O2 Sensor?

[Little Buddy]

I have a 2006 es 330(65000 miles) with trouble code with the following

p2195

o2/ sensor signal

stuck lean

bank 1

sensor 1

can anyone offer a tip for finding/replacing this sensor? Also it came on 2 days after new snow tires. Probally just a coincidence?

thanks in advance

I'm more familiar with the 1994-07 es 300's, but believe the "bank 1" location is buried on the back side of the engine, on the exhaust manifold. Replacements sensors are typically expensive at Lexus/Toyota dealerships (> $100), less so at auto parts stores (<$100) like advance or autozone. If you're handy with a soldering gun, you can by a universal type and splice on the connector from the old one; this might only cost about $35-50, easy to find on ebay. On the older es 300's, getting to it is tricky, requiring taking off a good bit of the intake. Not sure what labor charges are but I bet at least 2 hrs, unless accessability was greatly improved in the 2000's.
