ECM 3408300 M11 Electronic Control Module Engine Spare Parts

What is the ECM?

The ECM regulates four main parts of your vehicle engine's operating systems: air-fuel ratio, idle speed, variable valve timing, and ignition timing. In terms of the air-fuel ratio, the ECM uses sensors to regulate the oxygen to fuel ratio detected in your car’s exhaust to detect an engine rich/lean reading. Some of these sensors include the mass airflow sensor(s), the oxygen sensor(s), air-fuel sensor(s). For the idle speed, the ECM relies on sensors located by the crankshaft and camshaft(s) that track your vehicle’s RPM and engine load by monitoring the speed of rotation of the engine. The variable valve timing system controls when the valves are opened in the engine to either increase power or fuel economy.
