Im going to be going to LA, Cali on the 10th and I went to Walmart on 05/30/2021 (I know a big mistake but my dad convinced me. I’m a girl and have been learning a lot about cars cause of my own car troubles but I still am pretty clueless.) I got a oil change, my tire pressure checked, and my engine air filter changed. Everything was fine until 2 days later.
Here is when my current trouble starts.
I went to the gym in the morning and my car was fine, tire pressure light was on as always, everything normal. Later the day, my family and I go to Denny’s and I notice that my “Engine Service Soon/check” light is on and I just think “WHAT THE F&$K IS THE PROBLEM NOW!”. After Denny’s, I head back to Walmart to see if they can look over it as part of the “contract” car release forms you sign states that if you have a problem after a service with them, you can go back to get it looked it, as long as you don’t go to another shop after your Walmart visit as they will no longer be responsible. I go there and they tell me that they can’t help me because they don’t do diagnostics but I argue but they shut me down.
I went to O’Reilly’s across the street to borrow the code scanner and I got the code P0456 - “Evaporative Emission System, Leak Detected (very small peak)”. The guy at the front desk tells me he can check my engine for me real quick and he looks over it and notices my filter box.
He tells me I’m missing a clip for my air filter (My box has 2 that keeps it closed) and that that’s the reason for the code as there is a gap that air is getting in/out. I look over and I see that I am missing a clip and it all clicks together.
Those Walmart Bas*ards!
The form I got back had a technician comment that says “1 air box clip missing”. The thing is, I’ve never had this problem/code before and I remember having and checking for both clips after my uncle was done with the engine service and I’ve never touched the filter box before. It seems to me that they lost it and didn’t want to replace it or be responsible and decided to claim that it was “missing” (I feel so stupid for not taking a picture before leaving it).
I didn’t think think much of the technician comment beforehand as I looked up how a missing air filter clip can affect your car and I saw one comment to just forget about it. To not be worried, I forgot about it (my mistake I know). Now, 2 days later after the 30th, I find out about the code and go home. I decided not to drive my car until I get a new clip as I know that one’s air filter is their engine first line of defense and should be protected.
I order a new clip on Amazon that should arrive tomorrow, but I am worried that once I put the clip and reset the code, the light will come on again.
I know there could be other causes such as a fault gas cap, Evap system Hose, Vapor Canister, Purger Valve, etc…
I have checked my gas cap and it’s fine, it’s a new gas cap I bought after I had replaced the old one it previously had. I have no idea how to change my evap hose or Valve, ive looked up videos on how simple and easy it is to do it at home, but I do not want to do it myself due to fear Of messing it up and I don’t want to bother my uncle about it.
Do you guys think it’s because of my missing air clip? Or could it likely be the other possibilities?
Thank you for reading!
