Yeah, I've heard about sealing around them with RTV after install. Have you given it some time to dry out and see if the code goes away?

they are under the intake and sit in little wells that pool water. if the water is allowed to sit in there the knock sensors rust real bad. it is best to make sure you run the car immediately after washing down the motor to make sure the water evaporates from the engine heat.

the sensor (there are 2) has a wiring harness with a rubber boot that is supposed to seal the hole where the sensor sits. silicone all around the boot.
