1997 and earlier is linkage throttle
1998 onwards is electronic - basically the mark 4 and onwards
the electronics make the throttle very responsive and make the car feel light
Thank you, this answers my question perfectly.
Generally I have always been rather skeptical about electronic throttle controls on cars, because of how it may introduce a new component for failure.
Has it been known for these to ever fail for anybody?
Edit: And if it fails, how much do the replacement parts cost?

Im wondering if anyone knows if the gas pedal on the LS400 has a mechanical cable linkage or if it is drive by wire??? Does anyone know?

Thanks man that answers a bunch of my questions that I had. :)

@ReCat - 125mph. It sat at 100+mph for about five hours one day - if my wife was driving she more comfortable at around 100mph but I would tend to be in the 120mph region. It still averaged 23.5mpg that day which I thought was pretty impressive.
Thanks. I understand you have a 1993? Is that the top speed you achieved, or is it the top speed you were comfortable driving with?

Hello guys
I have one more question about the british LS400 as compared to the american counterpart.
The newer models after 1995 have an LCD screen below the speedo which displays your MPG. Is this MPG specifically british MPG, or american MPG?
As I understand 25 american MPG equates to 30 british MPG. This has been a lingering question and I would appreciate it if I could find an answer.
Thanks

What was the highest speed you achieved while driving this lexus in the Autobahn?

Nice to see you have the roadtrip traveling spirit in you. :) I have always thought to be a very nice car to road trip long distances with, good to see others agree!

Hello, yes I am aware of the rules. Did i break any of them?
.... I don't know the answer to your question but as a driver of Ls400 for some 15 years I really couldn't think of a better car to drive ............. and if it doesn't have an OBD2 port ? would that deter you from buying one of the best cars in the UK ??

Maybe not, but it has been a lingering question that has been bothering me because I haven't really been able to find an answer to it. :) Furthermore one of the things I like to do to cars I am inspecting before buying is put an OBD2 scanner on them and read any codes that haven't yet reached the threshold to trigger the check engine light.
My 1998 LS400 has an OBD2 port (down below the steering wheel).
However, I bought a cheap Bluetooth OBD2 dongle and can't get my phone or tablet to talk to it. Whether this is the fault of the car (non-standard OBD2 in 1998?) or the dongle (cheap and useless?) I can't be sure!
Good to know! Have you ever tried the dongle on another car? I hear they only work through the CAN Bus or something.
The ls400 is a very complex car when it comes to reading faults.
The number of ECUs is too much for generic code readers. However, you can get Toyota TIS Techstream mini VCi rather cheap on ebay and that works perfectly.
Alternatively you can get the codes using the TCCS method. Bridging 2 pins on the connector and read the codes on the dash. On the earlier models this is achieved by counting the times a light flashes, on the mk4 you can get the actual codes displayed on the multi info display by pressing the 'function' button.
Wow! Interesting! I heard that there was a light flashing thing you could do, but I never knew that they let you view the actual codes on the display on the newer models.
Do you know if the Toyota TIS Techstream mini VCi device you mentioned will work on pre-1996 lexus cars?

Hello, I have a question that maybe some LS400 owners here could help me tackle.
I want to know if the LS400 in the UK has OBD2 ports on it? I know that in the USA OBD2 was made mandatory by 1997, but this doesn't apply for europe. I also heard that the LS400 in the USA was fitted with OBD2 ports even before it was mandatory, some models from 1993 even having the OBD2 ports in it. My question is, because OBD2 in england was not made mandatory until 2004(?) does the lexus LS400 in england contain an OBD2 port?? and if so in what year did they begin using it??
I am interested in buying one since it is one of the few cars that have the "american spirit" in them that i can purchase in europe (yes, i know lexus is japanese, it is just a feeling) plus I would like to get something familiar as I used to drive one of these when I lived in the states.
Thank you.

What Years Of The Ls400 Are Drive-By-Wire?

Interesting! That is indeed slightly worrying.
I imagined so, Surely an electronic pedal wouldn't ruin lexus's good track record for reliability. I am highly considering buying myself an LS400, which generation would you reccomend? Mechanical linkage or the newer electrical ones?
