1989 Corolla ..1.6L there are two of them, upstream and downstream, one before the catalytic convertor and one past it. They are both in the exhaust stream in other words.

1 out of 1 people think this is helpful. .....and this is the other one. It takes a big wrench: 7/8" or 23mm .....big Crescent maybe but it's going to be tight. VERY much so so from the heat/cool so many times, try to use a good tool, if you round off the hex than pipe wrench, if it will fit in there
