Got a CEL light this morning and stopped by a friends house with a CEL tool to get the code read, Bad O2 sensor. What is the average labor (hrs) I should expect? Not sure if I should take it to the dealer or a indy shop.

 

I believe that there are four O2 sensors on the car so you would need to know which one has failed. Diagnostic code should identify. As an example of price, a new Bank 2 Sensor 1 cost the previous owner of my SC about $250 to replace three years ago at an independent shop. The part itself was about $80. Could be a bit higher at your friendly Lexus dealer. It may pay to do some shopping. I am guessing it also wouldn't be that hard to DIY if you are so inclined.

 

Yea I just got it done at a indy for $250. Didnt want to sit around and waste my time with it. Thanks for replying...
