My vehicle is a 1999 Honda Civic with approximately 155,000miles to it. I will try to explain as best as I can how this all began…
Well, the first thing to occur was the metal “latch” on the handle you pop to get at your gas cap fell off so anyone could come by and remove my gas cap and/or siphon my gas. Well, I was dumb and instead of parking it in my garage thought oh, no one around here would do that (I was proven wrong). So, like the dumb blonde I am, suprise, someone stole my gas cap- he/she did not remove any gas, just took my cap.
So, after work that day (I noticed this in the morning on my way to work), I stopped at AutoZone and explained the situation. Now, on my way to AutoZone- the check engine light came on. The clerk mentioned that was likely due to the gas cap being off. He ran a code check to confirm it. He also said it could take a few days for everything to “cycle” through and for the check engine light to go off. I talked to a couple other people who said the same thing.
Besides that, I needed a new gas cap but because I cannot afford to purchase the whole latch, I had to do with the gas cap. I purchased a locking one for safety. Well, a few days later- the check engine light went away.
Now, about a week later, I had to fill up my tank. When I locked it, I must have done a really good job because I could not turn the key to unlock the cap. It would not budge. So, again, I brought it back to Auto Zone and thankfully someone was still there and able to loosen it. I have decided from now on, it is best not to lock my gas cap to avoid further issues.
So, all of this happened within a month. So, the second time I go to fill up my tank, I noticed on the way home the check engine light came on again. I am assuming it is due to the gas cap being too loose or unlocked or something regarding it. I plan to go to AutoZone again to see if they can run their code meter thing-a bob to confirm.
I guess, I am wondering if anyone out there can confirm my suspicions and whether this will be an ongoing issue? Also, I am due for an oil change and I worry the mechanics will notice the check engine light on and see dollar signs. The car has not ran any differently than it did before someone stole my gas cap. I always keep my fluids to where they should be. Their have been no new noises/sounds or other indicators flashing on my dash.
I’m sorry if this is cumbersome. I have tried to make this post simple but, usually, that may result in my overcompensation and than the post becomes even more confusing.
Thanks everyone in advance
