Speedometer intermitent Honda Civic?
If it is a cable-type speedo it may be loose. Follow it from the firewall to the transaxle and tighten if possible. Other wise it may be broken. If it is electronic locate the sensor on the transaxle and check for tightness and clean if necessary. May need replaced altogether though. The ECU may also be at fault.
What could be the problem on a 1993 Honda Civic VX If the speedometer odometer intermittently works and you have replaced the speed sensor on the transmission?
The cable that controls the speedometer needs to be replaced more than likely. That is what had to be done to a Dodge Stealth's speedometer to work properly. ==New Answer == Actually - there is no speedometer/odometer cable on a 1993 Honda. The system is all-electrical. So it has to be either a bad wiring harness/plug connector, OR a bad speedometer head (unlikely).
