I did have a Master key made but I had a chip available for my Lexus Es300 2000. Here is a Website for ES300 2002 http://stores.ebay.com/1010keys/_i.html?_nkw=lexus+es300+2002+key&submit=Search&_sid=1009547818 This is the same website I used. Perhaps ask if they sell a chip for your Es300 2002 Master key replacement. Programing was easy. http://www.clublexus.com/gallery/data/500/key_prog.jpg I went to the Lexus dealer in person with my car registration, personal ID and asked them for my FCC ID code. They gave it without any problem.

This P0325 code may show up intermittently or the Service Engine light may be lit constantly. Possible Solutions Check the resistance of the knock sensor (compare it to factory specs) Check for broken/frayed wires leading to the sensor Replace the knock sensor You don't have to do everything I did but since you replaced both Knock sensors and possible wiring leading to the sensor are highly probable for code P0325 as stated by Lexis Lexus. If not corrected, you may notice drivability problems including a lack of power and perhaps some hesitation.I supposed since you will be lifting those parts out again. Clean your idle air control valve (IACV) http://us.lexusownersclub.com/forums/topic/30723-step-by-step-instructions-for-iacvidle-air-control-valveiscthrottl/

Knock Sensor If you get a code P0330 Knock Sensors ES2000-2001 Replacing two Knock Sensors. it took me 9 hours. Parts replaced: 1. Knock sensors from rockauto.com, AIRTEX Part # 5S2254 cost $105.79 2. Knock Sensor wiring harness 3. Intake gaskets 4. By-pass hose 5. Antifreeze Replaced wiring harness 82219-07010 and by-pass hose from Lexus Dealer because I didn't have the energy to go through the whole mess again. Dealer charged me $42.00 for the harness. As well change the spark plugs cause they are breeze to change with half the engine missing. I did the work myself 3 years ago with no further problem.

When removing interior door panel to change out a door mirror. The power window switch assy is pry up from the front end and not from the rear end, using a flat tip screw driver.

Jay just simply go to Lenore reply and click on the link "Oxygen Sensor", and enter year, make and model of your Lexus. After geting your Part number go to Ebay as well but make sure the product Denso would be your choice. Let us know the correction result.

Lenore was explaining what problem we were having with the oxygen sensor on this particular engine. Look at the Diagram for location of these sensors. Just buy the Denso trademark it is a Japanese product for a Japanese car.

I am not sure if this link can help you will Fueling problem, http://us.lexusownersclub.com/forums/index.php?showtopic=72483 Toysrme suggested to download the FSM, I agree. But after you wrote that " A competent repair facility dropped the tank, confirmed all lines were clear and examined all the components", found to be good. Let us know if you found the correction action for this problem. Thanks

I bought my 2000 ES300 in 2006. Since then, I have replaced (2) A/F O2 Sensors, (2) Knock Sensors, (1) Coil pack on #2 cylinder, Window regulator/motor front passenger side, IACV under throttle body, (1) top and front engine mounts and (4) shock struts (I did my own work). I had the timing belt replaced for $500.00 and replaced four tires 2x since then. The hards job I performed was the Knock Sensor, took me 8 hrs and $320.00 in parts. http://us.lexusownersclub.com/forums/index.php?showtopic=30723&hl= My wife is happy with this reliable car. She drives it everyday 40 miles per day to La Jolla, San Diego ca.

Here is a topic on Oil Control Valve and Jerking action experience by one member. I hope this link be of some help. http://us.lexusownersclub.com/forums/index.php?showtopic=68046

I am not sure if this Diagram can help where Oxygen Sensor are position but the downstream is located after the TWC.

I am not sure if this link can help you http://www.clublexus.com/forums/es300-and-es330/470652-01-es300-valve-cover-removal-for-sludge-inspection.html and here another link http://www.toyotanation.com/forum/1451694-post13.html

I am not sure if this makes any sense but the air inlet rubber hoses after the MAF could be crack. With this crack hoses will allow more air to enter the TB without the MAF sensor to measure its intake. I found this code on our forums http://us.lexusowner...71&fromsearch=1 I hope this visual check could be of some help. I replaced both AF O2 sensor because of false indication with ECU. Check the Dogbone upper mount, and what correction as stated on the link.

Here is a photo of O2 sensor Bank 2
