Camshaft Sensor

Camshaft Sensor - Intake and Exhaust Camshafts







The "static" Hall sensors are used so that the camshaft positions are recognized once ignition is "on" - even before the engine is started.

The function of the intake cam sensor:
- Cylinder bank detection for preliminary injection
- Synchronization
- Engine speed sensor (if crankshaft speed sensor fails)
- Position control of the intake cam (VANOS)

The exhaust cam sensor is used for position control of the exhaust cam (VANOS)

If these sensors fail there are no substitute values, the system will operate in the failsafe mode with no VANOS adjustment. The engine will still operate, but torque reduction will be noticeable.


NOTE: Use caution on repairs as not to bend the impulse wheels
