ENGINE OIL TEMPERATURE SENSOR [SKYACTIV-G 2.5T]
id0140h0256900
Purpose
• The engine oil temperature sensor detects the engine oil temperature mainly as basic information for engine oil variable control.
Function
• Detects the engine oil temperature and sends an engine oil temperature signal to the PCM.
Engine oil temperature sensor characteristic
Construction
• The engine oil temperature sensor is located on the engine oil solenoid valve spacer.
• A thermistor has been adopted for the detection part of the engine oil temperature sensor.
• A thermistor is a resistor element in which changes in the electrical resistance is large against temperature change. Using this characteristic, the sensor detects the engine oil temperature as a resistance value.
• The engine oil temperature sensor is integrated with the engine oil pressure sensor.
Operation
1. The engine oil temperature sensor detects (1) the engine oil temperature.
2. The PCM detects (2) the engine oil temperature based on the voltage from the engine oil temperature sensor.
Fail-safe
• Not applicable
