DTC 61

CIRCUIT DESCRIPTION
The No. 2 speed sensor detects the rotation speed of the transmission output shaft and sends signals to the Engine Control Module (ECM). The ECM determines the vehicle speed based on these signals. An AC voltage is generated in the No. 2 speed sensor coil as the rotor mounted on the output shaft rotates, and this voltage is sent to the ECM.




The gear shift point and lockup timing are controlled by the ECM based on the signals from this speed sensor and the throttle position sensor signal.
If the No. 2 speed sensor malfunctions, the ECM uses input signals from the No. 1 speed sensor as a backup signal.




DETECTING CONDITION




REFERENCE
Waveform between terminals SP2+ and SP2- when vehicle speed is approx. 60 km/h (37 MPH).
