I was just driving on my Civic. And when I´m driving the speedometer goes crazy. I´m maybe driving on 50 mp/h and then he goes crazy, goes up too 120mp/h.
Does somebody knows what is wrong. This is Civic EX '95
I unplugged the sensor last night and plugged it back. And then it didn´t work. So I thougt maybe it would work if I would put battery terminal grease. And it worked
