The direct ignition system operates with the help of a magnetic crankshaft position sensor. This sensor protrudes from its mounting socket by approximately 1.3 mm relative to the crankshaft resistor. The resistor is a specially designed wheel attached to the crankshaft or its pulley, which has 58 grooves, 57 of which are spaced at equal intervals of 6 degrees. The last groove is wide enough to generate a "synchronizing pulse". As the crankshaft rotates, the grooves of the resistor change the magnetic field of the sensor, thus creating an inductive voltage pulse. The pulse length of the 58 grooves determines the relative position of the crankshaft and allows the ECM to determine the position of the crankshaft at any given moment. The ECM uses this information to generate ignition timing and injection pulses, which it sends to the ignition coil and fuel injectors.
Removal
1. Disconnect the "-" battery cable.
2. Remove the crankshaft position sensor (CSP) connector from the frame bracket.
3. Remove wire ties if necessary.
4. Remove the CKP sensor mounting bolt.
5. Remove the CKP sensor.
Installation
1. Install the SKR sensor with the mounting bolt.
Tightening: Tighten the crankshaft position sensor mounting bolt to 6.5 Nm.
2. Connect the CKP sensor connector.
3. Secure the wire with cable ties.
4. Connect the "-" wire of the battery.
