Question: 1999 Honda Civic EX mileage: 94,000. Speedometer problem. Car was wrecked on the front driver's side. Engine and transmission removed to replace part of framing. When removed, coolant got into the Speed sensor and Electrical plug connected to it. When car was finished, everything worked fine. Then about a week later, the speedometer dropped to zero for long periods of time and finally quit. The speed sensor was replaced and everything worked fine for six months and then all of sudden it started jumping around. It will drop to zero and will jump to 100 mph. Sometimes the Needle will jump as soon as the car is started. I have since replaced the sensor as well as spliced in a new plug elimination those two areas. What do you think the problem is? What is the best way to trouble shoot this without pay Honda a fortune or just replacing everything?
Answer: Because you replaced the speed sensor and are still experiencing the problem, we suspect that you have a faulty speedometer head.
