ENGINE OIL PRESSURE SENSOR [SKYACTIV-D 1.5]

id0140z5257000

Purpose/Function

• Detects the engine oil pressure as basic information for mainly idle speed control.

• Detects the engine oil pressure and sends it to the PCM as an engine oil pressure signal.

Construction

• Installed on the cylinder block.

• A semiconductor strain gauge has been adopted to the engine oil pressure sensor (as the detecting element) for detecting the engine oil pressure.

• The engine oil pressure sensor is integrated with the engine oil temperature sensor.

Operation

• Sends the signal, which fluctuates according to the engine oil pressure, to the PCM.
