CVT CONTROL SYSTEM: Secondary Pressure Sensor
- The secondary pressure sensor is included in the control valve assembly.
- The secondary pressure sensor detects secondary pressure of CVT and sends a signal to the TCM.
- When pressure is applied to the ceramic device in the secondary pressure sensor, the ceramic device is deformed, resulting in voltage change. TCM evaluates the secondary pressure from its voltage change. Voltage is increased along with pressure increase.
