The direct ignition system operates with the help of a magnetic crankshaft position sensor. This sensor projects from its mounting socket by approximately 1.3 mm relative to the crankshaft phonic wheel. The specially designed phonic wheel is attached to the crankshaft or its pulley and has 58 grooves around its circumference, 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 phonic wheel change the magnetic field of the sensor, thus creating an induction voltage pulse. Based on the pulse length of the 58th groove, the system recognizes the start of the crankshaft rotation angle and allows the ECM to determine the position of the crankshaft at any time. The ECM uses this data to generate the timing of the ignition and injection pulses.
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 CKP sensor with the mounting bolt. 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.
