I drive a 2001 IS 200 SE. I got this problem with the Lexus Parking Sensors.
Whenever it rains, and I put the car in the reverse gear, the parking sensors start beeping (a continuous beep)as if I am about to bang into something. I went and wiped the sensors but still the same result. However after it stops raining and gets dry, its starts operating normally (regular beep depending on the distance).
It is just one of the sensors on the back side as when I use it I can hear the other sensors working properly, but cant figure out which one.
This problem is new and has started since the last month or so.
Any advice would be highly appreciated.
