bravolad:


Thank you so very immensely.

lomomike:


Bro, I just had to get my tyre loosen so as to show you the auto levelling headlamp sensor. In my own lexus in order to let you see how it is. Notice where that black hand points towards.

Right rear passenger side if you're looking at the car from behind it.

Emperoh:
my high idle speed still persists oo. . . . . . . 1000 - 1100 rpm

What should i be looking at?

lomomike:


Intake, throttle body, MAF/MAP, ECU ect.
When last did you change your air filter?
A scan will reveal a lot; do it pls.

Emperoh:


I am reading somewhere that this will normally happen after a plug change. Don't know how true.
But mine started after the plugs were swapped with new ones!

lomomike:


Yes, it could also happen.
Did you use OEM recommended spark plugs?

Wrong grade of oil can cause it to also read high rpm low quality fuel can also set off such.

Emperoh:


I used genuine Toyota Plugs and the Mobil Semi synthetic 5w30 oil

kakameks:
guy am still getting 13.3 mpg on my 2004 RX 330, i am gonna scan the car to see if any code rears it ugly head. (No check engine light)

by the way how much is oxygen sensor both banks and also the mass air flow meter? there is a school of thought that suggested a "lazy" oxygen sensor can report a rich mix as lean to the engine ecu while not triggering any codes.

just need to get a good engine/tranny/airbag scanner first.

kakameks:
already checked the air filter, it was still fine though i dusted it before putting it back.

any idea on the cost of the sensors? both oxygen sensors and air flow meter? pls new ones.

kakameks:
just did a scan, there was no code what so ever. Also ran a test of the sensors the nice guy that did the scan (free by the way) said that my Lt bank 2 sensor is not ok.

He did a drive test and the percentage that the particular sensor displayed was 0% both while the car was idle and in motion. he said that when the car is in motion the reading should change. The other sensor's reading were ok by him, it was in the range of 0.5 or something.

So the theory of "lazy" sensors not flashing a code is true.

So Now Oga Mike, any idea how much the lower and upper bank sensors are?

ladon1:
You can check your fast idle valve. It may need a little adjustment. The adjustment can also be done via the throtle cable. Any of these two will bring down the idle speed to about 800/900 rpm

kakameks:
The actual screen read LT Fuel Train B2 or LTFT B2.
My brakes are not binding
oil is fine
I will look into the plug issue but i dont think that is it.bl

kakameks:
I just popped into a filling station to fill my tank, which was at 1/4 full ( lowest level since i got the ride) after the fill a joined the road with some brisk driving and noticed my mpg jump from 12.2 to 14.1 to 15.5 to 16.6mpg!

I watched my driving till i got home, puzzled about the whole incident. So decided to peek at the O2 sensor to see it for myself and when i got undet the car i discovered a hole (size of a marble ball) on the exhaust muffler. This came with the car from america so i went to fix it and too it out for a highway test.

Using the cruse control at 100km/h, i got a mileage of 22.9mpg!!! I could have gone higher. And on getting back to town it came down to 20.3mpg even after 2 stops.

Will do a manual check of the mpg again to see the difference.

LEARNING POINTS OR SUSPECTED SOLUTION
1. The low fuel gauge may have triggered some thing.
2. It may just be a case of bad fuel, but i dont this is the case.
3. The O2 sensor may have been clogged by carbon deposit from too much rich mix exhaust gasses and the hard driving i did after getting fuel cleared it to function properly.
4. The leaky exhaust was not helping either.

well hope this long write up helps for those having similar issues. Will observe and update if any change occur.

Emperoh:
Back to Abuja and back to my ES330. . . . . got in from Kano at about 5pm. The first thing i did was to disconnect my battery head, even before i went into my apartment.

15 minutes later, i had unpacked and was about to get into town. I reconnected the battery terminal and started the car. A little hesitation but on a second crank, it came to life!!

Hovered around 900rpm at idle, but cold engine- (down from 1000rpm at idle after the plug change). This gave me some hope.

Drove off into town. By the time i got to Maitama, and parked, rpm was back to normal- 750 - 800.

So i think the battery head disconnection did the magic. I am wondering if this should be the procedure once there's a plug change?

On another issue, my xmas lights are are back!! P2241 this time.
I am waiting to see if the P0430 will come back. if it doesn't after 300 km, i will look for a new sensor for A/F Sensor B2,S1
Or Lomo wetin you think?

Also got a U0126, when i scanned my ABS. Not throwing any CEL but i am wondering where to start on this one now!??

lomomike:



Okay I'm really bad about this random codes being thrown up.
U0126 - Loss of Communication With Steering Angle Sensor Module. (Yaw sensor issue)
Did you tamper with your steering or did you do an alignment?


Reset the code and do some driving again before scanning so as to determine the issue.

(Abeg no go express or where people gather plenty or high risk zone when driving with a car having Yaw Sensor issue).

If it comes back which I don't pray for, you'll have to do a Zero point calibration for your yaw rate sensor be reprogrammed. It needs special tools and a tech stream scan tool (toyota/lexus own recommended diagnostic tool).


EDITED: I found an online resource form a site which I get some good knowledge, because I'm in a good mood I'll share it.
Here is the resource link.

Shoot me an email to send you a TSB when I wake up.

I'm off to bed

Now you scare me bros!

What's Yaw Sensor? I did clear the codes. Will do another scan to see if it is still there later in the evening. Because it is not throwing a CEL.
I hope i don't get into wahala. The last alignment i did was on the 22nd of December. 4 days before then, i did change my rotors and pads. . . all 4 of them. But i didn't see the code afterwards until some days ago.

Wonder what this is now

Abeg shoot me the mail: chinedu.anarado@gmail.com

You still dey Abuja? Maybe we need to hook up if you are still around. Else when you return.

Can't wait to see your lexus

When you're coming bring your scanner my friends always love keeping my scanners. The last one I bought was in November, january another friend took it and I am scannerless

I saw this post late. Was at Army scheme this evening to barb! Kai.

Tomorrow evening after work definitely. Will give you a shout.

I hope you have no plans of rendering me scannerless?
