Motronic ME 7.1.1
Engine Run-Down
The CMP Sensor 2 G163 is used to monitor camshaft
adjustment and to generate a substitute signal if the
CMP Sensor G40 fails.
The ECM remains active for a defined time after the
ignition has been turned off and, with the aid of the
RPM Sensor G28, monitors the engine as it slows to
a stop.
The position of the engine mechanical components
(position of the next cylinder at ignitionTDC) is stored
and is available the next time the engine is started.
The ME 7.1.1 can immediately begin injection and has
a fuel mixture ready, which results in faster starting.
The CMP Sensor G40 is mounted to
cylinder bank 2.
The CMP Sensor 2 G163 is mounted to
cylinder bank 1.
