Been doing lots of research and have not been able to figure out the problem.
It's a 2006 RSX Type S.
I replaced my starter a week ago, and in the process I accidentally yanked the wiring a little too hard while trying to unplug it from the starter and I ended up snapping the knock sensor. I went on Amazon and bought a replacement, not OEM, but a replacement with part number: 30530-PRB-A01
I drove it around and after about 40 miles or so, the check engine light came on. Pulled the codes and got the one for the knock sensor. I figured that didn't seem right.....so I cleared the codes. Ran it for another day, and it came right back. It has now started to run a little rich, so I've stopped driving it until I figure out what's going on.
Has anyone ever had this issue? Did I get a bad knock sensor, or are there differences between a k20a2 and K20Z1 knock sensor?
Or if anyone can point me to a known GOOD working sensor, that would be awesome.

I'm still trying to figure it out. I had no check engine until I replaced it.

all k20 knock sensors should be the same. you simply cannot trust an off-brand knock sensor. get a new sensor that is OEM and you will be problem free. if youre on kpro, just remove the knock sensor values.
No Kpro yet, hopefully in the future. I've never had an issue with aftermarket sensors with anything else. This is the first time something like this happens.

Just got an 04 base. had it 2 days and the CEL came on for the knock sensor. went to the local picknpull and got 2 knock sensors from 2 02' RSX and 1 from an 07' honda 4 cyl (same part #), paid $5.99 for it. put the one from the 07' in yesterday. drove around a bit. fingers crossed, it works, probably jinxed myself tho. been reading up on the issue, agree that the cheaper ones are hit and miss at best. good luck
Yeah.....I'm considering going to a junkyard to look for an OEM one. These cars aren't as common as they used to be.

I agree xDC5, ppl seem to hold onto these fun lil cars, not many for sale that ive seen. I used the O'really site to look up the knock sensor then used the drop down menu to find what years/models the same sensor is used for. turns out quite a few. there were only 2 RSX cars at the picknpull but maybe 18-20 various honda cars in all models and trim. its also a good place to practice takin stuff apart cuz you don't have to be nice lol. good luck
