Camshaft Position Sensor: Description and Operation

CAMSHAFT POSITION MONITORING

General Description
The angle misalignment diagnosis is partitioned in two parts

Part 1: Reference adaptation of the camshaft position
- The reference adaptation will be executed at the end of production line or by tester
- Angle of misalignment are stored in EEPROM over whole engine life, angle limitation ± 5 degrees crank angle. Misalignment over ± 5 degrees crank angle will be added to the adaptation correction in part 2.
- Purpose: adaptation of particular tolerances, which are engine specific and constant (phase sensor + trigger wheel)

Reference adaptation






Part 2: Adaptation of the camshaft position during driving
- Running during driving if camshaft is in dead (unpowered) position
