1) I bought a Bosch one online from a reputable parts shop (not Subaru) and when I installed it the CEL went away (Code was P0325)Hey guys - two really quick questions about knock sensors, as this is quickly looking like it might be the part truly been behind my CEL woes for two years.
1) I've seen them for as low as $30 shipped on eBay. Is that something I should be weary of?
2) I've seen it written in some places that an audible "knocking" is something that may be indicative of a bad KS. For a long time, when I've started up my car, I've heard kind of a rapid knocking sound that persists for a brief period, but generally goes away shortly after I start driving. Not very descriptive, I know, but is there any chance that this might be that knocking that they're referring to?
Thanks so much!
