Engine light and Trac light on

my engine light and trac light just came on Amy idea what it might be. Truck still seems to run fine no noise or power loss. Going to get it looked at next week when I'm back home.

 

Did you hit Trac off button by accident?
That's the only time mine ever comes on.

 

If your check engine light is on, you have thrown a code. Go to any autoparts store and borrow their code reader for free, and check what it is. No need to take your truck in and be charged $100+ to pull the code. Without having a code to go from, I'd guess you either have a check engine light and bumped your TRAC button (try pressing it and seeing if the TRAC light goes off), or you have some sort of ABS/TRAC sensor fault that is causing the system to be disabled, causing the check engine light and the TRAC light.

 

Mine came on awhile back and it was a loose Gas cap. But could be a big range of issues

 

90% of time? This^ check cap, if loose, tighten unhook battery for few minutes.

 

Loose cap would not cause the TRAC light to come on. It would throw an evaporative emissions leak code.

 

Loose cap does indeed cause trac light to come on.

 

I get how a loose gas cap will make the CEL come on but what does it have to do with the TRAC light coming on? Not saying it isn't true just wondering why since it doesn't seem like they would be related to one another at all

 

I can't say from experience on the Tacoma. But that surprises me as the systems are unrelated.

 

Without getting into the direct cause and effect aspect, trac comes on by default with CEL when cap loose at least in later 2nd gens

 

Here is a pic

 

Did you check the gas cap? If it can spin and click it was loose. If not some other reason for CEL TRAC new caps are single click fyi

 

Check your gas cap.

Aside from that, I had this happen in my truck earlier this year completely out of the blue. It disappeared an hour later on it's own and hasn't come back.

 

Not the gas cap. Just tried it. Took it off and put it back on started the truck still on

 

Does so

 

You need to have the code cleared

 

Yes

 

I siphoned gas off my roof rack recently and failed to click cap. threw CEL TRAC unhooking batt cleared

 

It may not be the cap then. If you are basing that it is not the cap just by closing, closing cap will not clear code, even if you drive a bunch of miles. Older cars would clear self after sensing correct pressure in tank for a period of time, not tacos
