I just picked up a 2004 LS430U with 46K miles and have an issue where the front passenger tire sensor is telling me the pressure is wrong. I've manually checked the pressure and it's perfectly fine (32PSI).

There's new tires on the car, so I'm guessing when they put the tires on they messed up the sensor.

First, is there any way to disable the annoying alarm sound that plays every time the car comes to a stop?

Second, is there any way to reset the system to make 100% sure the sensor is bad? Also, can I get an actual reading from the sensor (i.e. 13.5psi) to see if it's truly a bad sensor or something else? If so, how can I do this?

Thanks!

Yes, there is a reset method after changing the tires, i dont remember how. check the manual, or hopefully someone will chime in here with the procedure.

Here is a good read about the tire sensor, and how they work in the LS, and the difference between the new system in the '07 cars.

I called up Lexus and the service manager had me hold down the "Tire Set" button below the steering wheel (above where your right knee would go) and then hit it agian, and voila. The problem disappeared.

Now, I'm getting the front right sensor going off whenever I'm in drive and come to a stop... (the park assist)

Has anyone had problems with their park assist sensors on the LS430?

Thanks!
