A few questions regarding my 2014 RDX knock sensor. Any insight would help.
100k on the odometer. Scanned it and only one code for knock sensor came up. No symptoms other than dash check engine.

1. How many knock sensors are on this suv?
2. Will using higher octane clear it?
3. The code appeared 20 miles ago. Can I drive it for a couple hundred miles without hurting anything?
4. I'm fairly confident I can tackle the job. How easy is it the replace.
5. Where is it/they located?
Thanks for any input.

 

The video linked below is essentially what you'd have to do. Have you been filling up with premium gas (91+ Octane)?
