EC-26 < SYSTEM DESCRIPTION > [HR16DE] COMPONENT PARTS BATTERY TEMPERATURE SENSOR Battery temperature sensor is integrated in battery current sensor. The sensor measures temperature around the battery. The electrical resistance of the thermistor decreases as temperature increases. <Reference data> *: These data are reference values and are measured between battery temperature Malfunction Indicator Lamp (MIL) INFOID:0000000009020596 The MIL is located on the combination meter. The MIL will illuminate when the ignition switch is turned ON without the engine running. This is a bulb check. When the engine is started, the MIL should turn OFF. If MIL remains ON or continues blinking, the on board diagnostic system detects a DTC(s) that affects exhaust gas. For details, refer to EC-57, "DIAGNOSIS DESCRIPTION : Malfunc- . Mass Air Flow Sensor INFOID:0000000009020597 The mass air flow sensor (1) is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. The mass air flow sensor controls the temperature of the hot wire to a certain amount. The heat generated by the hot wire is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the electric current supplied to hot wire is changed to maintain the temperature of the hot wire as air flow increases. The ECM detects the air flow by means of this current change. Oil Pressure Warning Lamp INFOID:0000000009020598 Oil pressure warning lamp is located on the combination meter. It indicates the low pressure of the engine oil and the malfunction of the engine oil pressure system. Combination meter turns the oil pressure warning lamp ON/OFF according to the oil pressure warning lamp signal received from ECM via CAN communication.
