My SR-5 has only one oxy sensor. It is located just forward of the Cat converter on the exhaust system. It has two metric nuts holding it in place The Bosch oxy sensor was $100 or so... At the same time I replaced my Cat converter and Muffler. The Cat had over-heated several times and ruined all of that stuff all in all pretty easy fix!

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.

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.

It depends on number of cylinders the engine has. 4 cylinder engine has 2 oxygen sensors. V6 has at least 3.

air fuel ratio sensors are in the exhaust-they are like oxygen sensors but work differently

I was told by the local AAMCO guy that when I went to Mexico with my 4Runner that the gas there possibly damaged my oxygen sensors.

Soldering will be required to install the universal oxygen sensors. Specifically you'll need to first cut the old sensor off on the main wiring. Then one needs to solder the universal sensor onto that existing wiring.

Most oxygen sensors are located on the exhaust manifold or just after the manifold on the exhaust pipe(s). Your truck probably has two oxygen sensors, one on each side.

== == 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.

User Avatar

Oxygen sensors are located on the exhaust manifold between the engine and the catalytic converter. If you have a V6 model then it will be after the place where the 2 sides come together. If your not sure what it looks like go to a web site for a local parts store and put in the information for your vehicle. They usually have a picture of the part.
