Honda Car Forum

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?

My first thought would be the drive in the gearbox is at fault, I have seen very few speedo faults but quite a few gearbox faults that have similar symptoms.Get it checked out at a garage, the drive can be replaced but may be expensive, might be easier to replace the gearbox with one from a breakers.

woah woah. dont go and have your tranny torn apart. fix the cheaper things first. get your speedo sensor replaced. it sits right on your tranny on the outside. if that fixes it you saved a shit load of money for labor. if that doesnt work get it diagnosed and then if they need to tear it apart for the gearing then go ahead. but really. make sure it isnt the simple easy cheap fix first!

my nissan did the same thing i took it to a mechanic and all he did was spray some sort of lube on it he didn't charge me anything for doing it.worked fine after that

all those can be a reason but my civic did the same thing cuz i spilt my drank while drivein and i changed my cluster and it worked fine the miles may be diffrent but that wont matter

if you don't have a check engine light on its probably gonna be a bad speedometer head,there is no gear or cable on these cars that go bad.you need to check the wire harness that runs along the back/underside of intake manifold sometimes the wires will rub through on intake bracket and cause weird problems like this.there is only three things that could cause this speedo issue 1 broken wires to speed sensor(that usually makes chk.light come on)2 bad speed sensor(that also makes chk.light come on)3 bad speedometer. im gonna guess its the speedometer itself. honda tech 11yrs.

Could be the speed sensor in your Civic is at fault. Check it out asap.
