hi guys i need your help i have these codes on my 96 accord
code 17
D4 code 4
what are these guys and how ti fix?

 

Those both point to the VSS (vehicle speed sensor). Chances are your speedometer doesn't work...

If your speedometer works, then it's likely a wiring problem where the VSS signal gets to the speedometer cluster, but it doesn't get to the ECM & TCM. That's probably not likely & if it IS the case you'll want a wiring diagram from the shop manual.

 

thank you so much
