The engine control module basically controls many different elements whose work is necessary for the proper operation of our engine. The engine computer basically monitors many different devices and systems in our car.
It monitors many sensors located at various points in our car, and regulates the work of the entire system. One of its roles is to monitor the mixture burned in the engine compartment, the idea is to properly select the amount of air to the amount of fuel. Thanks to the throttle, the air reaches the chamber depending on the needs, similarly the electronic fuel injection adjusts to the power expected by the driver after pressing the gas. Earlier, when the foot touched the accelerator pedal, it was connected to the cable leading directly to the engine, so that the engine could decide how much fuel to inject, based on the force with which the pedal was pressed, it was a mechanical way. Currently, an electronic sensor on or near the gas pedal sends a signal via an electric wire to the engine control system, which evaluates the throttle condition, and then sends a signal to the engine to adjust the fuel dose.
Another task of the engine controller is to calibrate the throttle position at idle, i.e. what amount of mixture should be delivered so that the engine can work constantly. When the system detects irregularities,
it can, for example, automatically reduce engine power, and thus speed, then informs the driver of the irregularity. The power is maintained at a level that will allow, for example, access to the site. Sometimes, there may also be a situation when the computer prevents the car from ignition if it detects a very dangerous situation such as a drop in brake fluid pressure. The engine computer also ensures that the car meets emission standards by monitoring and adjusting the fuel mixture to make sure that the engine does not run on a too rich mixture and does not emit pollution exceeding the set parameters. The computer’s role is also to supervise safety systems such as ABS and ESP, airbags and belts. It also controls cruise control and alarm, what’s more, the engine control module undergoes a recalibration test every time you turn on the car to make sure the signals are correct. However, our computer engine may be damaged, then we should consider whether to buy a new one or have it repaired. It is a device that manages car systems just like the motherboard manages computer components.
Repair will therefore require specialist knowledge of electronics. The lack of proper operation can also be caused by other factors. It can simply be a failure of the sensor or the cable through which the signal flows to the control unit. Sometimes, however, you will just need to buy a new device, you won’t always have to choose a new model. You can buy a motor driver used from the same car model and program it for our car, many models can be found at: https://www.worldecu.com/en/ecu-engine-control-unit.
