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.
