Diesel Check Engine light/ Code P00AF

[Irishguy1973]

Live in South Louisiana where it was 90 degrees yesterday and while accelerating uphill on a bridge my Check engine light, electronic throttle control light and electronic stability light came on. It seemed to stay at a speed of 60 mph and than the Jeep would let me accelerate here and there. Codes cleared when I was home and cleared the CEL with the scan tool. The Tool read code P00AF. I did have my DEF light come on as I was low on fluid. Don't know if that had something to do with the codes. Any advice in my steps to check this out? Jeep is 21 Diesel with 34,000 miles. Haven't had any issues as of yet. Jeep is not my everyday and stays on tender when not used. I think I had a message on dash service Electronic stability control too! All help greatly appreciated and will post conclusions if it helps others!

Thanks
Chris

Hey
This is what pops up
Maybe just running hot?
