okay i have a 94 honda civic dx hatch when i was towing my car with no motor in it the mph gauges was working but when i swap my motor in./.... all the gauges on my cluster work fine... except the mph then i thought it was dead then i change it everythings work but not the mph gauge

have dis happen to any1 b4?

 

its happening to me right now my **** dances and i dont know why hpfully honda tech can tell both us whats wrong

 

make sure your connections are all plugged in tightly. every prong meeting the circuit from the connectors to the instrument panel in the back. you have to take out your cluster to make sure everything is tight and nothing is loose. this happened to me before and all i had to do is push my plugs in tightly and the speedometer worked fine. also one time my speedo and rpm and temp sensor did not work due to a fuse... lol just to throw that out there for you to check...

 

check your speed sensor. its probably a) not plugged in all the way or b) the female end has a crack in it and the male end is not being held in
