Revotron 1.2T 151 v. Crankshaft Position Sensor : Component Details : The circuit decodes the signal given by an inductive based sensor (Variable Reluctance). Intended target is a wheel uniformly cut with 60 teeth and 2 teeth removed. The sensor output signal approximates a sine wave whose frequency is proportional to engine speed and amplitude is approximately proportional to engine speed. Active edge is generated from zero crossing point positive to negative transition. Component Location : Preliminary Checks : 1. Loose/Damaged Connections between sensor and EMS ECU. 2. Check for back out of pins at both sensor connector and ECU connector. 3. Check for damage of pins at both sensor connector and ECU connector. 4. Check the continuity from sensor connector pins to the ECU pins. 5. Physical damage to flywheel. 6. Improper Air Gap between sensor and flywheel.
