I have a 1997 and a 1998 tacoma and I had to change that same sensor on both of them so that it can pass smog and on both of the cars they were on the exhaust right after the catalic converter. It is bolted down into the pipe (Just so you know, it was a pain to take of. I had to take out of both the exhausts just to get to the sensor).

It has 2 one for air in and one for air out
According to the Haynes manual for 98 Toyota tacoma, and a mechanic i just visited, two. One on each side of catalytic converter. correction, there are two sensors, the first is an air fuel ratio sensor, and the second is the oxegen sensor. i know cause i had to replace both of them. opie909
On a V-6 Toyota Tacoma bank 2 is on the driver side.
2, both are in the exhaust system .I am told the rear one usually is the one that need to be replaced . local Toyota dealer tells me they hardly ever replace the front one.
The 1985 Toyota Corolla has one.

You have two oxygen sensors in Toyota Rav4, One before the catalytic converter and another after.
The 1988 Toyota oxygen sensor is located on the air cleaner housing. You will find the sensor, on the back side of the housing.
I found some good reference info on this topic at: http://www.4crawler.com/4x4/O2SensorWireColors.html Accordingly the sensor wire colors for Toyota O2 sensors (from the sensor to the plug) would be as follows Blue = Sensor + White = Sensor - Black = Heater Black = Heater
