Tahoe: New Tires = Engine Light On?

[pikestabber]

Just had new skins put on my 2004 Tahoe. After just a handful of miles the check engine light came on. Could this be damage to the ABS sensor or something along those lines? Is it true that Auto Zone and similar big parts stores will scan vehicles for free? I don't want to just ignore it, but I don't want to pay a bunch to have it cleared if it's nothing... My rear is still sore from the price of new tires...

I'm not sure about AutoZone but Oreilly will check them for free. Possibly a coincidence because an ABS problem should light the ABS light not the check engine light. Did you fill the tank lately? If so, make sure the cap is tight. Was any other service done at the time the tires were installed?

you can do a scan and reset at auto stores.

tire guy said he could only think of the ABS issue if one tire was smaller than the others but the odds of that are about zilch.

I did actually just fill up and I'll check that out first. The gas cap has been a bit wonky lately so it'd be nice if that was the problem.

Yeah, after I typed this I realized that ABS is a separate light and not an emission trigger anyhow. One thing I read, and this seems out of the box, is that new tires can change gas mileage which can trigger an emissions check. Possible?

I'll bring it to O'Reilly's next and see what code they come up with. I just liked it better when you didn't need a degree in computer science to run a vehicle... (sour grapes)

...it was a loose gas cap.

(sheepishly enters comment...deletes HSO account in shame)

Lol, thanks for the suggestion, Macgyver55 (and others). I'd rather be embarrassed for free than to be right and shell out greenbacks.

that's funny.

I once spent a few days trying to get my ATV to work it was driving me nuts. Had to find the right plug wrench in metric, couldn't find a plug, took it apart and couldn't get it back together. My neighbor stopped by and turned the fuel to reserve and it started immediately. Main tank was empty... I feel your pain.

Thats the kind of fixes we like to see! Funny post
