This document must not be used in any w ay, such as copying and redistributing to third parties, w ithout our consent Step 5 Check the CAM connector for any damage - Step 6 Check the timing belt. Check whether the setting of timing is correct. Correct it, if abnormal. - Step 7 Check the CAM flag on the cam shaft for any damage or foreign deposits - Step 8 Check sensor physically. Check for any foreign particles sticking to the sensor and clean it. - Step 9 Check crank sensor physically, crank sensor air gap, crank sensor connector, crank sensor continuity with ECU Crank sensor air gap (0.5mm to 1.5mm) Step 10 Check the CAM sensor physically. Replace the sensor, if found damaged - Associated Parameters: Parameter Label Description DID Monitoring Crank synchronisation enabled Label displaying the synchronization of CAM and Crank FE5D True if the crank and cam synchronisation is done Verification condition: Drive the vehicle in city and highway condition for 20 mins. Circuit Description: ECM senses the Cam shaft position with the help of Cam Shaft Position Sensor. The sensor is Hall Effect type. The direction of the magnetic field emitted from the sensor magnet changes according to the tooth position present in the cam shaft, this variation in the magnetic field varies the output voltage of the cam sensor that is used to find the position of the cam shaft.
