Here is a second TSIB -- it's about a steering column groan noise on an 01 LS430. It shows another view of the components of the system. TSIB_ST003_01_Steering_column_groan.pdf

When our Air/Fuel Ratio sensor failed last August, I forced Lexus to replace it under their goodwill warranty policy. If I had to pay for it, the cost would have been about the same as what you were quoted. My wife's 2000 RX300 has suffered from many failed components during 2003 and 2004, far more than this vehicle should have experienced. As a result, I've battled with Lexus on multiple occasions and have basically had more than $9,000 worth of service performed on this vehicle at no charge to us. I research the problems thoroughly, prepare my case, and then dig in and do battle with Lexus until I get what we need. So far I'm batting 1.000 with repairs including replacing the transmission, the exhaust manifold, the front strut mount rubber bushings, the Mass Air Flow sensor, the Air/Fuel Ratio Sensor, the rear main oil seal, and a couple of other items. Very few owners possess the stomach and relentless willpower to battle service departments like I do. But it works for us and I don't mind creating a ruckus in the dealership if I need to. The key is to remain professional and knowledgeable, but absolutely ruthless as well. But we'll never have another RX in our household after this one runs its course. My wife will return to her beloved Grand Cherokee line-up. We've had three of them and it's a bulletproof vehicle that has been far more reliable for us than this fragile, underpowered, under-engineered RX300 crackerbox. I look forward to pushing it off a cliff when we're done with it.... Good luck with your Air/Fuel Ratio sensor.
