Detecting a failure in this complex machine would be a tedious task. However, most of the vehicles today include computers (Electronic Control Unit (ECU)), which monitors several sensors, located throughout the engine, fuel and exhaust systems. When the computer system of the car detects a fault, two things are supposed to happen/monitored. First, a warning light on the dashboard is set, to inform the driver that a problem exists.
