CVT CONTROL SYSTEM: Secondary Speed Sensor
- The secondary speed sensor is installed in the rear of transaxle assembly.
- The secondary speed sensor detects the secondary pulley revolution speed and sends a signal to the TCM.
- The secondary speed sensor generates the ON-OFF pulse (short waveform) in proportion to the rotating body speed which is "The higher the rotating body speed is, the faster the change cycle is". The TCM judges the rotating speed from the changing cycle of this pulse signal.
