Function of the sensors and sensors for bakkies working together with the main computer

Computers bakkies can carry only what they are programmed to in advance. On the computer of a bakkie, is an engine management system called Powertrain Control Module or PCM. Data for these systems is collected from various sensors.

Sensors appear and act as the eyes and ears of the internal combustion engine and help its proper handling and operation in various conditions, while driving. Therefore, Powertrain Control Module (PCM) may not work properly if the sensors are defective or missing.

For example, the control system of the engine will not operate if the bakkie's computer (PCM) did not get a good signal from the coolant sensor or oxygen sensor. Nor will fuel mix properly if it does not get a good signal from the position sensor throttle, MAP sensor or airflow sensor.

The engine can not be started if the computer does not receive a PCM signal from the position sensor crankshaft. Sensors ensure the supply of fuel, emission control, transmission gears and cruise control management.

Other sensors monitor the reduction in engine torque if the vehicle has antilock brakes and traction control, reporting the output of the alternator. In many bakkies, commercial vehicles and cars, PCM computers control throttle with the signal from the sensor. Sensors for bakkies must be absolutely  reliable to operate the whole system smoothly.
