Description
Exhaust valve timing control position sensor detects the concave groove of the exhaust camshaft rear end.
This sensor signal is used for sensing a position of the exhaust camshaft.
This sensor uses a Hall IC.
Based on the position of the exhaust camshaft, ECM controls exhaust valve timing control magnet retarder to optimize the shut/ open timing of exhaust valve for the driving condition.

Sliding sensor
Description
The sliding sensor is installed to the seat frame.
The pulse signal is input to the driver seat control unit when sliding
is performed.
The driver seat control unit counts the pulse and calculates the sliding
amount of the seat.
