Heres an PDF file on checking the 02 sensor hope this helps you out. B)

o2sensor_check.pdf

I would reset the code and drive it, then hopefully a secondary code comes up....Probably the Air/fuel sensors going bad.....

Thanks for the info, I thought about replacing O2 sensors but they are pricey. Should I do the front one first, being it is easier to get to? Anyone ever try cleaning the O2 sensors? Can it be done?

I would reset the code and drive it. why put more money into it until you know that part needs replacing. You can test the o2 sensors and see if they are working. good luck.

Yes the oil pan can be romoved without the engine having to be removed. The bolts I believe are 10MM about 12 or more. I have a PDF file on the engine if you need it, which sounds like you might. Just Pm me and I'll get it to you. Good luck

Heres a pdf file that will help you out. If you neede any other files just PM me I have a bunch for the RX B)

I know the 99-00 screens were modified for the 01-03 years with a brighter and clearer display. I wonder if an 01-03 screen would be a direct replacement to yours?

Stupid question, but is your dimmer switch turned all the way up? The dimmer switch is located on the gauge cluster bezel to the left. Just rotate it clockwise until it clicks.

Yes the dimmer switch is all the way up. It used to be bright but just isnt anymore.

The 99 has its own brightness button on the unit right under the cd and clock buttons B)

day/night mode is still affected by the dimmer.

Thanks everyone...but the brightness button will not bring it brighter, but will take it dimmer if I turn it down...I'll try cleaning the connectors as up above mentioned..any help on removing the screen?

If you want PM me and Ill send you a pdf file on removing the wood trim and the unit B)

I am looking for a good repair manual for a 2000 rx300 I need to change my timing belt & the dealer said I have to remove the dash to replace the evaporator. They wanted $1800 just for the evaporator (parts & labor)

Your little man will be alright. I know its hard to see your little one in a way that you have no control over, Im a father of three 2 girls and 1 boy. 11, 7 3 You have my prayers. All I can say is Faith.

At the risk of asking the obvious question, you are checking the ATF level with the motor running, aren't you?? Otherwise, I'm having a problem with a missing 1.5 quarts but if it shows full with the system up to operating temperature and the engine running, it's full.

Yep, checking witth the engine up and running. I dont totally understand 3 to 3 1/4 out of the drain, when I pull the pan it had around 1/4 more and filter 1/4 to 1/2 qt ,more and the transfer case around 1 qt. I'll drive it for a little more and check it again

I would drive it or at least 20 minutes to make sure the fluid has reached normal operating temperature, park on a level surface and check again per manual instructions. It it was still showing full or above I would check with a transmission shop. If 4 1/2 came out then 4 1/2 should be put back.

Thanks Barry, that was my thought also.

Ok Heres my solution, 1999 Rx 300 with 151K I did my transmission fluid change, Transfer case and installed a new filter, job easy. 4 1/2 qts came out. Put when I was refilling at 3 qts it was above the cold line???? Started the car and went though the gears, check it, drove the car about 10 mins, check it again, move up alittle not much. So here my $1000.00 question, should I repalce the 4.5 qts that came out????? Thanks

Looking to buy a new set of tires for my 1999 RX300. I was wondering if an 235/65/16 would work, or will they rub on the rear strut. I believe they are the same ratios as the 225/70/16. Thanks for your time on this.

Thanks

Jeff :D

Jeff:

I have 235P65R16 on my 99' RX300. You would not have any problem with the rear struts. I brought GoodYear Fortera Triple Tred. It cost me around $600 back then from Discounted Tires. Now, it's around $800-900. The wider tires actually give the car a lot better traction.

Thanks for the info. Im looking into getting the toyo Versado.

Hi everyone, for the last couple of days I have noticed that the temperture gauge is runnung up to the second line on the gauge, usually reads sightly under the first one, just wondering if this is a sign the thermostat is going???? Thanks for your help on this. All fulid levels are good

Thanks

hi all...

i keep getting an error code 0125

so far i replaced the thermostat

the ect sensor

and filled back with antifreeze

error keeps poping up

next step is the o2 sensor

as it could be that or a leaking exhaust (tried that for a little bit but it doesn't seem to leak)

i can't find bank 1,2 sensor 1

actually after searching i find only two sensors

one on bank one by the firewall and one on bank two by the radiator.

any tips... hints?

Looks like the document Jeff was trying to upload didn't show up. Maybe this will work. Bank one sensor 2 is located between the muffler and the cat converter. To test the sensor, you must remove the drivers seat to get to the wire harness connection. Good luck!

Thanks Joe for having my back.

Jeff

Heres a pdf file that might help you with you search. The sensors are located onne on the front exhaust, the other is on the back side by the firewall on the exhaust, third one under the drivers seat on the cat. hope this helps you out. ifyou didnt get the file pm and ill email to you.

Jeff :)

Hi-

I've got an 04 RX330 and I just found out my 3rd child is on the way. Currently have a booster seat and a convertible seat in the rear of my car.

Am I going to be able to fit an infant seat back there too? Looks pretty cramped.

Thanks

First congrats, Three little ones change your world. Three seats fitted in my RX300. Put the booster in the middle, get ready dont touch me, thats mine.

Jeff

I haves an pdf file that will help you in your travels. Good Luck. Just pm me with your emaiul address

Hello,

I have been staying up everynight reading as much as I can about the RX300. According to many reliable sources, it's very reliable. But after reading about the transmissions problems and "sludging" issues I'm having second thoughts. My wife and I have our first child on the way and want something safe and reliable. There isn't a lot of selection where we live, in fact, there's only 4 for sale in British Columbia. I've found one (2000 RX300 168,000 kms) that looks to be in excellent condition (service records, etc). If the owner accepts my offer ($13,000 CAN) im going to have the valve cover pulled and the transmission pan dropped for inspection before purchasing.

Would it be smarter to avoid this vehicle all together? Maybe get a 2002 Toyota Highlander instead? After everything people say about Lexus reliability, I'm shocked to hear about the horror stories.

Thoughts?

TMR- What does $13k in Canadian convert to in USD? That seems like a ton to much money to me for an '00 RX, even though it won't be that much in USD. I have to say, every time I drive my DIL's to work on it, I am not impressed for a car (truck?) that ran right at $40k (maybe more) new. They bought it at a Toyota wholesale auction as a lease return 2& 1/2 yrs old with 32k mi for $26k. It is not the worlds most quiet or smooth car for that kind of money. My wife's Toyota Camry ('02) at 7 &1/2 yrs old is still a dream to drive and you can virtually whisper in it at 80MPH and be heard. (we drove 900+ mi. home in one day from northern Oregon to So. Cal. because it didn't beat you up in the process). I'm not sure the RX (being technically a truck) was ever like that. I'm sure that I could find something that would please me (even in an SUV) more than that for that much money, but that's only one mans opinion. Good luck!

Supply and demand. Where I live, 2002 RX300s go for 20k. Everything just costs more. 13k CAN is about 11k US. It just had a timing belt and new brakes installed, about 3k in receipts from 2 months ago.

I own a 1999 rx300 with 147,000 miles. I have had no problems with the transmission, no oil problems, I change my oil every 3000 miles. It gets about 300 miles to the tank, and thats 90% city driving, not bad for a 10 year car. I say if you treat it nice it will take care of you. I say GO FOR IT.

White smoke is usually a sign that you're burning water... head gasket, cracked head or block. There are probably some less ominous explanations. Look for water in the oil or vice versa. Usually streaks of gray on the dipstick and also on the inside of your the oil filler cap. Once it's cool. you can look in the rad filler tank. You might see oil floating in the water, smell exhaust and the cap might pop off a bitt. Use all brecaution when you remove the cap.

Regards, PK

Thanks PK

I just check the items you suggested. The coolant looks good, No signs of oil. I mark the res tank yesterday And just checked it, I only drove 15 miles today. The engine is cool and its at the same mark, right at the top of the Denso logo. The oil looks good too. should I go ahead and drain and replace the oil? If you have any other ideas Im all ears. Thanks again for the reply

Jeff

Hello,

I have read the threads on the white smoke issues. Heres some data on the RX 143,000 miles runs great, mileage is good around 18 mpg in the city. About a month ago just replace both o2 sensors, I change the oil every 3000 miles, just did it on Wednesday of this week, In 3000 miles I consumed aboout 1/2 to 3/4 qt of oil, not to bad for a 1999 with 143k on it. But when I start out yesterday I got about 5 seconds of a very light white smoke, and a little gas smell to. I have read it might be the ECM??? I know the first thing to done is ask for help :) I check the pvc valve and gets good, air goes though it and it makes a little rattle noise. So where do I start looking or do. Do I put some injector cleaner in. I hope you guys will help me out on this problem. Thanks again

Jeff

If you have an ohnmeter you can test them. here is a file to shoow you how. good luck hope this helps your searcho2sensor_check.pdf

Hello all

I realize this is an old thread but the clicking in my '01 is driving me bonkers. Does anyone have a pictoral breakdown of the area behind the glovebox concerned with this repair. I had a pdf of the shop manual but I think that was several hard drives ago :)

Hello,

I have a question to ask. I pull out the front oxygen sensor and it has Denso part # 480467-48010, than I pull out the next one and it has Denso Part # 89467-48011, Are these two different Parts I thought the two manifold oxygen sensors were the same part. Lexus # 234-9009. By the way 1999 RX300. Thanks for your help on this.

Thanks

Jeff :D

Supposed to be the same: Toyota part 89467-48011 Denso part 234-9009. The one downstream from the CAT is the different one.

Thank you Blueridge

Thats way I cracked the manifold, the wrong part was in there. I pulled the bottom one and that one was the one with part # 89467-48011. The sensor just didnt want to move Top one. thanks for your time
