ENGINE OIL PRESSURE SENSOR [SKYACTIV-D 2.2]

id0140z7257000

Purpose/Function

• Detects the engine oil pressure as basic information for mainly intake stroke EGR using double exhaust valve actuation system (IDEVA) control and idle speed control.

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

Construction

• Built into the engine oil temperature sensor/engine oil pressure sensor.

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

Operation

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

•  PCM restricts engine torque.

•  The fast idle up correction for the idle speed control is inhibited.

•  Inhibits engine-stop by operating the i-stop function.

P0523:00

•  PCM restricts engine torque.

•  The fast idle up correction for the idle speed control is inhibited.

•  Inhibits engine-stop by operating the i-stop function.
