P0171 Code on 00 RX300, repetitive issues / Limp Mode
I know there are multiple threads on the subject and some of my issues are similar, but the dam code keeps popping back and putting me in limp mode so I thought I'd start a new one specific to my issue so that it might benefit myself and others down the line.
Bought an 00 RX300 with 120K miles, had a MAF sensor engine light on, at the time I had no idea it was in limp mode because I just drove it around the neighborhood (ya, I won't do that again), negiotiated the price down due to the codes so at the time I think I got a fair price, I didn't notice it was in limp mode until the 100 mile drive home on the highway and the saga began. Seller told me the CEL had been on for over a year but car ran fine so he ignored it (that was my first warning sign I guess)
Had mechanic replace the MAF sensor, and the 02 sensor (I believe the one in the back of the engine compartment)
There are two others? One near the Radiator and another one underneath near the CAT?
I'm getting ready to buy one (or two) off Amazon But I don't want to buy the wrong parts, and throw money around.
Denso 234-9009 Oxygen Sensor ? Is this correct?
Amazon under $100 shipped, cheaper than the mechanic's prices of $170, he can install for me pretty fast.
Yesterday after we did the MAF, and the first 02 sensor, Air filter, and fixed a small exhaust leak) It ran perfect for about 30 miles, I was all giddy on the drive home, then just before I got home of course the light came back on and she went back into limp mode... grrrr

P0171 system too lean Bank 1

Mechanic thinks maybe one of the cat's are clogged up, and those don't seem that expensive at least on Fleabay unless Its recommended that I avoid using the $120 versions.
Am I underestimating the cost/usability of those aftermarket cats?
Am I underestimating the complexity of having my exhaust guy install one? < I haven't asked him about this
I like the car and i'd like to hold onto it for some time, but I can't deal with this limp mode issue, it absolutely has to be fixed.
(fortunately I decided to hold onto my old car for a week while I got my new RX all spiffy, so I'll be holding onto that for a little while longer)
Suggestions on where I should proceed from this point?

semi side note:
I already ordered a cheap ebay used scanner to check codes myself to avoid stops at the mechanic or autozone in the future for silly stuff
then I got to reading about these real time bluetooth scanners, I didn't even know these scanners existed.
ordered one of those too and will do the torque app.

I would replace the remaining two sensors. The O2 sensor is under the car, after the two cats come together. The two sensors on each exhaust bank work as Air Fuel sensors (AF). the computer uses these along with the MAF to advance or retard the timing of the engine.
I had some of the same errors you did, changed all these sensors and STILL had the problems. Root cause was the oil control valves, one of mine was bad. The OCVs job is to control the flow of oil to the upper camshafts which can advance or retard their timing. The sensors tell the computer how to control the valves, but the valves themselves have no feedback loop to the computer for it to record an error condition. So if they aren't working properly, the problem keeps reporting as the other sensors being out of spec. I would just replace the two OCVs, they aren't that expensive. I bought mine form a Toyota dealership, same part just cheaper than Lexus dealership. Look at my other posts on this subject.

Been dealing with P0171 myself for quite some time now(about 1200 miles or so for me)... I have cleaned maf sensor several times with crc cleaner, I have replaced both ocv's with oem toyota(bank 2 about 10k miles ago and bank 1 was about 4k miles ago) so they are fine... Pulled both ocv screens to clean them out but they were fine... Swapped a/f sensors between bank 1 & 2... Added lots of wasteful fuel system cleaners... Recently pulled rear plugs and they were a bit loose so I cleanes them and torqued them down a little more had also pulled bank 2 plugs which were also cleaned and reused... It was running fine for about 120 miles since I had cleaned the rear plugs then just recently P0171 came back...
My next attempt at getting to the bottom of my issues is to pull valve covers to replace seals and gaskets so that I can get new plugs in to see what happens... Then if after new plugs don't do anything I am going to pull injectors and either rebuild them or replace with rebuilt...

no unfortunately I don't have an original printout so I don't have a before/after comparison on the codes.
there are only 2 other 02 sensors if I recall correctly, and a couple hundred + reasonable labor isn't' going to break my heart but no sense in replacing a sensor if its not the sensor causing the problem but rather detecting one correctly. right ?

I have P0171 and P0420. The car is not going into limp mode with these. The knock sensor code will do it though.
I don't have a consolidated list of which codes will and will not do it
Clear the codes and see what pops first.

is your P0171 accompanied by a P1130 or P1150?
Even if it is not I'd venture to bet you'd fix your problem by replacing all three sensors (2 A/F sensors and 1 O2 sensor) (or in your case 2 since you've already replaced one). They are cheap (as far as car fixes go), and will very likely fix the problem. It's so easy and where Id start.., plus if it doesn't fix the problem you can likely return the sensors.

Do you have oil wasting syndrome? That will tell me a lot.

Sorry Guys for the long delay,
(I hate when people do this, I do a lot of forum support on 2 stroke seadoo's and get frustrated when the OP disappears, my bad)
went out of town on a 5 day drinking/boating vacation with the boys, limited internet at best
I took it to another guy that a friend recommended.
1) I have no idea what oil wasting syndrome is, but I haven't driven it enough to know if its burning oil, i'm still driving my old car as a daily driver until I could address the current issues..
cleared the codes, new guy didn't give me the numbers but wrote up what he found.
( I can run them once again tomorrow, still waiting for my scanner to arrive in the mail lol)
02 Sensor, Bank 2 Sensor 1
knock sensor Bank 2
There is an aftermarket CAT installed
Back Bank 1 Sensor 1 not changing voltage
Fuel trim out of Parameter (he said 58 and it should be 10?) < seems dramatic
This guy also detected a slight noise in the timing belt area, Idler pulley or tensioner pulley maybe, he set that aside due to the other issues.
Basically guy #2 suggested these next steps.
replace the other 02 sensors (relatively cheap)
if no fix, consider replacing the first sensor just in case it went bad 30 miles after installing it (it happens right? just not that often) that should cost me nothing.
other possible excuse he thought was maybe the guy that welded the CAT didn't disconnect the battery and shorted the ECU which would maybe cause the 02 to fail again?.
I can order two denso 02's for about 190 shipped, and labor would be minimal, the other two sensors are easy to get to.
at this point i'm willing to toss another $250 at this for the 02's and see what happens.
does this info provide any insight ?

I just read your write-up on that in the knock sensor thread, as I mentioned, not having enough miles under this to know if this is the issue to be honest.
most definitely bookmarked it that's for dam sure, but that project seems over my head, the knock sensor splice is within my capabilities.
i'm thinking that it might make sense to replace the other two 02's, revisit the original third (first) 02 if that fails, then scratch my head some more before I take other steps.
in the meantime I threw some fuel treatment in there with a full tank and i'll put some miles on it.

semi update.
replaced the front 02 sensor which improved drivability and removed that rich fuel smell I was getting.
however the mechanic is still somewhat pessimistic because the front 02 sensor was totally dead, and appears to have been dead for some time due to PO ignoring the CEL which has caused problems down the line, possibly including the Cat's, He also detected a slight bearing noise near the belt tensioner (belt & water pump were done 20K miles ago but he doesn't like the sound so that means more labor hours to address. It was a reminder that when you ignore fuel issues, especially for a long enough period then bad things happen.
In the meantime, car runs smoother, but the knock sensor is throwing the CEL code and still putting me in limp mode.
before I consider the knock sensor hack, or just cutting my losses and selling the car i'm going to sleep on this.
Knock sensor & related (parts are really not a ball buster but the labor hours are, ugh)
If the knock sensor is going to be done and the timing belt issue explored its a lot of labor costs and i'm not confident enough in my DIY skills to tackle it. ( a friend of mine has a hubby that is looking for side work, he's a 20 yr mechanic and a tranny specialist so i'm going to have a talk with him over the weekend) I have a spare vehicle so a qualified guy doing this on the side just might make it reasonable enough and he can do it at his convenience.
my concern is that in addition to all this if the cat(s) are now bad due to long term neglect then i'm going to be visiting another shop to address that, and knowing my luck the dam tranny will pop 6 months later.
I'll re-run my codes one more time tonight when I get home, at least now the list of codes is getting shorter

Thank you for the updates.
Not knowing the prior history of the vehicle, it is very difficult to predict what could be the next set of trouble and is it really worth spending more than the current worth of the vehicle. We dont know the odds ... so go with your gut call. wish you luck.
