The ECM is essentially the brain of the engine, constantly monitoring and adjusting various parameters to ensure the engine runs smoothly and efficiently.

The ECM is responsible for controlling the fuel injection system, ignition timing, emissions control system, and various other engine functions. It receives input from various sensors located throughout the engine and adjusts the engine's operation accordingly.

One of the key functions of the ECM is to adjust the fuel injection system to maintain the optimal air-fuel ratio for combustion. This not only ensures optimal performance but also helps reduce emissions and improve fuel efficiency.

The ECM also controls the ignition timing, ensuring that the spark plugs fire at the right time to maximize power output and fuel efficiency. By constantly monitoring engine speed, load, and other parameters, the ECM can make precise adjustments to the ignition timing to optimize performance.

In addition to controlling fuel injection and ignition timing, the ECM also monitors various other engine parameters such as coolant temperature, air intake temperature, and engine speed. By constantly monitoring these parameters, the ECM can detect potential issues and alert the driver through warning lights on the dashboard.

Overall, the engine control module in a car like the Toyota Camry plays a crucial role in ensuring the engine operates at peak performance while also maximizing fuel efficiency and minimizing emissions. It is a sophisticated piece of technology that helps make modern cars more reliable and efficient.
