How fast the vehicle is traveling.
road speed
Older cars have a cable, which is turned by a gear at the rear of the transmission, and this operates a mechanical speedometer. Modern cars have an electronic sensor in the gearbox which is linked by wire to an electronic speedometer.
A speedometer is a tool used to record a cars speed.
There is no speedometer cable to change. Subaru, like all modern cars, has an electronic speedometer. --Ken
This is not a question. Tell us what you want to know.
To some extent, it can be used as a speedometer. However, it is nowhere near as accurate as your cars speedometer. There will also be a greater delay in the changes in speed than with a normal speedometer.
There is no connection.
NOT! It is illegal to tamper with an odometer.
A cars speedometer measures speed. A speedometer is a gauge that displays the speed of a vehicle so the driver will know how fast the vehicle is moving.
The speed of most cars today is limited by the computer, no matter what the speedometer says. My car's speedometer lists 140, but it actuality 120 is the top speed as the limiter kicks in and controls the speed by way of a fuel shut off.
Drive slower, and the speedometer decreases. If you are asking how to (illegally) decrease the odometer's kilometer reading, then shame on you.
Speedometer calibration differs depending on the vehicle and age. Some cars are calibrated by a technician with a computer program. Others require a gear change to drive the speedometer at a different ratio.
