Hello, I checked this forum and tried Google Search . My white, 2009, es350 was recently hit by hiway debris which knocked the right front sensor out of the bumper. I'm not sure if its in the engine compartment because of all the molded plastic parts. The left front sensor beeps and produces a yellow marker on the dash when too close to an object but the right front display only displays a red dashboard marker. Rear sensors still work fine. Can some one tell me if the reasonably priced sensors sold on ebay will actually work on my car without having anything programmed or if there's a better option? Thanx Paul R.

 

if you decide to replace them maybe these will help

 

Thanx for the diagrams. They may prove helpful.
