I've had the VSS , speed sensor replaced so now the speedometer works all the time, but the CEL is still on. The code coming back is 0715. I took it to Honda and they service tech told me there was a bulletin in 1996 for the CEL and it was the EGR Valve and that it needing cleaning and cleaning the fuel rail. He says this will turn off the CEL. Has anybody done this and turned off the CEL? I saw another thread on this and will continue to search for it. But, I wanted to specify the code that I was getting. Thanks.

 

what is the bolt head size to remove the VSS??

 

Why not grab your metric socket set and see what one fits? I will tell you that it is metric for sure. I'm not going to go out into my garage just to find out for you......sorry!
