The car listed above has automatic transmission and 68,000 miles.

I have been driving my car around town and my speedometer will all of a sudden go to zero and I'm still going at what I think is about 30mph and if i hit a bump in the road it will go back to 30MPH. Please Help!

your vehicle's speedometer is controlled by the vehicle speed sensor (VSS). If the speedo is operating inaccurately then the VSS is most likely failing. also check for loose connections at the back of the instrument cluster.

Hello,

Inoperative speedometer can be due to a faulty vehicle speed sensor (VSS).
The VSS is located on the transaxle.

I have attached the diagrams below for your reference.

Please let me know if you have any questions.
Thank you.
