The engine control module (ECM) in a Mercedes-Benz S-Class is a sophisticated computer system that is responsible for controlling various functions of the vehicle’s engine.
This crucial component is also known as the Engine Control Unit (ECU) or Powertrain Control Module (PCM).
The ECM collects data from various sensors located throughout the vehicle, such as the oxygen sensor, throttle position sensor, and engine temperature sensor. It uses this information to calculate the optimal fuel and air mixture ratio, ignition timing, and other parameters needed for efficient engine operation.
One of the key functions of the ECM is to monitor and control the fuel injection system. By adjusting the fuel delivery based on factors such as engine speed, load, and temperature, the ECM ensures that the engine is running smoothly and efficiently.
In addition, the ECM also controls the ignition system, ensuring that the spark plugs fire at the right time to maximize...
