Check Engine Light and A/T Oil Temp lights on...

... when in key is turned to Accessory. When i start the engine, these lights disappear. I purchased my '15 tacoma about 2 weeks ago and has 300 miles on the ODO. Anyone else have these lights on while in ACC? If not, should i be calling the dealership in the morning?

 

Wouldn't worry about it. Cant recall if mine does it but if they're not on when the thing is running, don't worry.

 

Doesn't anyone read the Owners Manual? It is all in writing and perfectly normal. THey should all go out when the truck is running.

 

whats a owners manual?

 

just kidding. but i did look through it and didnt see that in there. thanks

 

I have a 2015 tacoma with the same problem, did you ever figure out what the problem was?

 

Ok i asked this on an old thread ,but my problem is different and cant find anyone who reported a solution to this,my 2012 tacoma AT oil tem came on and the truck quickly died after that,how ever i restarted the truck with no problem the first time and drove 15 min to my house,ever since the issue has happened twice again,now am not sure why or how this is related but another taco owner had same issue after doing a u-turn,which coinsidentally is the same way my problem started,just minutes after doing a u-turn,has anyone had the same issue and what was the solution to this??

 

Part of the bulb check and power on self test. EVERY vehicle does this....

sorry, that was to the OP's post, failed to see how old it was...

That is likely something else.... Could be a sensor problem or wiring harness issue. Is the transmission hot/well worked when the light comes on (hot ambient temp/driving up steep grades/towing something)... does the light make any sense in the context you are using the vehicle? If not it could be wiring or sensor related.
If you are doing one of the above, stop doing it

fluid level could be low also, which would amplify a heat problem (if there isn't as much fluid to disperse the heat)

 

None of the mentioned...left chuckee cheese with my kids and went to drop off my sister 10 min away from the place,drive the truck on normal conditions,perfect weather ,nothing at all that could have caused this,fluids look all normal,exept in this case am not able to see the trans fluid level because of the lack of a dipstick for it..
