  1. Hi,

    I have a lexus rx300 2000 model and the keyless remotes dont lock/unlock the car.

    a.) the keyless remotes are the original that came with the vehicle

    b.) The light comes on the remote when the buttons are pressed, also has new batteries so no chance of low signal.

    c.) The car starts and locks and unlocks with the key manually.

    None of the buttons Lock/unlock/panic seem to have any effect no matter how close or far from the vehicle.

    Please help me in getting the remote to work.

    All help and ideas are greately appreciated.

    Thanks

  2. I've same issue with my 00 RX 300, How did you guys replace oxygen sensor ? Is there any step by step guide with pics, sorry I am a newbie.

    Thanks

    Well, If you are pretty sure that the oxygen sensor went bad.

    then it is very easy to replace that if u are a DIY guy.

    Unfortunately i don't have a pics to show the step by step. but can tell how i did it.

    1. i removed the driver seat 4 bolts and slid that seat back to have access to the oxygen sensor that is under the carpet off driver seat.

    2. remove the 2 nuts that fit the oxygen sensor, located under carriage and in the exhaust pipe under the driver seat side.

    3. Pry out the rubber tubing that goes to the driver seat. and not follow the same steps to replace the new Oxygen sensor.

    It took me 1 1/2 hrs to do it.. If i do it again i probably would get it done in less than 30 mins.

    pretty easy job... no need to go under the car or lift the car.

    It is more difficult to replace the Air fuel ratio sensors than oxygen sensor.

  3. I dont know if you have American Tires Stores in your locallity, but they are fair and good. The Michelin Latitude is a great tire, and yes I am one of the ones with costco problems. If your car is AWD it gets tougher with their policies if you have worn tires and need a replacement for hazard. Another great source is Tirerack.com. I have used them and they list installers in your area. I have gotten great deals, and they have consumer feedback on all of their tires with outstanding info on each tire.

    I have a 2Wheel drive. and am from Dallas, Texas area. I heard some people used 235 instead off the standard 225.. same price though.. any experiences with that

  4. Hi guys,

    My car 2000 Rx300 got broke into last night and stole GPS etc.

    They broke the front passenger glass and i need to get the replacement glass.

    Can you all give me the expert advices of where to shop and what company make glass will work with out issues.

    All help is appreciated very much.

    I am from the DFW area so any help on the shops that does the work is appreciated as well.

    Thanks Very much

  5. Hi Guys,

    I noticed the MAS Sensor O ring has some cracks in it.

    Called Lexus and they said that comes with MAFSensor only. But my MAF Sensor is good and dont have problems.

    Can you guys let me know where i can purchase just the O Ring.

    Thanks

  6. FWIW, Iridium plugs should not be gapped as you can ruin the coating on the electrode. I would check the vacuum lines and the electronic plugs on the throttle body & IACV if there is one. If you got cleaner on the chips on the TB you could have damaged the electronics. But first check those connections to be certain they are connected correctly.

    I had apply throttle body cleaner liberally on the throttle but I did not open the black cap where the connector is. How do I check that the electronics have not been damaged? Would I need to replace the spark plug since I gap them? Thanks for the help.

    KBRX330

    I have attached the picture of the part I cleaned. Are you referring to that plug on top when you say electronics or the black piece that attaches up front? Thanks.

    have u resolved the problem ?

    if so what was the problem or what did u do wrong in cleaning ? this info would be helpful, do's and don'ts, for folks trying to clean the IACV.

  7. I do know that carfax isn't the "be all end all"...just trying to get as much info as I can. The seller has an autocheck report, but there seems to be holes in it. And he has no service records. He claims the previous owner did the timing belt (along with a bunch of other stuff). So trying to find what I can as quickly as possible. Thanks.

    Any Lexus dealership can take the VIN and put it into their national service history database. That will tell you all the maintenance that they, or any other dealership, has done to the car.

    It's pretty unusual to find records like timing belt replacements in CarFax reports. Many car dealerships now require you to show proof of ownership to obtain service records. I guess maybe that's why, but it does not make much sense to me. For that reason, they probably do not provide service records to CarFax.

    Luckily, the report that the Lexus dealership will give you does not contain any of the current/previous owner's personal information, so they do not require any kind of proof of ownership/ID to get one. You can even just do it over the phone at most places.

    Well, Carfax would give you any accidents the car got involved. That also if the accident is reported and recorded by the police. Some accidents are never reported and get settled between parties, in those cases that never gets in carfax. It also gives you the number of owners of the vehicle.

    It is a first level check to make sure it is clean from accidents and then take it to a dealer to perform detailed evaluation on the car before purchase.

  8. Thanks V Much.

    I will try that. Last month or so i got CEL then i cleaned the MAF sensor with the cleaner CEL went away. It came back.

    will try again..

    Some of these codes are probably 'chain reaction' codes, meaning they are getting triggered because some other component is not functioning properly, and then !Removed! up the system. P0171 is probably one of those codes, for it means 'lean bank one'. P0141 means the O2 sensor on bank 2 is slow to respond. The other codes are saying they have circuit malfunctions. All these codes refer to an air/fuel metering issue.

    I would first try cleaning the MAF with automotive electrical spray cleaner and see if that helps your issue.

    What would really help you is to get a code scanner. Then you can clear the codes, and as soon as the CEL trips on, you can pull the code right away. That way you can get the first code(s) that shows up, which is usually the problematic code... if you continue to drive the vehicle with the CEL on and an air/fuel issue, it almost always causes additional 'chain reaction' codes to show, and those can be misleading to the root problem.

    Again, I would clean the MAF, then reset the ECU (I do it with my code reader, or you can disconnect the battery for a few moments, too). Then, when the first code pops up, scan for it. That'll point you in the right direction.

    Thanks all for the responses

    I had replaced the Oxygen Sensor and it did the trick. I had to remove the driver side seat to have access to the connector.

  9. Hi guys,

    Went to the Lexus dealership for CEL P01701, P1130 and P1150 and they gave a quote for $1200 to change

    1. Oxygen sensor

    2. two Air fuel ratio sensors.

    I thought it is waaaay tooo much and would like to see if i can do it myself.

    Here are my questions:

    1. Where are these located in the car ? Is there a step-bystep instructions of how to do it ?

    How difficult is that job.

    2. Where to Buy. (Sewel Lexus has O2 for $139 and Air Fuel ratio sensors for $206 each) factorylexparts has Air fuel ratio for $150

    Appreciate all your help

    Thanks

    lahermano- I agree with the other poster- it would be EXTREMELY unusual for all 3 of those to go bad at once- they're expensive and not like engine oil- I wouldn't change them unless they are actually BAD. How many miles on the vehicle?

    How does it run? Unless it is running really bad, I would do a little more research , you might find out you spent all that money and effort for nothing. The 1st. codes that come up don't necessarily tell the story, sometimes not at all. Hate to see your pockets turned inside out by the parts fairy and still not solve the problem. Good Luck!

    Hi,

    Thanks for the response.

    Well, The car has 114000 miles on it and the symptoms that i see are

    1. Very low gas mileage, it dropped ever since i started getting the CEL for couple of weeks, but the mileage dropped suddenly last week. I cleaned MAF meter

    2, while driving like 40 mph is all fine, and if i start accelerating then i see some jerks, possibly a misfire or something. I am still driving that, and will check more.

    all the driving is local driving about 30 miles a day.

    3. some kind of burn smell coming inside the car and also at the exhaust

    At this mileage, are these sensors to be replaced as a wear and tear parts ? or can they last more than that ? what is the usual scenario here.

    Will investigate more.

    Thanks

    I wouldn't consider them wear and tear. There are ways to test the sensors individually. I feel there is still more research that needs to be done. I would clear the codes and see what comes back up. (TC's) If the same codes come back up it still doesn't mean that it needs the 3 sensors- That would be extremely unusual. If you throw enough parts at it you may fix the problem but need a loan just to buy lunch by then. LOL

    Well,

    I cleared the codes 2 times and i still get the same codes.

    Lexus dealer told that oxygen sensor and the airfuel ratio sensors to be replaced.

    I think they just want to rip me off and may not have done proper diagnosis. They wanted $1200 to replace these.

    If i change these 3 parts it would cost only parts ($450) + labor. What a morons....

    BTW, Airfuel sensors (what lexus refers to) and the upstream oxygen sensors (front cylinder head and rear cylinder as Hynes manual refers to) are the same ?

    That is affirmative. A lot of people still refer to them as oxygen sensors and even parts books do quite a bit so it gets very confusing. The 2 on bank 1 and bank 2 (just downstream of the exhaust manifolds) are in fact AIR/FUEL RATIO SENSORS. Very much different than an oxygen sensor. The 1 that is downstream (I believe just after the cat. convertor) is in fact an OXYGEN sensor. The rear A/F ratio sensor (B1 S1) is a little tougher to get to and the oxygen sensor MAY require removing the front seat (don't remember whether dr. or pass.), or maybe not- do a search, but is not worth that kind of labor. I have changed both A/F sensors and did not feel that was bad at all. It is a little hard to release the barb that holds the rear A/F sensor plug together. Be sure and soak the threads for a couple days before you try and take them out (with a good penetrant). A lot of people don't realize you can wipe the sensors out by using a silicone gasket sealer that is not "sensor safe". Good Luck!

    thanks very much for the reply. I will check it out.

    Thanks all for the HELP!

    I finally got the problem resolved

    I just replaced the Oxygen Sensor. (downstream after the cat. convertor)

    Part purchased at sewell parts for $139 + taxes and shipping.

    I had to remove the DRIVER seat (4 bolts) to have access to the OxygenSensor connector.

    The total process took me about an hour.

    Now no CEL and car runs good.

    Thanks again
