narrow it down a bit? Did you get gas recently? A loose gas cap could be the issue.

The 2020 CRV does not have a gas cap. The fuel door has a fitting that covers the filler tube.

That was established 20 posts ago and I acknowledged my error.

I guess some don't start from the beginning.

My bad, I forgot about the crazy Honda design. 🤣

It's NOT a crazy "Honda" design. A lot of automakers have gone to a "capless" gas filler tube. GM, Ford and others have it and I think they came out with it before Honda did.

 

[SVTfocusO3]

Dont think he meant it like that, hence the "🤣 "

Won't even be a gas cap before long.

Yikes! Thank you so much for the new info. I'm gonna tell everyone I know not to round up!

It won't cause the DTC you have on your vehicle. The DTC you got refers to a solenoid valve problem which can be a component issue or wiring connection, etc. Topping off your tank wouldn't cause this. BTW, the topping off thing "can" cause liquid fuel to enter the canister IF it is very, very overfilled but this isn't easy to do as the fuel tanks do have an air space that can't be filled unless you really keep trying to add more and more fuel after the click-off. Also, how soon the nozzle clicks off depends on how fast you are refueling. If you have the nozzle trigger full on at maximum fill rate, it will click off sooner than if you're filling it slowly with the trigger say, 1/3 or 1/2 way only. I usually fill my tank wide open until I get close to what I think is getting full and then slow down the fill rate. Then when it clicks off, I know it's pretty full and just "round" to the next even dime. If you hold the nozzle trigger at maximum fill rate, when it clicks off you usually find that the tank isn't quite as full (sometimes the gauge will show it's just below the "Full" mark).

Loose gas cap says check gas cap. Seems a lot of Honda Crvs are having emissions problems

There is no gas cap.

To add an important nuance in addition to what bassn386 has shared here: There is an internal cover plate (with a seal on it) that flips closed down inside the plastic cappless fuel fill port. If actually forms the primary seal for the capless fuel tank. If for any reason it gets damaged, you will have emissions vapor leakage from the fuel tank.

How can it get damaged you might ask? Use of an old school fuel pump nozzle that still has those catchy spring coils around the neck if inserted too far can break or damage the seal plate. Same is true if ever refuel with the classic gasoline can and nozzle (which is why Honda gives you a special little funnel that the manual says to use if you ever have to refuel from a fuel can).

There have been a handful of owners who have reported damaged fuel seal cover plates in their capless CRVs. Most often from a lousy nozzle at the local gash station and over zealous insertion by the driver.

Okay, just got back from AutoZone. The printout reads: Power Train System code P24C0 - Canister Change Over Valve Close Malfunction.

I don't know what any of that means.

REMEMBER that ! when fueling always stop when it clicks ,do not overfilled it will mess up the gas canister and send a ( code ).

Thank you for replying. My car does not have a gas cap. The gas door has a cover thing that seals the hole.

Sorry, I've never heard the term "rounding up" in this context. What does that mean?


Thank you for the link, I will check it out

Usually called "topping off" the tank.
Should not be done on vehicles with charcoal emissions cannisters, like the CRV.

It's a good idea to stick with Top Tier fuel (not premium) from the major name brands as the level of additives and detergents are different. Non top tier may affect sensors and stuff. It happened with mi Infiniti. Switched back to mobil or shell and problem solved.

Update: So my car spent a couple of days at the dealership last week and they told me it was some sort of evaporator part that had to be ordered to arrive in two more weeks. However, the service guy said my car is still driveable since the only thing happening is that it is polluting the atmosphere.

All this is covered under warranty. Speaking of which, my main gripe is that the Honda Care warranty only reimburses the cost of a rental at $35 per day (6 days max). I'm sure that $35 per day price hasn't changed in years but you know what has changed? The price of rent cars and everything else. I think Honda Care needs to bump that up $10 or $15 so we can afford the extra daily charge for insuring the rental.

"evaporator"

Yeah, sounds close enough. Thanks for the update Dood!
