Oxygen sensors on a 1989 Toyota SR5 and located near the catalytic converter. The sensors read the emissions from the vehicle so the ECU knows ho much fuel to run in the engine.
The 2004 Toyota Matrix typically has two oxygen sensors: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). These sensors monitor the oxygen levels in the exhaust to help manage fuel efficiency and emissions. Depending on the engine type and configuration, the number may vary slightly, but two is standard for most models.
The oxygen sensors on a 2004 Toyota Corolla are located within the exhaust manifold. They constantly monitor oxygen levels in the exhaust and allow the engine to make adjustments accordingly.
air fuel ratio sensors are in the exhaust-they are like oxygen sensors but work differently
You have two oxygen sensors in Toyota Rav4, One before the catalytic converter and another after.
== == 1996 Corolla's have two oxygen sensors. The first sensor, is pre catalytic converter. It is located on the exhaust manifold. The second sensor is post catalytic converter.
In the manifolds - sometimes difficult to get at.

There are two of them.
The oxygen sensors are located in the exhaust pipes.
