ECU pin diagram for a 2001 lexus gs430?
Iv been looking everywhere and I can't find it. I found it for a gs300/gs400 but none for the 430, i need to get to work, my #1 knock sensor is bad and I need to do the hack just until I get paid cause its 970$ to do the sensors and harness. And I want to do the starter at the same time. I guess there is no shortcut for the knock sensor replacement and I don't trust myself to take the whole intake manifold off. Please help, I need to know witch ones are the knock sensor wires

For what its worth the Knock Sensor replacement is not as bad as it seems. I have large hands and was still able to replace them without taking the intake completely out of the car. I just unbolted it and lifted it up enough to get to the sensor. Beware of the sharp edges of the intake though.

Here is the diagram you were looking for.

I just saw this one, this guy said he used it for his gs430 to do his srt intake install.
. Knocking signal is the knock sensor right?

I gave you a wiring diagram. That other picture you found is a pin-out diagram of the ECM with no colors indicated. They are not the same thing and therefore can both be correct. Update - I think that other diagram is wrong.
Sensor 1 is gray at the sensor and white at the ECM.
Sensor 2 is black at the sensor and the ECM.
I'll try to check my source for a better pinout diagram in the morning.

Ok so I think that other diagram is incorrect. His "Signal 1" is sensor #2 so you need to use his "Signal 2" to get to Sensor #1.
DTC P0325 is for knock sensor No. 1, which is located on left side of cylinder block. Per the Lexus wiring diagram for your car Sensor No 1 has a white wire at the ECM and is plugged into connector E3's #2 position, it is labeled KKNR in the wiring diagrams.
As always use my info at your own risk.
