== == 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.
I think only 1. it's located below exhaust manifold before the cat converter.
How do you change oxygen sensor in 1992 Toyota corolla? Is there a model engine 4A-FE without a oxygen sensor?
The 1985 Toyota Corolla has one.
You have two oxygen sensors in Toyota Rav4, One before the catalytic converter and another after.
under the hood
there are 4 oxygen sensors one at the rear of each exhaust manifold and one behind each catalytic converter.
In the manifolds - sometimes difficult to get at.
