CAMSHAFT SENSOR-INTAKE AND EXHAUST CAMSHAFTSThe "static" Hall sensors are used so that the camshaft positions are recognized once ignitionis “on” - even before the <strong>engine</strong> 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 failsafemode with no VANOS adjustment. The <strong>engine</strong> will still operate, but torque reduction will benoticeable.NOTE: Use caution on repairs as not to bend the impulse wheelsEXHAUSTTWO POSITION PISTONHOUSING WITHINTERNAL/EXTERNALHELICAL GEAR CUPMS MS42 43.0ECMSENSORINTAKEKL 15SOLENOIDVENTSENSORVENTKL 15MS42.0 43.0ECMTWO POSITION PISTON HOUSINGWITH INTERNAL/EXTERNALHELICAL GEAR CUPENGINEOIL SUPPLYSOLENOIDOIL TEMP.SENSORMS MS42.0 43.027M54engMS43/ST039/3/17/00
