HEY CAN ANYBODY HELP ME PLS I NEED HELP WITH A FEW THINGS WHAT DOES A APP SENSOR DO AND AF SENSOR DO AND CAN I DO THE JOB MYSELF THANKS.

 

app senor is accelerator position sensor. your gas pedal is not directly connected to your throttle body, it uses the app sensor then transfers that info via computer to the throttle body. If you open the hood and remove the passenger side plastic cover from the hood closest to the windshield its a little black box kinda right behind that strut tower brace. its sometimes hard to get to without the right tools. if you remove the brace you can get to it pretty easy. after taking it apart, the new part should just swap right out. the o2 sensor or af sensor can be easy depending on which one it is.
