The Engine Control Module (ECM) in your 1994 Chevy Silverado controls various engine functions, including fuel injection, ignition timing, and emissions management. It processes data from sensors throughout the vehicle to optimize performance, fuel efficiency, and emissions. The ECM also helps in diagnosing issues by generating trouble codes when problems are detected within the engine or related systems. Overall, it plays a crucial role in ensuring smooth operation and compliance with environmental standards.
