Did you buy a cheaper A/F sensor or Denso. There are many selling fake Denso's. I'd sure like to know if the ones under $40 last at least a couple of years because that's about as long as we are going to keep our RX300.
You cannot be a parts changer without any evidence that the part is defective. You have to test that defective part and or follow it up with further diagnostic. I will never ever replace a part unless I have Evidence.
