What will make a grinding noise that is related to the speedometer on a truck with a speed sensor system?

Begin by taking a closer look at the noise itself. Is it actually coming from the instrument cluster or is it just "under the dash" ? A short piece of old garden hose held to your ear will help you isolate the sound at its loudest point. Does the sound change (ie volume, pitch,etc.) with speed ? Is it always there or sometimes there ? Watch the needle as you drive and note if it holds steady, bounces or sticks at any point. Often, grinding noises associated with the speedometer are just the result of a worn drive cable. This runs from the back of the cluster through the firewall to the transmission. Over time, dirt and moisture can enter through worn seals and wick way up into the cable. The resulting corrosion can lead to erratic operation, cable breakage and grinding or ticking noises. Inside the speedometer is a friction drive that raises the needle based on how fast the cable is spinning. Without this, the needle would spin completely around or snap off the first time you accelerate. Bouncing or an abnormally low reading for your visual speed would indicate wear

It tells the computer how fast you're going. The data it produces is used by the speedometer and the cruise control system.

On the rear of the differential. This sensor feeds the speedometer and the rear ABS braking system. Basically a magnet simply held in by a bolt. Has an O ring to seal it.

There is a problem in the speed sensor system, the sensor isbad, the wiring is broken or has an issue. Repairing will fix both problems

Yes, but depending on the vehicle you may loose your speedometer. You will loose all funstion of your ABS system

93 Grand Cherokee does not come with a speedometer cable. It uses a VSS (Vehicle Speed Sensor) system. The VSS is located on the transfer case and has a electical cable that feeds the instrument cluster. 1992 was the last year that Jeep used a speedometer cable.

The cable that controls the speedometer needs to be replaced more than likely. That is what had to be done to a Dodge Stealth's speedometer to work properly. ==New Answer == Actually - there is no speedometer/odometer cable on a 1993 Honda. The system is all-electrical. So it has to be either a bad wiring harness/plug connector, OR a bad speedometer head (unlikely).

The speed sensor is actually the abs speed control sensor it controls ur abs and speedo it can affect the tranny shifting too there located on both sides of driver wheels hooked in the brake system. Passenger side wheel controls speedometer

At a minimum the speedometer and odometer will cease to function. But most newer cars rely on the speed sensor for a lot of other systems and will activate a 'limp home mode' if the speed sensor fails and could affect things like the ABS system and the transmission.

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).

the speed sensor should be located on the transfer case where the speedometer would go . there are several speed sensors on cars one at each wheel for the ABS system but a quick call to the dealer will probably help . on my 93 the speedometer sensor is located on the third member of the rear end.

The speedometer signal comes from the abs system, via the rear axle speed sensor. The rear axle speed sensor is mounted on the top center of the axle. The automatic transmission also has an output speed sensor, on the rear driver side, that is used for shift timing.

I want to say that it is located on the side of the transmission. The speedometer and odometer signal comes from the ABS system via the wheel speed sensors.

You need to have the system checked for trouble codes. You will most likely have a speed sensor code. If an auto it will be the output sensor on the front driver side of the trans. If a manual it will be the sensor on the right axle shaft housing.

You don't. There is no such thing as an odometer or a speedometer cable on that vehicle. The speedometer is electrically operated using a signal from the vehicle speed sensor. The odometer is driven by a little electric motor in the speedometer head assembly. If the speedo is working, but the odo isn't, you need a speedometer head assembly. If both are inop, you COULD need a speedo head, but there could also be a problem elsewhere in the system.

a speed sensor tells the vehicle computers how fast the vehicle is going, and also possibly operates the speedometer. If it is a wheel speed sensor it tells the anti-lock brake system how fast the individual wheel is turning and activates the anti-lock brakes in case of a skid.

At a minimum the speedometer and odometer will cease to function. But most newer cars rely on the speed sensor for a lot of other systems and will activate a 'limp home mode' if the speed sensor fails and could affect things like the ABS system and the transmission.

A 1996 Dodge Ram does not have a speedometer cable. The system is all electric.
