Help me figure this out. My parking sensors do not work. I check the fuse, it's OK. The back up lights work fine. There is no clicking noise from the sensors when the car is in reverse. What else can I check to isolate the problem? It's a 2006 XKR convertible.

 

If all 4 are clicking, and there is no sound at all when put in reverse from the speaker, suspect the speaker went out

 

I listened to each sensor and there is no clicking noise from any of them.

 

Problem corrected. I wiggled all the wires in the back bumper that are attached to the sensors. It's magic, now the parking sensors work.

 

Sometimes electronics do seem like magic, but you sure showed that bumper who's boss! Stick around and enjoy the forums while your car is not giving you grief, you will learn a TON about your car you cannot even imagine right now.
