Hey guys, i need some help. A few weeks ago my engine light went on. When i checked the codes, it was for the knock sensor and the speed sensor. I got it checked out by a non-dealer and they said nothing was wrong with the parts, and that i should take it to the dealer if the light goes on again. Well couple days ago, the light goes on again, except that this time its for the automatic transmission communications line, the knock sensor and the speed sensor. Any ideas? The dealer said it would be like $80 just to check it out. So i'd appreciate and help. Thanks

Bill, you should make that a Sticky.

 

I already saw the descriptions on the diag trouble codes and they did kinda help, thanks. But since I'm not a mechanic and i'm not really electronically inclined I don't think i can really check all that stuff by myself. I was hoping/thinking there might be some common electrical problem associated with this.
