That sensor is an integrated part of distributor, not serviceable, According to my automotive database.

Thanks for the info its very important, the knock sensor is located top of the motor under the intake, i know iys a bad spot for it, make sure to get a delphi or dealer sensor, ive try them all and ended up doing the job twice so ive learned you get what you pay for, i would get the sensor from the dealer and the gaskets you can get from any parts store hope this helps, i've also included a diagram that show sensor to help you locate any others and it shows some what where the knock sensor is, good luck,

heres a diagram of sensor locations, not to clear.there are two knock sensors on this car there are also two engines that come in the q45, but the sensors are in the same place, they are located one below the leftside of the intake manifold and the other sensor is below the rightside of the intake manifold. hope this helps.

remove the intake manifold ,remove radiator ,remove radiator intake and outake housing, remove fan ,remove all belts: power steering, alternator and if you have a/c, remove harmonic balancer ,remove timing belt covers, remove timing belt remove intake housinng once you have remove all the above, your freaken engine will look naked, you can see the location of the knock sensor is locate in the engine valley

pore quality fuel will also set that code. dont get into too big of a rush to replace it . run a couple tanks of good gas first but here is a diagram that might help you out
thanks
