I am having a problem with a evap code. The light just came on and the dealership is NO Help. I found a service bulliten on the vent line but now cant find it again. If anyone has an idea please let me know. I was a master tech for 22 years so I am not an idiot and dont like the way some rookie parts changer handled the problem. So I am fixing the problem myself. I just started using this web site. Seems to be a good one so far.

 

Thanks for the help Ted

Do you have the actual code number? There are a few diff codes for the evap system.

I had the same problem and code on my 05 silverado crew cab. My wife took it to the dealer and they fixed the problem for about 500 bucks. I shat myself when i found out ( i was out of town on business ) I checked into it and it was this small canister and filter that they changed. It would have taken me about 20 min to do. This canister slides onto the frame, not even a wrench was needed to install.

I contacted customer service for GM sort of got the run around then contacted the dealer . It probably helped me being a tech myself but when I started reading their warranty to them. ABOUT IT SAYING EMMISSION CONTROL DEVICE IN THE WARRANTYthey step right up and fixed it and only had my truck 24 hrs. You should check if they turned it in as a warranty problem if they did maybe GM would like to know. I am a GM fan and have been forever but I have had a couple of problems this is one and the other is pelling paint on the front bumper. I love my truck and would never concider any other except Toyota (which I own one of those also 225k on it ) I hope this helped some peopls problem has never be fixed and I have found this problem on models all the way back to 1999 internet is a great thing.

Thanks for trying to help.

    • Sure, but they do have some affordable options like the Trax, Trailblazer, Envista, and Encore. Some of these have a cheaper base price than the Civic, though the fuel economy isn’t as high. The main problem is that people WANT the highest trim with all the goodies and finance for like 7 years. That’s how ppl “afford” the more expensive vehicles. 
    • Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.
    • LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL
    • Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.
