I’m unsure of what I should do concerning a recent ‘check engine’ light(yesterday) that’s come on. There’s also a digital read-out that said to tighten the gas cap.
Like a lot of cars, I have a lid over the gas cap that ‘clicks’ when it’s fully shut and flush to the car. I’m certain I did this after my last fill up but found it unsecured yesterday morning. I didn’t see any granules or other instance of a substance that may have been added to my tank but with the latch unsecured and the light coming on I have to wonder. I, or someone else could have bumped into or whatever but who knows?
Now here’s the clincher. my cap hasn’t securely fit on the tank opening for some time now(I know, one of those things that’s easily replaced but always gets lost in the back of your mind). I t would go on and no matter how much you turned, it wouldn’t ‘lock’ into place. As a quick fix my dad put some kind of paste-like substance to ensure air didn’t get in(this was some time ago) and I’ve been operating like that since. As little as I have to drive, vehicle issues were never as a high a priority as I’m thinking they should have been before now. Given this incident, I bought a new one(locking) and put it on.
Could the lack of a seal cause not just the digital read-out but also the ‘check engine’ light to come on and remain on even after the new cap is secure?
My mind immediately goes to the worse possibility but don’t know if there’s any way to try to narrow things down a bit. Any help would be appreciated.
