I couldn't figure out how to add my car to my garage, but I have a 1991 Honda accord Ex 2.2 L. Since i received the car the speedometer jumped around a lot. I touched the wires on the vss to try and locate it and after that it completely died on, reading at 0 no matter what. I got my hands on 4 different (scrap yard) sensors and exchanged it. It worked fine the first day then it started reading at zero until i had driven for about ten minutes. After that it would work fine so i decided to switch it again but now the spedo stays at zero even after driving for an hour.

I checked to see if the tiny rod that goes into the sensor spinned without the sensor on and it did. I also tested the black and yellow cables and they both seem to be ground, this is what im guessing the problem is. I dont know what else to check any help would be appreciated. I hope i make sense im very sleepy and i dont think im writing cohesive thoughts.

 

A bad connector? You "touched" the wires and things went bad. Go back to the bone yard and get the harness that goes to the VSS.....splice it in - be sure you have a good connection. See what you have from there.

 

So you were right, I came home the day after this post and the car had been taken to the mechanic(much to my wallets distress). The mechanic ignored everything i had already done and put a new vss, different cluster and when all that didn't work he checked the cables that connect to the vss and found the problem. Had i had that car one more day i would be 100 dollars less poor. Anyways thanks for your help sorry for the late reply.

 

My pleasure......glad you are back in working order, less the cost.

Thank you for coming back with the answer, it helps the next person that does a search......
