Vehicle Speed Sensor (Camry 2.4L 4-Cyl.)

Vehicle speed sensor is mounted near rear of transaxle. Vehicle speed sensor outputs a 4-pulse input signal for every revolution of the drive gear in transaxle to the instrument cluster where input signal is converted to a rectangular waveform and then sent to Engine Control Module (ECM). ECM determines vehicle speed by using input signal. ECM may use input signal for controlling fuel injection system, electronically controlled automatic transaxle (if equipped) and various other systems.
