Hello, my bumper was removed for painting and when replaced the reverse park control doesn't work like previously. It is less far reaching and misses things that it didnt before. I assume they installed sensors incorrectly so does anyone have info on correct installation of four sensors?

 

They probably damaged one of the sensors.

You could check to see if each individual sensor is working by:

1. Put the car in Reverse and have some step on the brake.....A responsible adult to avoid an accident.
2. Put a screwdriver to the sensor and your ear to the screw driver. You should hear "static"...If you dont, the sensor is not working.

Check for visual damage.

 

Thanks, I'll give that a try and see what happens. Get back to you.

 

USE THE E-BRAKE!!!!!!!! PLEASE AVOID AN ACCIDENT!

 

No problem, brake was held. All four sensors had the ticking noise when listening with screwdriver so all must be getting juice. One didnt seem to work right when placing hand in front of sensor. Three went to the solid beep with hand in front so I think one is off which seems to be the one the shop said they replaced. I did ask for the "broken" one back and they did give me one. Most likely they didnt place it correctly although it is aligned the same as others. I ordered a shop manual CD and hopefully it might have some details on installation.

 

Swap a good with the bad one to confirm it's faulty.

They are sensitive, I;ve had new ones be bad right out the box.
