Hi. Does anyone has a ecm pinout of a 2006 Lexus rx400h? I am trying to figure out what wires are the knock sensor inputs on the ecm.

Thanks

This is no problem.

FYI, you don't need the full Hybrid ECM pinout for knock sensors which is good because the pinout spreads thru many different schematics, you only need the knock sensor info.
I'll post it up when I have time unless someone has it handy and wants to help.

BTW- what the issue with your knock sensors? Share the story if you like.

I recently got a check engine light, code p0333, knock sensor 2 circuit high input. I saw some videos how to cancel the defective sensor and feed both inputs pins from the good sensor. The guy that I watched was working on a 2007 rx330. the input pinout is not the same as my rx400h. t

This is for 2007 knock sensors.
Plz verify colors and match what you have before proceeding.

Knock Sensor Bank 1:
Connector: H33
Pins 28: white

Knock Sensor Bank 2:

Pins 20: green
Pin 21: red
