[quote=”mcconnell.202″ post=36865]Hi Eric, long time viewer, first time poster here.
I just thought that I would share my experience with a similar issue on my ’95 Honda Civic EX automatic. My speedometer was always either bouncing around, working fine, or not working at all at random for a long time. I had cleaned the sensor plug hoping it was that and I wouldn’t have to shell out money for a new sensor. After the issue persisting, I discovered that if I pushed or tapped the trip reset button while moving, the behavior would always change (mostly it would start working fine again for a few miles) but that obviously wasn’t a permanent fix so I tore into the dash. To my suprise, I did not find any loose wires or cracked solders. However, behind the speedometer there are pins (8 I believe) that connect the speedometer to the circuit board. I believe that the pins had just become too worn to maintain proper connection. I tried dielectric grease, bending them slightly both of which worked but only for a few months at a time. I finally ended up going to pull-a-part and purchasing a new (to me) speedometer for $15 and haven’t had any trouble since. I thought that this information may become useful to someone wants to eliminate one more possibility before they shell out close to $100 on a sensor that they may or may not need.

Yea this is the other possibility. 2 things though. The first is that in your situation you won’t get a P0501 because the speed sensor IS sending a good signal. The second test in that situation which I wish I would have mentioned in the video now was to try and set the cruise control. If the cruise control sets then the sensor is NOT the problem, if it doesn’t’ set then the speed sensor is the problem or it’s wiring. There are some known issues with those clusters similar to what you describe but not as common as bad speed sensors themselves in my experience.
