FUEL PRESSURE SENSOR [SKYACTIV-D 2.2]

id0140z7006100

Purpose/Function

• Detects the fuel pressure in the fuel supply line as basic information for mainly determining the fuel injection amount.

• Detects the fuel pressure in the common rail and inputs it to the PCM as a fuel pressure signal.

Construction

• Built into the fuel injector.
