my buddy had his check engine light come on and took the truck to the dealer. the dealer said it was the driver side o2 sensor mounted on the exhaust manifold. They told him 520$ to replace it and that most of the time, the heat from the exhaust will melt the 02 sensor in place and they will have to replace the manifold also. they said it could cost up to 2000$ Sounds like a load of SH@@ to me. anyone else have any opinions.

yep, there are actually 4 o2 sensors on tundras. one in front and one in back of each cat. I thought the same thing, soak the bolts and swap in a new one 100$... Shady dealer, el cajon toyota.

What a load of crap. It took me 15 minutes to replace the o2 sensor in my 4.7v8 in the Land Cruiser, and I have more crap in the way and less room to work.

The part is available for less than $100. OEM Toyota is mfg. by Denso and the Denso part is the same exact thing:

I'm a few days late so I hope he hasn't changed it already.

I changed mine Sat. 12mm socket on the back sensors and the special socket for the front. Took 15 mins on each one. Bought mine from oxygen sensors.com but Densco had them a little cheaper. If the rear sensor was on one side you should go ahead and change the other side. I paid $100.00 for each sensor on the rear and $70.00 on the front ones. I know I didn't need to change them all but with what the Toyota dealer wanted to do 1 I did 4 and still saved $200.00 dollars.
