Right Rear Height Sensor

Anyway! I took it to Lexus shop, they said the Rear Right Height Sensor is not working. Part on the receipt(sensor sub-assy, height) cost $393.00
plus labor $275.00
.So is there anyone in club had this problem before on the ul? At miles? and what cost?
And is there anything else that I would expect to happen on my air-suspension in the future?
ps. my car is out of warranty, original purchased on Sept,05
.Thank you every one who response!
