There are two O2 sensors on a '94 Lexus ES300. Both are located on the exhaust manifolds. There is one accessible from the front just to the right off-center of the engine, and one is located on the rear of the engine down low approximately centered with the engine. Hope this helps. WB
Under the intake manifold.
It just cost me $220.00
there is usally 3 o2 sensors 1 on the front of your motor looks like a spark plug sticking out and one on your exsaust and another one somewhere else look on google
That year has 2 oxygen sensors.

Stop by your local AutoZone. They will hook it up to a handheld tester and print out which oxygen sensor is failing.
The labor cost should be around $120 dollars. Hopefully you can get a couple of estimates and go with the cheapest.
