Scheme 1
Type
Oil pressure sensor: Linear Piezo resistive pressure sensor, bridge connected.
Oil temperature sensor: Temperature dependent resistor (Thermistor) of the negative temperature coefficient (NTC) type.
The sensors are integrated in the same component.
characteristic
Oil pressure sensor
Oil temperature sensor: The resistance between terminal #1 and #4 must be 5.7 kohms at +20 °C. the resistance drops with ascending temperature.
