Sorry if this is in the wrong spot I wasn't sure where to put it and this was my best guess.
Truck is 98 Ram 1500 4x4 with about 48k miles on it.
Long story short, my mothers POS trailblazer was having throttle body problems and it needed cleaning. I get the brilliant idea that since I am doing one, I might as well do mine while I am at it.
Immediately after I start the truck and move it out of my way and I get a CEL. I check it thinking I missed something and everything looks right, but I get code P0720.
I am comfortable replacing the sensor, but the rub is I got this code when I first installed the air intake. I don't believe it's the sensor but I could be wrong. Any thoughts?
