FUEL TEMPERATURE SENSOR [SKYACTIV-D 2.2]

id0140z7256500

Purpose/Function

Fuel injector (2pin type)

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

• Detects the fuel temperature in the fuel supply line and sends it to the PCM as the fuel temperature signal.

Fuel injector (6pin type)

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

• Detects the fuel temperature in the fuel supply line and inputs it to the PCM as a fuel temperature signal.

Construction

Fuel injector (2pin type)

• Fuel temperature sensor is installed in lower case.

ac5wzn00001640

• A thermistor has been adopted as the detecting element for detecting the fuel temperature in the fuel supply line.

Fuel injector (6pin type)

• Built into the fuel injector.
