When Repairs are Completed Car Computers Times have changed and so have cars.
Computers are smaller, more powerful and more complex every year.
This allows auto manufacturers to use computing power to optimize engine performance and monitoring. One or more microprocessors that receive input from these sensors to control emissions and fuel economy. The microprocessor in turn controls actuators and relays that set idle speed, shift the transmission, control the fuel pump and fuel injectors and even the engine cooling fans and air conditioning system. Electronics now control more than 86 percent of all systems in your vehicle. Electronics make cars more enjoyable and reliable, but also more complex.
