ENGINE COOLANT TEMPERATURE (ECT) SENSOR [SKYACTIV-X 2.0]
id0140hf006200
Purpose/Function
• Detects the ECT as basic information for mainly determining the fuel injection amount.
• Detects the ECT and sends it to the PCM as an ECT signal.
Construction
ECT sensor No.1
-
• ECT sensor No.1 is located on the cylinder head.
-
• A thermistor has been adopted to the detection area of ECT sensor No.1 for detecting the engine coolant temperature.
ECT sensor No.2
-
• ECT sensor No.2 is located near the water pump.
-
• A thermistor has been adopted to the detection area of ECT sensor No.2 for detecting the engine coolant temperature.
ECT sensor No.3
-
• ECT sensor No.3 is located on the water-cooled charge air cooler.
-
• A thermistor has been adopted to the detection area of ECT sensor No.3 for detecting the engine coolant temperature.
Operation
• Sends the signal, which fluctuates according to the ECT, to the PCM.
