This small but powerful computer is responsible for monitoring and controlling all of the engine's functions, from fuel injection to ignition timing.

The ECM constantly receives information from various sensors located throughout the engine and adjusts the engine's performance accordingly. For example, if the engine is running too hot, the ECM may reduce fuel flow to cool it down. Or if the car is accelerating, the ECM will increase fuel flow to provide the necessary power.

In addition to monitoring and adjusting engine performance, the ECM also stores crucial data about the engine's operation. This information can be accessed by a mechanic using a diagnostic tool to troubleshoot any issues that may arise with the engine.

The ECM in a Toyota Camry is designed to be reliable and durable, but like any electronic component, it can fail over time. Common symptoms of a faulty ECM include issues with starting the engine, poor fuel efficiency, and a lack of power. If any of these issues occur, it is important to have the ECM checked by a qualified mechanic to prevent further damage to the vehicle.

Overall, the engine control module in a Toyota Camry is a critical component that ensures the engine runs smoothly and efficiently. Its ability to monitor and adjust the engine's performance in real-time helps to optimize fuel efficiency and ensure a comfortable driving experience for the vehicle's owner.
