CVVL Oil Temperature Sensor
The CVVL oil temperature sensor is located on the front CVVL unit and provides feedback to the PCM on the temperature of the high pressure oil in both CVVL units.
This information is used by the PCM to determine oil viscosity and allows accurate solenoid switching time compensation across a wide engine temperature range -40°C (-40°F) to 150°C (302°F).
The sensor has a two pin connector which provides a temperature signal input to the PCM and a ground connection. The sensor has a NTC element and is specifically calibrated for use at low temperatures. It is possible to remove the CVVL temperature sensor from the assembly if required.
In the event of failure of the CVVL oil temperature sensor, reduced accuracy in control of the CVVL system will occur, resulting in a slight reduction in performance and fuel economy.
