Hey whats up, I drive a 1999 Honda Civic (92K miles). Recently, the speedometer started to malfunction. This is the best way to describe it: the car always starts at 20 mph, and will stay this way. Upon braking, the speedometer will fluctuate from 15-25 mph, and come to 20 mph upon stopping. Sometimes, the speedometer will work if I push the "reset mileage" button twice or if I accelerate on the highway (although not always). Long drives are often a mixture of periods of working speedometer to malfunctioning speedometer (seems like 50-50), When the speedometer is like this, the odometer does not track miles. However, when the speedometer is fixed, the odometer acts normally.My question is: whats wrong? how much will this cost to fix? and since the speedometer seems to work fine sometimes, can this be fixed at home?
