Changed mine today as a matter of fact! Bank 1 Sensor 1 near the firewall, under the car on a 2000 ES300. $169.99 Bosch part from Advance Auto, $13.89 socket as well, and just a standard socket set. My code was P1130, but same part. About 1.5 hrs from start to finish. Not bad for a middle-aged woman w/minimal car fixing experience in the 96* heat! I am pretty happy with me. :D
Sensors probably can be had cheaper elsewhere, but I have plans to drive this weekend and couldn't wait. This one was local and in stock and cheaper then Napa's $212.
Best Wishes to you!
Thanks for your help. It's funny that you mention Advanced Auto. I had them run the test and they showed me the code, yet they never mentioned that they had the part.
Do you know the actual Bosch part # and where this part is located? What was the $13.89 socket? I have a metric socket set. Is that sufficient or do I need a special socket?
