Hey 1997 civic dx here 5 speed manual trans engine light on. Codes say speed sensor. So I bought speed sensor the one onthe trans on e-bay and no help spped-o bounces around and engine light on. Also lights pulse with a/c on. Any help on this on would be great thanks

 

if you posted in the correct forum, you'd get more help. most of us don't even have speed sensors in this forum.


check the wiring and the connector. also, check the ground on the thermostat housing and make sure it isn't loose.
