Throttle body models of Camry3.0 or ES330 fits in ES300 ??
My 2002 lexus ES300 recently shows fault code p1128 and enginge shuts down immediately after ignition.
Local mechanic found that the throttle body is stuck and need to be replaced.
I found that the similar models with 1mz-fe,3mz-fe engine like 05' Camry 3.0 & ES330 have different throttle body part numbers：
22030-20020(camry3.0)
22030-20030(es300)
22030-20060(es330)
I'm wondering if all these different-part-number throttle bodies are actually the same? Cuz all these car models look exactly the same under the hood(their engines, tubes & hoses configurations...etc.) And maybe their throttle bodies can all be fit in my ES300??
I asked the mechanic, the parts dealer, and search some local forum articles in my country. None of them are so sure about this....
Sorry for my bad english. I'm really not a native speaker.

Hello,
It appears that 22030-20020 and 22030-20030 are functionally identical, if anything, 20030 may end up being an improved version of the old Throttle Body. With that, 22030-20060 off of 3MZ engine is different, it doesn't have a Throttle Position Sensor on it, so it won't be compatible.
It is strange however that the Throttle Body would get jammed stuck, haven't heard of it being an issue with those cars, cold just be my ignorance. It is hard to say anything definitive without seeing the car, a video of the Throttle Body that you have currently may be helpful.
Usually when the Throttle is jammed, the car will either not start at all, or will stay running at some random RPM. When the car starts fine but dies immediately, it indicates that one of the sensors may be malfunctioning, as until the engine starts running by itself, without the starter engaged, the ECU doesn't reference any sensors other than a certain few, P1128 code is one of the contributors for this theory. One way to test it would be to unplug MAF and A/F sensors, then try starting the car again, it will run rough, but if one of the sensors is the cause, it will at least stay running.
Hope this helps and best of luck!
