ENGINE COOLANT TEMPERATURE (ECT) SENSOR [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)]

id0140m1006200

Without coolant control valve

Purpose/Function

• Detects the ECT as basic information (mainly used to determine the fuel injection amount) and sends it to the PCM as an ECT signal.

Construction

• Installed to the water outlet case.

ac5uun00003824

• A thermistor has been adopted (as the detecting element) for detecting the ECT.

Operation

• Sends the signal, which fluctuates according to the ECT, to the PCM.

•  Fixes the water temperature for the engine control at 40 °C {104 °F}, and for the idle air control at 80 °C {176 °F}.

•  Operates the cooling fan (high speed rotation).

•  Inhibits the fuel cut control during shift change.
