Parking Sensor problems
Do any of you guys have an issue with sensors going off pretty much any time the car is in reverse, regardless of being near an object?
I have this problem from my back sensors. I've cleaned them to make sure there was no dirt or anything on them, but still have the issue.
It's driving me insane! I never had this problem with my LS430.

I had this same problem with my front ones, and the dealer replaced them according to the salesman. This was done prior to me taking delivery, so I don't have any work order.

i think dirt is usually the culprit. since you've cleaned them, time to have them replaced. especially if it's easy to demonstrate/duplicate. hopefully still under warranty.

I posted similar recently. Mine has just been the rear right side. I also took mine to the dealer and they couldn't find a problem.
While I appreciated the suggestions I got (among those to disconnect the battery for 5 minutes), I just have a gut level feeling that if there's not an actual fault in the sensor, there must be some physical issue around it.
I shot some compressed air at/around the sensor on the back side of the bumper. Since I was lying directly under it, I know that some debris came out...I got a good taste of it.
The sensor hasn't gone off since, but it hasn't had all that many opportunities yet. If it goes several days without going off, I'll consider it probably fixed.

same problem on my 06 gs430
I have the same exact problem on my '06gs430!
It started about a month ago and I noticed that it went off a lot more often when it was really hot out. Normally when I parked in an outdoor lot, the outside temp hit 90+ and then when I backed out of the spot, the red indicator and alarm went off.
It goes in this wknd for service, so it was something I was going to ask my dealer about.
If anyone finds out if there is an issue on the sensors, pls let us know.
thanks-

usually a small dint from rocks hitting it will trigger it, but its kinda hard for a rock to hit it from the rear, but maybe a small dint would trigger it, me and a friend of mine have that same issue, but in the front

Fixed? I don't know. I do know that it had been a near daily occurance.
I suppose if you're having the problem and you have access to a compressor, it's worth a shot.
I've probably jinxed myself now.

I had this problem to and, initially, they couldn't replicate the problem but when picking it up from service, the service tech saw it when driving the car out to me. They replaced the sensors on the back bumper free of charge. Good Luck!

I just bought an 04 LS430. This is actually my first post I don't even have a sig yet. The car is great except I am having a problem with one of my parking sensors. If you are looking at the rear bumper, it's the middle-left sensor. It is on constantly when the car is in reverse.
I tried cleaning it and disconnecting the battery for a few minutes, neither did anything. I put my parking brake on with the car in reverse and bumped the area around the sensor. A couple times it flinched but it didn't really do much. Then I blocked the sensor completely with my knee right up against it and it shut up. What does that mean? Bad sensor? How can I know for sure before I spend the money on a new one without paying satan (every other car forum I've been on calls the dealership satan) to diagnose it?
