Bought my first truck today, 2005 tacoma. Real exited until the check engine light came on just as we got it home. I'll have to have it checked to see what's up tomorrow.

Sounds like they had it turned off so potential buyers would not see it

Probably catalytic converter issue, if so just keep driving it.

Have it checked quick to see potential problem was something you been handed by previous owner.

Hope it something simple.

Private or dealer Seller?

It was also inspected today.... took him two days to do it....

Small dealer

2 days to inspect it? Or to get around to inspecting it?

Shouldn't be a big deal. You should be able to get it to go off. Check your owners manual on how to do it. They are designed to come on after so many miles or after so many miles since the oil was changed. On my 2016 it comes on every 5000 miles.

Either way I would call the dealer to inform them in case it's something more major.

I think but not sure on lemon law or a 3 day period you have to change your mind on the deal.

Monday morning ha said he had dropped it off to get inspected, called me later that night and said they didn't get to it and would have someone else do it today.

I believe your right if worse case happens, just trying to figure out what it is before time is up.

It's usually something minor . Sometimes the local auto parts stores will plug in a code reader for you at no charge

I had one do that. I called the dealer, he told me to unscrew and tighten the gas cap. It worked. Dont know why.

Vacuum screws with sensors

X2 had it happen a couple times

Every vehicle I own has the light on, one 2500 chevy I own has has the light on since it hit 100k and it now has 300k so its probably not nothing major

The 'ignore me' light came on?

Good luck with the new truck.

Robert, if the light is on steady probably emissions, gas cap, O2 sensor ext if the light is blinking probably something more serious. Good luck.

Isn't it the maintenance required light you are talking about? The check engine light is for more serious issues (sometimes).

The check engine light is on in my Tundra, I believe it is a vacuum issue caused by a bad gas cap, just ordered a new one.

Welcome to your beginnings of adulthood. Like said before, probably emissions or gas cap.
