Honda speedometer

my speedometer in my 93 civic no longer works as it should. it either doesnt work at all or it jumps all over the dial… any suggestions?. thanks

The 1993 Honda Civic speedometer is electronic. It gets a signal from the VSS (Vehicle Speed Sensor) on the transmission. The wiring from the VSS to the speedometer display could have a poor connection, or a braided wire, or, the VSS could be bad. Use a digital voltmeter to check it out.
