Question about 2002 Lexus ES 300
I want to change my o2 sensors where are they located and how many are there.
There is one before each catalytic converter (usually up right near the exhaust manifolds), and one after each cat (or if you have a Y-pipe exhaust that brings the two sides together to one pipe and one converter, then there's one after that single converter). Why do you want to change them? Have you gotten failure codes or are you having poor gas mileage? Or have they just been in there a long time? They're usually good for about 60k miles, although of course they can fail early. Usually the symptoms are poor fuel economy, running rich (seen by black smoke out the tailpipes and some rough idling, as well as blackened spark plugs), or fault codes dealing with system-lean or system-rich descriptions. Those symptoms are indicative of bad primary O2 sensors (the ones closest to the engine). If your secondary sensor(s) are failing (the post-cat sensor or sensors) you'll trip a check-engine light warning you of poor catalytic converter efficiency.
