Speedometer/mile counter problems Sign In
So um, the one day I was going to school and I looked down at the speedometer and it said I was going 50 and i was like okay. well then i looked back a few minutes later and it was at about 25. Well on the way home from school the speedometer was dead, as was the mile counter and the overall mileage. I have absolutely no idea what to do about this. I don't know a whole lot of anything about cars and I was wondering if someone could help me. Thanks.

Also in case it helps, my car is a 1999 Mercury Tracer. thanks

The vehicle speed sensor and its circuit should be checked. This runs the speedo and gives the PCM vehicle speed.

Re: Speedometer/mile counter problems Sign In
The VSS circuit should be checked. The PCM needs to see vehicle speed for the cruise control to work. The VSS operates the speedometer also. The VSS may kick the MIL to alert the driver of a problem. The speedo and cruise rely solely on a vehicle speed signal or these systems will fail.
