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.

Info
Thanks debon! I ended up cutting the white wire and ended up with code p0330. So the white wire was my circuit 2, the working circuit. and the black wire was was my faulty circuit so that's the one I spliced into the white wire. Thanks! I hope this will help other gs430's owners do the sensor Hack in the future if needed.

What is specifically your trying to do? And what are the specifics on your vehicle? Likely a current member will be able to help you out with a better understanding of what you are trying to do?
