What does the speed sensor on a Ford do?
by Thomas West. The vehicle speed sensor (VSS) on your Ford vehicle is an electronic device that measures your vehicle’s speed. This information is sent to the electronic computer module (ECM), where it is shared with other vehicle systems that depend on this data.
Can a faulty speed sensor cause a problem?
The sensor does this by recording how fast the crankshaft of your vehicle is spinning. A faulty speed sensor can cause all sorts of strange problems in your car. A faulty vehicle speed sensor can cause an array of problems.
What is the name of the transmission speed sensor?
There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle’s powertrain control module. The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’s input shaft. The other sensor is the output shaft speed (OSS) sensor.
How is the frequency of a speed sensor determined?
A number of teeth or slots are arranged radially which, with the speed of rotation of the road wheel, determine the frequency of the signal transmitted to the electronic-control unit. As the wheel and excitor revolve, the teeth and gaps or ribs and slots of the excitor pass through the magnetic field of the sensor.

Where is the speed sensor on a Harley?
Behind the transmission top cover and near the starter. Had the same problem on my 2000 ultra. Had to change to what my mechanic called a maxi fuse. The one under the seat left side that has the starter wires to it. Have not had the issue of dying at highway speed since. Ran me all of 15 dollars. Good choice for me.
Where is the speed sensor located on a Dyna Wide Glide?
I have a 2007 dyna wide glide, where is the speed sensor located? I do not have a service manual. Behind the transmission top cover and near the starter. Had the same problem on my 2000 ultra. Had to change to what my mechanic called a maxi fuse. The one under the seat left side that has the starter wires to it.
What should I do if my speed sensor is bad?
Your speed sensor reports to your module, information, that is used for signal cancellation based on distance/speed. Check your speedo head for stored diagnostic trouble codes. If your problem is not a bad speed sensor, it may be a bad TSSM (turn signal security module ).
