My speedometer stopped working a month ago. They said they ran it through the diagnostics and that it stopped at the speed sensor. They said they ordered the part. Today I took the car in and they told me they replaced the speedometer sensor and the speedometer still does not work. And now they say they must order the speedometer for a Honda Civic EX 99. My question is how do i know the original sensor was bad in the first place. The guy told me that once the diagnostics hits the problem(the sensor) it wont go any further until that part is fixed.
Was it the right thing to do to replace the sensor...the speedometer would stay at 20 the majority of time before I got it fixed and now it is still doing the same thing. And I paid 120 to replace it. After doing some research I found that it may be the speedometer portion of the cluster assembly. Any advice or help would be greatly appreciated. Thanks.

 

welcome to the forum. Yes if you have a diagnostic machine, it will normally go to the trans speed sensor before the speedometer. They should have advised you that the odometer also could be at fault.
