Check engine light

So I'm working and it comes on, I'm only at 86,947, and it's serviced regularly, I know I need a new air filter and my next oil change isn't Til 90,000, any ideas what it might be? Thanks

 

check the gas cap, make sure its tight.... reset the ecu ( disconnect the battery for a few minutes).... If it comes back on get it scanned

 

I was going to take it to a local shop but it's gonna cost me a lot more then borrowing one, I'll get it scanned tomorrow and post it

 

Its worth buying a pocket scanner for just this thing. $40 from harbor freight or $60 for the orange actron which can be found anywhere. If you pull the negative battery cable for a reset, you'll erase your fuel trims as well as a bunch of other diagnostics which are based off a certain number of drive cycles.

My wife's corolla with 135000 miles kept throwing codes, and I was able to narrow down with the codes that were thrown to a common intake manifold gasket problem and fix it.

My next venture is a toyota techstream mongoose cable + techstream 7 software....I can check on everything on all 3 of our Toyotas
