I have a 2002 nb miata ls with a jackson racing supercharger. I had tons of codes this past summer, one of which was for a knock sensor. I had two codes for problems with temp, and just got those fixed. I had cleared the codes for an inspection, CEL came back the next day. I didn't check to see which codes they were. Once I fixed the thermostat I went in and checked the codes before I cleared them. The only codes were for temp only. I have driven this car a total of six months or so, and I was filling it with 91 for a while. It has consistently had 93 for a few months. So is this mechanic in a bottle? Is shell telling the truth about their gasoline?
In reply to Keith Tanner :
I'm so sorry Keith, I do not remember it. I remember that the fix was a new knock sensor. As I said before, I cleared it to get an inspection sticker. The codes came back the next day. I was waiting to do all the jobs at once, but now I can't even find the old code.
If you can come up with it, I can look up the specifics of that code which will say how pervasive it is as well as likely failures to cause it. There is a code for a knock sensor circuit malfunction - but as the owner of a 1999-00 Miata, you need to pay close attention to the P030x random misfire codes, as that usually means coil failure which is followed closely by a destroyed catalytic converter.
Thanks! I'll try and find it. I know I wrote it down somewhere. This car had 100k put on it before I had it.
