Hello,

I am having my knock sensors replaced this Tuesday. My mechanic asked me to buy the sensors, intake manifold gasket and also the pigtail harness. I am having trouble finding a pigtail harness for this car. Even went to a Lexus dealer. It doesn't show one in the part schematics they have on the computer.

Is there a pigtail harness for the knock sensors or are the connections on this engine part of the main wire harness? Any information would be appreciated. I'm at a loss.

Thanks.

 

Found it through some research. Hope this helps anyone with the same question and problem.

 

I'm curious: what did the dealership quote you for the replacement of your knock sensor and harness?

My mom's 2001 LS also has a bad sensor (apparently, mice chewed the wires), and the local Toyota dealership is quote *8* hours of labor (at $140/hr)!!

Many thanks in advance,
Marc Jacobi

 

I'm in the same boat... What part numbers do you have for the 3 gaskets needed ?

 

Just wondering, as I have someone doing my car as well, the 82122 part (Knock sensor harness) points to a ton of different engine parts for different models, It's hard to know what is what. Is it a 82122-30830 for a 2001 LS430? Is there a way I can confirm this, I would like to buy the part online to save a little but, I want to make sure I am getting the exact part I need.
