    Hey! great forum, just join about a week ago. Had a cel (check engine light) on my Silverado l and had it checked out and turned.

    I crawled under the truck and located the evap solenoid at the front of the gas tank. Anyone know if this was standard in the and newer?.

    Anyone know if this was standard in the and newer? My truck throws a random misfire code, a system too lean code, and a intake manifold stuck open code is what I believe it said last. Glad you got yours fixed, those warning lights are a pain. I cleared it two more times and it has not come back in two tanks. I have a phenomenal YouTube cutaway of the system and how it works

    Return to Vortec 5. First, go to the forum you'd like to create a topic in. Then, click the New Topic button. The cap was not loose. At the end of the day, the CEL is a glowin' I understand this is typically one of two solenoids, caused by topping off the tank guilty as charged or random failure under the hood. I crawled under the truck and located the evap solenoid at the front of the gas tank. Mine has the remote filter that has been routed on top of the transmission.

    Anyone know if this was standard in the and newer? I searched and found that this was a common solution to earlier years, wondering if the fix has already been applied to mine before I bought it. Any experienced mechanics have suggestions as to how to get the old guy off? It uses 'quick connect' fittings that are barbed and ain't gonna come off. Another quick hit, this is my first time using the inTune as a code reader, but it can't actually clear the codes returns an error message.

    Anyone know if the tuner gets overridden by an active code that hasn't been fixed? I replaced mine with it it's the single port style and just zip tied the vent hose out of the way. Easy fix, but no more topping off the tank for me as that's what causes the failure! You don't need the remote filter. Exact same thing happened to me in my after I went through some high water maybe not related Its started with gas cap message, then cel of small and high leaks, then finally after clearing them with the intune yes it works, yours is messed up, try updating the real showed on the cel.

    I cleared it two more times and it has not come back in two tanks. Even then I would remove it and try to blow it out I have a phenomenal YouTube cutaway of the system and how it works Oh and the failure is caused by the solenoids becoming obstructed with debris This causes them not to activate, watching the cutaway video makes it all make sense.

    I'm gonna swing by my autoparts store and see if they have the Delco part in stock, hopefully a quick fix. I guess the repair was done before I got the truck, I'm going to try using the same long vent tube and take a look at the remote filter, hopefully it isn't plugged. Damn environmental bull shiza Must have freed itself! I keep saying ima take it out and clean it up but so long as it's working I don't wanna mess with it But you can do whatever you want.

    I already have the remote filter installed first owner fix or shipped stock, not sure. Rather than drawing directly from an open tube, I plan to see if the current filter is in good shape and keep this in the inlet line on the much cheaper part Rock Auto here I come! If anyone else runs into a P, go for the single-port valve from the older models AC Delco Simple splice, solid unit, I don't think there is a chance in hell of the thing getting clogged up unless you do heavy driving in dusty conditions.

    Takeaway - don't overfill the tank. Stop when the pump tells you to. My own dumb mistake I know. My thanks to TooTall for the tip on the older model part. I'd suggest you go ahead and take out the old remote filter and extended hose, easily snakes out from under the truck without any tools I just went from a dual port to a single port on my 06 z It was quick and easy. Only thing is my check engine light is still on.

    I'm guessing it might take a little time? I was wondering how the fumes escape if there's only one port. I guesse I don't understand the single port. I know the canister is charcoal and stores fumes.
