This is my code...what the heck could this be cause by?? I did switch to a new Alt. 200amp actually. But I hooked it up exactly how the original was and now I get this code. The reason I switch is because I went with a ASP underdrive pulley and I need more amperage!!!

 

Switching to that Alt is what its caused by, just go in and delete the code, wont hurt a thing!

Your stock alternator is a 3-wire. 1 for battery hookup (charging post), one to turn the alt on (L terminal), and one for the PCM to sense alt output/load (F terminal). Your new alt is probably a 2-wire, just the output post and the L terminal. The PCM is not seeing a signal on the F terminal circuit like it wants, so it is freaking out. Like chrisj6 said, just disable the code in the tune and you'll be fine.

 

Nice thanks again chris you come through everytime

Thanks also chrisj6. I appreciate the response times
