New Alt = Check engine light!?!
So I installed my new 170amp alternator today. Now I have a check engine light that won't go away. I will be leaving in a little bit to go to auto zone and see if they can tell me what is up, does anybody have any ideas?
Also is there any way that I can check to make sure that my alternator is working like it is supposed to? thanks

Ok so I went to auto zone and ran the code.
It turned out to be a P0113-IAT Sensor 1 Circuit High Input. I cleared the code and all has been good since. I asked the guy at auto zone about the IAT sensor and why it would have went off. He said that more then likely it was a "hick-up" signal since the code cleared and since what I did should have had nothing to do with the new alternator. I am glad about this!
graniteguy- i don't have a voltmeter, but I am going to try and find somebody with one and check to make sure everything is working good. I turned my truck on and off a ton of times since I put it on and no issues, so I figure it is working good.

That's weird. The IAT is part of the MAFS. Only way to have that unplugged is to unplug the whole MAFS plug. I have done that before and have driven with my MAFS unplugged (Was doing some testing) and had no CEL light.
I guess it was a hickup. I would take some CRC Electrical Contact Cleaner and clean the MAFS/IAT incase there is anything on there.

LOL, yah.
FYI I did un-hook the MAF when I took off the intake tube to install the alternator. I did run the truck for a little bit before re-installing the intake tube and figure this is what pulled the code first. I would figure that the code would go away when I re-plugged everything, but guess not. It's all good now so :D
