i have a 2012 nissan sentra, 2.0, auto, 114k miles. Runs and drives great, maintenence kept religiously. Throttle just stops working. Disconnect battery for 5 minutes all good for a while again , had garage replace throttle body, still done it. He replaced again thinking maybe a defective throttle body. Still does it. No codes. Full diagnostic at garage. What do i do to fix this?
did he check your pedal sensors
Not sure,
Replace the throttle position sensor unit.
It could be an accelerator pedal position sensor problem at the pedal for sure. One other thing those cars are slightly prone to is the wires will brake where they go to the throttle body. If you wiggle them and look at them you may see a wire on the verge of braking just not fully broken yet
