The fuel level sensor sends a varying signal to the fuel gauge or electronic gadget that triggers the fuel gauge. The components of the sensor, such as float, rod and resistor, work together to give a reading on the level of fuel.

The speed sensor of a vehicle is usually located on either the transmission case or the rear differential assembly of production vehicles. Check your vehicle’s service manual or spare parts catalogue before looking for its speed sensor because vehicle speed sensors come in several different designs

A temperature sensor measures the hotness or coolness of an object. The sensor’s working base is the voltage that’s read across the diode. The temperature rises whenever the voltage increases. The sensor records any voltage drop between the transistor base and emitter. When the difference in voltage

While manufacturers use different types of coolant-level sensors, the simplest is a float that activates a switch. If the coolant drops below the designated level, the switch opens, sending a signal to the indicator light. Manufacturers install these switches either in the coolant recovery tank or i

Oxygen sensors are electronic devices installed in motor vehicles manufactured after 1980 to measure the ratio of oxygen in a car or truck's gasoline. When gasoline contains too little or too much oxygen, it is harmful to motor vehicles as well as the environment. In the case of too little oxygen, t

Parking sensors use ultrasonic or radio waves that reflect off of objects behind the vehicle to let the driver know how close they are to hitting the object by emitting a beep as a warning. They allow the driver to be more confident while parking and driving in reverse.
