Check Engine Light/ O2 sensor
Have a 05 RX330 and the check engine light is on. Auto parts store said code that it was showing is Bank 1 and 2 are running lean. Took to a mechanic and says that I may need to replace o2 sensors. What does this run $ ?
It could be a hefty bill as the bank 1 sensors in a hard to reach place compared to bank 2. I'd say if it is the O2 sensors, it will cost you around ~$100 each sensor for Denso alongside labor which I would assume could take max 2 hours.

There are 4 o2 sensors so write down the DTC codes and post them here. Ive seen my downstream bank1 sensor while under my car before and it's accessible. Not sure about the upstream one, prob half way up the firewall. Start with the code(s)

I had an 05 Highlander. When the O2 sensors went, it wasn't a might be this or that, it was clear it was an O2 sensor. You need to post the codes here to have someone tell you exactly what it is.
