On my '07 there is this annoying bug where the proximity sensor is beeping while there is not any obstruction in the front. I imagine it is one of the four painted sensors in the bumper. One of them has cracked paint. Is there someway to tell for sure and is the swap quick or does the bumper have to be pulled? I have a carista tool I could hookup.

 

Can you put it in a side or rear location and see if the locator image changes?
