Hey everyone. I posted around a year ago regarding a p0325 code for my knock sensor, I had suddenly received the code out of nowhere and eventually got it fixed with a new sensor. Fast forward to now, didn't have any issues until the other day when I got another check engine light, and what do you know, it's the p0325 knock sensor again. Surely there must be something else going wrong apart from this sensor, this time I did notice however that the check engine light came on as I was accelerating a bit hard and hit 5k~ RPMS, if that's any clue. The current sensor in my '03 CL9 (145km's) is genuine and was brand new.

I'm going to take it back and get it fixed again obviously but I'm curious if anybody would have any idea why this happened again so soon. I just really don't want to keep forking out money for this thing, thanks for the help!
