Front wheel drive automatic. The speedometer registers speeds inaccurately. until you hit 55, the speedo is 5-8 slower than actual speed, past 55 it registers higher than its actually going. And just today for no clear reason, the speedometer randomly stopped working for a moment but ONLY the speedometer. The rest of the cluster was working fine, no CEL, and all lights are working on the cluster itself. I checked the fuses, nothing is dead, missing or loose. Everything else on the car that is electrical seems to be working fine, so I figured I would just have to take it to a mechanic monday, and then it randomly started working. No indication what the issue might have been.

Was told it could be the speed sensor, and a google search or two didnt turn up a relevant topic here so I made my account to ask.

Any help or advice would be greatly appreciated.

 

It's either the VSS or the speedometer itself is going bad.

 

For me it was always the speedometer though i always try the vss first.

 

Mines the opposite, it's accurate until 45-50 mph, anything higher and my speedo reads 5 or 6mph high. I found this out using a gps app and the clocks they use at construction sites. But it never bothers me enough to look into it.

 

Diitto, i just drive by my tach when the car acts up. When i put my good used engine in , i will use the speedo from that parts car that has way lower miles rather than buying a speedo.
