Distance (Speed) Sensor

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

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