The engine control module (ECM) in a Mazda CX-5 is a critical component of the vehicle’s operation and performance.
The ECM is responsible for controlling the engine's functions and ensuring that it is running at optimal levels.
The ECM constantly monitors various sensors located throughout the engine and vehicle, such as the oxygen sensor, throttle position sensor, and engine temperature sensor. These sensors provide data to the ECM, which then adjusts various parameters to ensure the engine runs smoothly and efficiently.
One of the key functions of the ECM is to control the air-fuel mixture in the engine. By constantly monitoring sensor data, the ECM can adjust the fuel injection and ignition timing to ensure the engine is running at its most efficient level. This not only improves fuel economy but also reduces harmful emissions that can be emitted from the vehicle.
The ECM also controls othe...
