Yep, this is a failsafe warning due to a bad throttle body or accelerator pedal sensor failure. We need to run the codes to figure out which.

Most of the time shops will replace both at the same time FYI, here are the parts I am talking about. Check out the images (below). Please let us know what happens.

My best guess Is the vaule on the throttle body is closed and not being able to open because you can hear it wanting to start it just cant.
