So, I started getting one of those "Emissions system problem!" and "Electronic emergency brake problem!" warnings a couple of weeks ago. My OBD scanner says it is a knock sensor code. An OEM knock sensor costs about $150 and a third-party knock sensor costs about $50. Does anybody have any experience with using a non-OEM knock sensor, good or bad?

 

Will you be DIY'ing the replacement or paying a mechanic?

 

Planning to pay someone for this one. I heard it's not an easy job.

 

Thanks for the response.
That is why I asked, though there appears to be two, one for each bank. If you want to receive the same or longer life of about 7 years, you'll want to invest in OEM knock sensor(s); otherwise, settling for a cheap foreign knock-off, for your expensive / reliable RLX, might have you paying to repeat the repair sooner then you'd like, IMHO of course.
#12 below is the knock sensor and gives you an idea of where it lives.



Good Luck!

 

Thanks, sounds like it might make sense to go OEM on this one.
