2007fusion100kontheclock Report post Posted April 21, 2010 I have a 2007 Ford Fusion SE 4cyl with 105K miles. Runs great. However, just yesterday, the speedo started going crazy, even though I wasn't moving. Then it would rest at zero. As I drove, it would go crazy again every time the car would switch gears. Has anyone ever seen this? I assume its the speed sensor, but not sure. Any help out there?? Thanks! :sos: Quote Share this post Link to post Share on other sites
