Distance (Speed) Sensor

This sensor is located on transaxle extension housing. The sensor generates 8 pulses per axle shaft revolution. The SMEC will interpret distance (speed) sensor input along with throttle position sensor closed throttle input.

This will allow SMEC to differentiate between closed throttle decel and closed throttle idle (vehicle stopped) conditions. During decel, SMEC controls Automatic Idle Speed (AIS) motor to maintain a desired manifold absolute pressure value. During idle (vehicle stopped), the SMEC controls AIS motor to maintain a desired idle speed.
