Replying to: eanders (Oct 15, 2009 6:43 am) 1. If they're charging you $400, go somewhere else. Its a simple job and doesn't take any Toyota-specific knowledge or tool. 2. There are only 3 on the V6, despite what the manual says. Bank 1 is the rear exhaust manifold, Bank 2 is in the front manifold, and the third (post cat) is after the converter just before the muffler. 3. Please see posts 4360 and 4362 in the Maintenance and Repair forum. 4. There is no recall for O2 sensors. Someone posted a general comment that there was, but was not able to provide any detail.

My son changed my oil in my 2005 Highlander, but I have forgotten how to get the light off. Can someone please tell me?

Replying to: jrfiero (Oct 16, 2009 5:01 am) Back in September I had an O2 light also. The sensor, with a discount, cost me $250.00 at the Toyota dealership. Two days ago I got another light. I hope it's on the other (there are 2) bank. In any case, I ordered the sensor, a Bosch (OE) #1521 from Amazon for $109.00. I like the price. Since it is also the front sensor, I'll probably try to replace it myself. It's supposed to be an easy job? I'll need a special wrench and 'anti-seize' stuff for the treads.   Oh yes, and this is relevant. The time-to-change interval on these sensors is 100,000 miles. I had my first failure right after 100k and this second one at 105k. So, I suppose I shouldn't be surprised.
