The vehicle’s speed is often considered as the
most important quantity that must be measured in sports cars and race
cars. Speed defines the quality and performance of such cars, and
without them, they simply won’t qualify to be called so. The
measurement of vehicle speed, however, is not only important for race
cars and sports cars. This measurement is also important for passenger
vehicles, especially for the high quality ones like Dodge vehicles.
Speed measurement is important for Dodge vehicles because such measure is
needed by some vehicle systems for proper operation. Among those
systems that make use of speed signals for their proper operation are
the antilock braking system and the engine management system. And to
provide these systems with the data they need, Dodge vehicles are
equipped with Dodge speed sensors.
Dodge speed sensors are electronic devices that sends speed signals to
the various vehicle components that needs them. There are two general
types of speed sensors used in vehicles today. The first is the wheel
speed sensor, and as its name implies, it is used to measure the
rotational speed of a wheel on the vehicle. Wheel speed sensors
transmit the data they obtain to the antilock braking system (ABS)
management computer, which in turn processes this information so that
the system would know whether the wheels are locking or not.
The other type of vehicle speed sensor is the engine speed sensor.
Unlike the wheel speed sensor that is installed near one of the wheels,
the engine speed sensor is mounted on the engine’s crankshaft. The main
function of this speed sensor is to record the rate at which the
crankshaft is spinning. And instead of the ABS management computer, the
data obtained by this sensor is delivered to the engine management
computer, which in turn would modify engine functions and initiate
diagnostic routines based on the speed signal. Some Dodge vehicles
equipped with ABS would no longer make use of an engine speed sensor.
Instead, the engine management computer would just get the speed signal
from the wheel speed sensor through the ABS management computer.
