The continuous maturity of new energy vehicle technology has greatly reduced the emissions of vehicle pollution. The function of the new energy vehicle temperature sensor is to detect the temperature of the vehicle well, transmit the information to the vehicle air conditioner and other equipment, control the temperature of the vehicle within a reasonable range, and ensure the safety of the vehicle and the people in the vehicle.
How does the coolant temperature sensor of the new energy vehicle temperature sensor judge whether it is working smoothly?
Do you know what is the transmission oil temperature sensor in the new energy vehicle temperature sensor?
What is the coolant temperature sensor of the new energy vehicle temperature sensor?
The engine coolant temperature sensor is short-circuited, and the data stream will display a high temperature above 100°C, causing the mixed steam to be too thin to start; the sensor is open or the grounding wire is poorly connected, and the data stream will display a low temperature below -30°C, causing the mixed steam to be too thick, The exhaust pipe emits black smoke.
The OBD-I system sets the engine control unit to limit the temperature of the coolant temperature sensor to between -35~120℃. If it exceeds or falls below this range, the control unit can determine that the sensor is malfunctioning, but it will not be within this range. A fault code has occurred. If the coolant temperature sensor is short-circuited, the data stream shows that the coolant temperature exceeds 100°C when the ignition switch is turned on, but since it has not reached 120°C, no fault code will be left.
The transmission oil temperature sensor is installed on the baffle in the oil pan of the automatic transmission. It is mainly used to detect the temperature of the transmission hydraulic oil, as an electronic control unit as the basis for shift control, oil pressure control, and lock-up clutch air. Its inside is mainly a negative temperature coefficient semiconductor thermistor, the higher the temperature, the lower the resistance. Its resistance changes with temperature. The computer measures the temperature of the hydraulic oil of the automatic transmission according to the change of its resistance.
The coolant temperature sensor terminal is 2-pin, one is the input signal line, and the other is the output signal line; if the terminal is 4-pin, the 4-pins are the input signal line, output signal line, control unit ground wire, and instrument panel respectively. Ground wire, as shown in Figure 2. The coolant temperature sensor is generally installed at the thermostat or radiator outlet on the rear side of the engine and is responsible for the control of fuel injection pulse width, warm-up, ignition advance angle, automatic transmission torque converter lock, and overspeed gear, and air conditioning.
The increasing advancement of science and technology has allowed the updating and upgrading of various parts of the car. The continuous innovation of temperature sensors for new energy vehicles has increasingly met the requirements of vehicle owners for vehicle detection temperature performance, which not only strengthens the performance of the vehicle but also ensures the safety of the occupants in the vehicle.
