1 Answers
The crankshaft position sensor on the Audi A6L 2.4 is located in front of the firewall, where there are many connectors such as the mass airflow sensor and oxygen sensors. Functions of the crankshaft position sensor: 1. Detects engine speed to determine fuel injection quantity and ignition timing. 2. Identifies the reference position of the engine's reference cylinder for cylinder sequence discrimination, further determining the position of any piston. 3. Measures the rotation angle of the crankshaft to determine the position of any piston, thereby establishing the ignition and fuel injection timing. 4. In addition to controlling fuel injection and ignition, it is also used for idle speed control, exhaust gas recirculation control, and fuel evaporation control.
