Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Vehicle Speed Sensor (At Transmission/Transaxle)
On some models, vehicle speed sensor is mounted near rear of transaxle/transmission. Vehicle speed sensor outputs a 4-pulse input signal for every revolution of drive gear in transaxle/transmission to 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 and may use input signal for controlling fuel injection system and electronically controlled automatic transaxle/transmission (if equipped).
