Thanks John, I'll look into it! 👍🏼

Thank you, Sami! If I can't get ahold of any sensors (the ebay seller doesn't ship to Italy), I might go this route. Now I know where to look.

Thank you all, your input is much appreciated.

He's good with electronics/computers and works with many cars, from what I know. Not provocative, just asking: does someone have to know where every ECU of every model/make is, in order to be good at working with them?

Hey all, I've been trying to get ahold of some TPMS sensors for my 2006 GS 450h. Anyone know the part number for a more accurate search? Found some programmable AUTEL ones, but the ECU via Techstream doesn't accept the code, as it apparently needs TPMS's that are compatible for my model. So, considering my ECU doesn't even show me the pressure values, just alerts me when they're too low, I was thinking of disabling the TMPS check altogether from the ECU, which is gonna be cheaper than hunting for compatible TPMS. I have someone that can do that for me, but we don't know where the ECU is in this model anyone have a clue? Thoughts or advice in case you have other suggestions?

That's very helpful, thanks John!

Thanks for this, but I'm afraid it's for a later model, not the 2006 one.

Hey all, I'd like a digital copy of my 2006 GS 450h. I have the paper version in Italian, but would like a digital version in English or Italian. Anybody have one? I looked online and they all start from 2007. Thanks

Hey all, I need to replace the 4 TPMS's for my GS 450h. I'm based in Italy and I believe the car was originally sold here. Do you know if there's any way to find out with certainty what frequency they use without without having access to the ECU or any other electronic device atm? Also, would dual frequency TPMS sensors work just as good?

I suspect I might need Techstream for that too! 😂

Thank you so much for this clarification, John. This makes so much more sense now! Unfortunately I don't have access to a Techstream atm and the only option seems to be the Lexus dealership, which will 9/10 charge me an arm and a leg for the work. IF they want to do the work, because often they don't do the encoding if you haven't purchased the spare from them. Also, being mine a Gen 3, I'm also aware that not every version of Techstream works with this model and I might have to get ahold of an older version + a cable + a Win laptop. Not sure which option is quicker/cheaper/non-stressful. Just keeping the alarm permanently on is not off the table!

My tyre fitter told me the ECU should recognize the sensor automatically, but from what you tell me it should be done through Techstream?

Yeah, it's a TPMS sensor which the Italian MOT doesn't require either, but since the sensors are there, my ECU needs them to be functioning, otherwise it gives me an error. So unless I fix that, I'll be having the alert on my dashboard turned on forever, I fear.

Had to change a sensor in my tire. Found an (apparently) original one on eBay, but I still get an error in the dash. Wanted to understand why this is happening.

Hey all, I'm trying to find an iOS or Android app that has an exhaustive diagnostics for my 2006 GS 450h. Some have the GS model, but only go back to 2012. Anyone has experience with this? Thanks
