I have a 2007GS450h with the Parking Assist "radar" sensors in the front and rear bumpers.

Currently, the right front corner sensor is stuck on -- it indicates I am near an object when, in fact, I am not.

I've checked to see that nothing is stuck to the sensor (or anything else visibly wrong with it).

Are there any trouble-shooting things I can do before I take it in for service?

(I know I can turn off the parking assist completely, but I miss it when I don't have it...)

Thanks.

disconnect your battery for few minutes and see if the problem goes away

seemed to work with some members from before, if not, take it to the dealer, could be just malfunctioned sensors, easily fixed under warranty

take it for service right away while it's stuck. They can't do anything if they don't see a problem.

Mine is intermittent and so happens that when i take it to the dealer, the problems stops. I replaced one of the sensors already, but now have couple others that need to be replaced.

is it dirty? try wiping it. Mine did the same thing and I wiped the sensors and it went away. Same concept as when it snows and ice is stuck on the sensors I guess.
