A/t temp and check engine light on no start

Hey there I have a 2010 tundra 2wd 5.7 and it was running fine but when I turned it off the a/t temp and check engine light came on but when I jump started it the a/t temp light and check engine light went away so I left it on but when I shut it off it cranked up again then I tried it again and the same thing happened a/t temp light and check engine light came on and it just cranks haven’t tried jump starting it again any one have a clue on what it could be

 

Sounds like you may need a new battery, our trucks do funky things with a bad one. I would have it load tested, then move on with the diag if its not that. Good Luck.

 

I was thinking the same it is a high mileage car so I’m hoping it’s just a battery
