The engine control module (ECM), also known as the engine control unit (ECU), is a crucial component in any modern vehicle.
In this case, I will be discussing the ECM in a 2021 Toyota Camry.
The ECM in the Toyota Camry is responsible for monitoring and controlling various aspects of the engine's operation. It gathers data from sensors located throughout the vehicle and uses this information to adjust fuel delivery, ignition timing, and other engine functions to ensure optimal performance and efficiency.
One of the key functions of the ECM is to regulate the air-fuel mixture entering the engine. This is done by constantly analyzing data from the oxygen sensors to determine the ideal ratio for combustion. The ECM then adjusts the fuel injectors to deliver the correct amount of fuel, resulting in efficient fuel consumption and reduced emissions.
The ECM also controls the ignition timing, ensuring that the...
