1990 Camry V6 - oxygen sensor

[danielbot]

I have a new oxygen sensor, but I can't install it, because I don't know where the oxygen sensor is on the engine. I've done research in auto repair manuals, and determined that it is under the exhust manifold, but when I look at my engine, I can't find it.

What I was hoping for, is a very clear photograph of where this part is located on the engine.

The normal model has one sensor. It's located on the rear exhaust manifold. Basically between the engine and the firewall. Get underneath the car and have a look up the back.
If yours is a Cali spec car, it will have another sensor, which is located after the cat converter. down the exhaust pipe.

The easiest way to locate it is to remove the front passenger tire, and look through the hole in the frame located just rear of the strut. You can see the O2 sensor sticking-out of the downpipe...just unclip the harness, remove the two lock-nuts, and put the new sensor on. Try to get a new gasket as well, the tend to chuff (leak exhaust). Good luck!
