ELECTRICAL SYSTEM CONTINUED
Position Sensor (Forward/Neutral/Reverse)
0008
The position sensor for the direction control handle continuously informs the ECM of the position of the
transmission direction control lever. The three positions that can be selected are the FORWARD (F) position, the
NEUTRAL (N) position, or the REVERSE (R) position. The ECM uses the duty cycle of the signal in order to
determine the transmission directional clutch that must be engaged. The duty cycle of the sensor signal increases
as the direction lever is turned to the FORWARD position and decreases as the direction lever is turned to the
REVERSE position. The reverse direction switch acts as a backup for the position sensor in the event that the
position sensor fails.
