ENGINE COOLANT TEMPERATURE (ECT) SENSOR [SKYACTIV-D 2.2]

id0140z7006200

Purpose/Function

• Detects the ECT as basic information for mainly determining the fuel injection amount.

• Detects the ECT and inputs it to the PCM as an ECT signal.

Construction

• Installed on the cylinder head.

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

Operation

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

•  PCM restricts engine torque.

•  Increase the idle speed.

•  Inhibits the two-stage turbo control.

•  Inhibits the EGR control.

•  Inhibits the diesel particulate filter regeneration control.

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

•  Inhibits the A/C control.

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

•  PCM restricts engine-transaxle integration control.
