Sensors are installed all over a vehicle and accomplish many varied tasks. All sensors gather information that is fed into a unit control or the engine control computer to make all the parts work together harmoniously. Without sensors, things can be a lot simpler. But that can also mean that problems are not recognized as quickly. Sensors make it so that malfunction detection occurs before damage does. Though many find the multiple sensors in a vehicle annoying they are a blessing in disguise. Sensors are used for fluid level detection, air intake, air/fuel mixture, temperature, voltage and current amounts, and all kinds of measurement. They alert drivers to serious problems and minor problems. They can increase horsepower, efficiency, and create cleaner emissions. Though there are so many sensors in a vehicle it can be overwhelming to keep track of, they are an integral part of the modern vehicle and its highly efficient operations.
