Re: what would cause a knock sensor to malfunction

I have no idea what you mean by 'running fine past the safety' - but, sensors go bad, which is why they sell replacements. Chalk it up to coincidence and go on (have it repaired or replace yourself).

That is for the knock sensor, bank 2. With transverse engine, the front bank on your vehicle should be bank two. You have more than one knock sensor, one for each bank.

It may but there are other sensors that will affect the idle performance.. Run fault codes first. Check the condition of the PCV valve and the EGR valve.
well this is a sensor problem. just cause you didnt get a fault code dome mean that the sensors are ok. Remove the abs Fuse from the fuse box under the hood. Drive the car and get a feel for the braking. Replace the fuse and drive again, you will notice one or more of the wheels dont hold as it fast or faster than the rest. Replace that sensor.
There are a few suspension parts that can cause knocking noises. Such as swar bar loose, strut mounts going bad. You should really have a shop do a complete suspension check.
If its an aftermaket installation, do yourself a favor and have it removed. I have seen them disable a vehicle where they won't start. Sound like the controller is malfunctioning.
