This DIY works really well. The only problem at all was disconnecting the electrical connector. You really can't see it very well because it's almost flush with the edge of the dash. Just press down on a recessed arm (with a small, slotted screwdriver.

Just replaced Bank 1 Sensor 1 error. I got the sensor off of Rockauto.com for $34 shipped (came with the built in heater). Took about 2 or 3 days to ship. PB'd the heck out of it in the morning and then right before I wrenched it off. Granted this is the easiest sensor to get to, it took all of 10 minutes to do the swap. Took longer to let the PB work its way in and reset the ECU. Difficulty 1.5 out of 5.

Okay, so my first question, is how do you know which is bad, since there 4 right? I guess I could take it to lexus and pay the $138 for the diagnostics, but is there a way to find out otherwise? Also, how hard is it really to do this? I am good at alot of things, but anything having to do with the "check engine" light, well I am not always too comfortable doing. but if it's not that hard, maybe i can. Or I can buy someone a 12pk of their favorite beer in echange?? I will buy the parts of course!

I'm sure the other auto part stores may offer the same thing. Call them.
I go to Advanced Auto Parts every once in a while to make sure that the light that is on is for the same thing - my O2 sensor and not something else. It is free. Free. I started to feel guilty going there for just a reading so I buy some smelly thing. I'm sure the other auto part stores may offer the same thing. Call them.

I'd rather be able to read and reset my own codes rather than rely on the diagnostic capability of anyone at an auto parts store, free or not. Also remember why they are offering this service for free and why they are in business - they want to sell parts. So what may seem like it is in YOUR interest is actually in THEIRS.

I'm interested in these readings as well. My car isn't throwing the check engine light, but I have lost 12% in MPG all of the sudden and it has never increased. Been over 9 months now. I've tried everything else and nothing has fixed it. So if I can check Ohm readings that might eliminate the potential of buying new sensors and saving a couple hundred bucks on 4 new potentially unneeded parts...
