Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hi, it sounds like you have a VSS vehicle speed sensor problem,the signal is dropping out,causing the speedometer to cut out and the radio volume to diminish,and the slight engineproblem . To check this would require a test with a scan tool, seeing if any codes are stored, and to test if the signal is being lost from the sensor when the problem occurs. I will send you pictures showing the location of the sensor and the speed control module ,I would look to see if the connections are intact, if so I thenwould replace the sensor,unless you have the equipment to do the testing. I hope this will help you with the problem,thanks for using Just Answer,Jerry.
