Vehicle Speed Sensor: Description and Operation

The Vehicle Speed Sensor is a small signal generator that is turned by a gear inside the transaxle assembly. In this way, the Vehicle Speed Sensor produces a signal that is proportional to vehicle road speed.

The Vehicle Speed Sensor supplies a signal to all components that require vehicle speed information: the Speed Control Amplifier (on Speed Control-equipped vehicles), the 4EAT Control Module (on automatic transaxle-equipped vehicles).
