Hey… I have a question regarding the Lexus knock sensor in a 2001 Lexus ES300 V6 3.0L. Is there a difference between knock sensor bank 1 and 2? Can I use the knock sensor from bank 1 on bank 2?
Yes. You can use the knock sensor from bank 1 on bank 2. The two sensors have the same part number: KS159 and run about $140 each. There is no difference at all since the part numbers are the same. So if there is a benefit for you then go ahead and swap away.
Knock Sensor Location
Both knock sensors are located underneath each engine cylinder head assembly. They are mounted in the engine block. I recommend using a SST Socket number 09816-30010 hence making it easier to remove.
