Where is my O2 sensor?

'92, 3VZ-E, 4X4. Need to replace my O2 sensor but not sure where it is. Just bought truck, need guidance. Thanks a lot for any help.

You need to go down to Pep Boys and go buy yourself a repair manual
for the year and type of vehicle you' re driving.I myself got the "HANES"
there is also the "CHILTONS" repair manual

I agree. When you buy a vehicle you're not familiar with, always buy a manual for it. I know that the chiltons is easy to read and pretty thorough. Not sure about the six cylinder, but on my 22r the o2 sensor is right at the exhaust manifold.

Yeah, alright, good call.... buy the manual. I used to own an '85 Tercel and although there are similarities, it's a different animal. Thanks for your advice.
