I have a 2008 Lexus ES350 and on my latest trip to the car wash the high pressure caused one of my rear parking sensors to get pushed inside the bumper, I assume due to a weak retaining clip and/or extreme high water pressure. The bezel is still in place but the actual sensor appears to be pushed inside the bumper. The best case situation for me would be that the retaining clip broke or became unfastened. In addition, I'm not sure what the sensors look like but there is the possibility that the tabs that the retaining clip lock onto have been broken.
My question is this, how do I access the rear sensors? I have found instructions on how to access the ones on the front by removing the bumper, but not the rear. It appears access may be gained through a cover in the trunk. Also, I have access to Toyota's repair website but could not find any instructions on this topic, so if someone knows where to look for the topic on Toyota's website just tell me where to find the instructions I would appreciate it. Or is there a post that I overlooked?
Thanks.
