yeah i meant knock sensor, my bad, but yeah, what is it and how do i get a new one.

its a pizzo (sp?) crystal that detects pinging noises in the chambers. its located on the backside of you're head under the intake manifold. get a new one from acura or honda, just ask for a knock sensor. best advice i can give is get one from a junkyard car because it'll be cheaper.

knock sensor - around $120 from autozone, or around $180 from honda/acura. If you can find used, good luck. I spent a month looking for a used one to save money.. no luck. I looked through all of tennesee and southern Ontario (when I was home for thanksgiving) and couldnt find one. Best bet, buy new. not that expensive.

The knock sensor is located underneath the intake manifold (92-93 GSR's) might be different for yours. 5 minute change at a shop if they lift the car.

if the knock trips code, vtec wont activate.
