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.

B2192 ID discord, IMMU-ECM
Description
BCM performs the ID verification with ECM that allows the
engine to start. Start the engine if the ID is OK.
ECM prevents the engine from starting if the ID is not registered. BCM starts
the communication with ECM if
ignition switch is turned ON.
