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.

SOURCE: How many O2 sensors on a 1997 Lexus ES 300?

according to the manual i have... it has three.... one in the exhaust manifold.... and two in the exhaust pipe..... slightly vauge on the exact location of the last two sensors... but looks like it is after the catylitic converter.

Unscrew the gas cap, wait 30 sec and screw it back on making 3 clicks/cracks. Should be ok in a day or two.

The fuel filter on the ES300 is located under the hood, on the driver's side, by the fenderwell.

SOURCE: How do I remove and replace the rear speaker in my

Hello, I have a 2000 ES300 and while the body style is different believe the newer model still has the rear deck mounted sub-woofer that you are referring to. The process of removing this speaker would start off the same as if you were going to replace the third brake light also located in this housing. Using a flathead screwdriver work your way around prying/popping up all four corners of the speaker grill covering the speaker that have the retainer clips. Once you disengage the clips work/maneuver the grill up and towards you gently and it should slide out. The bulb for the third brae light will be attached to this speaker grill, disconnect the snap wire from the bulb and you should have a clear visual of the speaker and the four bolthead screws securing it. Remove these screws and your almost home free. The next part might be slightly more difficult. If the speaker s simply connected by a clipped on wiring harness, just detach.On my 2000 ES300 i have the pioneer system(Not Nakimichi) and the 2 wires (one black, and one red) are soldered directly to the speaker. You can take a soldering iron(maybe a battery or gas powered one unless you have an inverter) and remelt the solder to remove the wires or you can elect to simply cut the wires. If you choose to cut them make sure you cut them as close as possible to the soldered joints so you have plenty of wire left to install the replacement speaker.Then install replacement either soldering or using crimp clamps and reassemble. ( Note if you simply want to add a aftermarket amplified sub-woofer you don't need to remove the sub-woofer out of the housing. You can tap into the wire leads and run it directly to the amplifier. Just cut one of the wires leading to the stock sub-woofer so it doesn't also come on and potentially blow while the radio is on. This will also prevent any bass humming when the radio is shut off but the aftermarket amplifier is still on because once one of the wires to the stock sub-woofer is disconnected or cut it breaks the circuit. Hope this helps.
