My tech stream shows bank 1 sesnor 1 code. I want to replace the sensor, but have a question on the part. The Lexus dealer wants $220, and Advanced Auto has two different Denso parts that both say they are for the upstream sensor. The dealer is also further away, by about 20 minutes, so I don’t want to drive that far unless it is needed.
So which sensor should I get, and/or should I replace both sensors since the vehicle has 318,000 miles?
