I can clear the code and start the truck but as soon as I shut it off and when I start it up code is backing, I did have a problem with electric fan not wanting to shut off it heated my relay so I replaced it. Any help would be appreciated. Thank you

Hi Kevin, Which code is it, the p1497 or the p1491 code?

P1491: Radiator Fan Control Relay Circuit

P1497: Idle Air Control (IAC) System Performance

I would say it is the P1491 code because it has to do with the engine cooling fan. If you replaced the relay, I would clear the codes to see what happens. I would also check the fuse #9 in the fuse panel inside the truck and the fuse # 2 in the fuse panel under the hood. Here is the fan relay location to make sure we are on the same page. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
