What are the benz sensors on Mercedes Benz?

Intake pressure benz sensor: It reflects the change of the absolute pressure in the intake manifold, and provides a reference signal to the ECU (engine electronic control unit) to calculate the fuel injection duration;

Air flow meter: measure the amount of air inhaled by the engine and provide it to the ECU as a reference signal for fuel injection time;
Throttle valve position benz sensor: measure the opening angle of the throttle valve and provide it to the ECU as a reference signal for cutting off fuel, controlling fuel/air ratio, and correcting ignition advance angle;
Crankshaft position benz sensor: Detect crankshaft and engine speed, and provide it to ECU as a reference signal for determining ignition timing and working sequence;
Oxygen benz sensor: Detect the oxygen concentration in the exhaust gas and provide it to the ECU as a reference signal to control the fuel/air ratio near the optimal value (theoretical value);
Intake temperature benz sensor: detects the intake air temperature and provides it to the ECU as the basis for calculating the air density;
Coolant temperature benz sensor: detects the temperature of the coolant and provides engine temperature information to the ECU;
Knock benz sensor: It is installed on the cylinder block to detect the detonation condition of the engine, and provides it to the ECU to adjust the ignition advance angle according to the signal.
These benz sensors are mainly used in transmission, steering, suspension and ABS.
Transmission: There are vehicle speed benz sensor, temperature benz sensor, shaft speed benz sensor, pressure benz sensor, etc. The steering device has angle benz sensor, torque benz sensor, hydraulic benz sensor;
Suspension: vehicle speed benz sensor, acceleration benz sensor, body height benz sensor, roll angle benz sensor, corner benz sensor, etc.;
