Wheel Speed Sensor, Location 
 
RPM sensors 2 and 3 (Y3/6n2 and Y3/6n3) are permanently connected with the supporting body of the 
electrical control unit (Y3/6) via contact tongues. See Fig. 32

Wheel Speed Sensor, 
 
The signals from the RPM sensors 2 3 (Y3/6n2, Y3/6n3) are recorded in the ETC control module (N15/3) 
together with the wheel and engine speeds and other information, and are the input signals for the 
electronic control system.

Operation  

The RPM sensors are pressed against the transmission housing (51) by a spring (49) which is held against the 
valve housing of the shift plate (2a). See Fig. 33. This ensures a defined distance between the RPM sensors and 
the exciter ring (50). RPM sensor 2 (Y3/6yn2) records the speed of the front sun gear via the outer multiple-disc 
carrier of the front multiple-disc clutch (K1b) and RPM sensor 3 (Y3/6yn3) records the speed of the front 
planetary gear carrier via the inner multiple-disc carrier of the front multiple-disc clutch (K1c).
