You have two oxygen sensors in Toyota Rav4, One before the catalytic converter and another after.
It depends on number of cylinders the engine has. 4 cylinder engine has 2 oxygen sensors. V6 has at least 3.
There are 2 Oxygen sensors. One is on top of the catalytic converter called the upstream and the other is at the bottom of the catalytic converter called the downstream.
I believe there are 2 oxygen sensors that are used for air / fuel ratio and 2 oxygen sensors that are downstream from the catalytic converters and are called catalyst monitors
2, one before and one after the catalytic converter
