The speedometer and speedometer cable tells the driver how fast the vehicle is going. What's called a Hall-Effect sensor is used. It uses the principle of magnetic inductance. When a magnetic flux passes through coils of wire, voltage is generated. To use this effect, a magnet is placed in the cars differential. The sensor then can tell when the magnet comes around by a spike in voltage. Since there is a constant amount the car moves with each differential rotation, and with the time between voltage spikes, you can easily divide to get the speed. This is why changing your cars tires will affect your speedometer. Your car assumes that car moves a certain amount with each differential rotation. If you have larger tires on, then each differential rotation (and axle rotation) your car moves further, and you'll move faster than indicated.speedometerspeedometer.A speedometer or Machmeter.The instrument that is used to measure speed is called a Speedometer. This may sound obvious, but it is the correct name for the instrument. All motor vehicles by law will have this.The speed of what? The one that measures the speed of a vehicle is called a speedometer.The device used to measure the speed of the car is known as speedometer.Transmission output sensor is usually used as the input sensor for the speedometer, also the braking system uses the wheel speed sensor to determine if a wheel is slowing faster(locking up).
oxygen sensor
analog sensor
A sensor that measures flow and pressure of the fluid in a hydraulic system.
A limit switch turns on or off when the object being sensed reaches a specific location.A proximity sensor returns an analog signal indicating how far the object is from the sensor.
You have a bad Vss Sensor.............. The vehicle speed sensor.
It has an electric speedo and has a speed sensor.
it is a defective speed sensor.
One indication of a bad sensor is when your speedometer bounces around, shakey, or jumpy.
Yes. The rear axle sensor feeds the ABS computer which feeds the cluster and the speedometer.
yes it has a speed sensor near the end of the tailshaft of the trans.
doesn't use a cable, it uses an electric sensor
It is an electric speedo so it can be the speed sensor or in the speedo itself.
speed sensor is out or is going out. your speedometer is out too right?
where is speedometer sensor on 2004 avalanche
The speedometer is electric, there is no cable. There is a speed sensor on the transmission that sends a signal to the PCM, which in turn sends a signal to the instrument cluster to display speed.
