Where is the cv03 water temperature sensor of Dongfeng Junfeng?
The water temperature and water level sensor of Dongfeng Junfeng CV03 automobile is a constant temperature part and a water level control part. The water level sensor of Dongfeng Junfeng automobile transmits the sensed water level signal to the controller of the automobile. The computer in the controller of Dongfeng Junfeng automobile compares the measured water level signals, and finally obtains a certain deviation, and gives instructions to make the water level reach the standard state.
After the water intake program of Dongfeng Junfeng automobile is completed, the main engine of the temperature control part sends an "on" command to the electric valve of the automobile supplying heat medium, and the system starts to heat the water in the automobile container. When heated to a certain temperature. The controller of the automobile sends out the instruction to close the valve and cut off the heat source, so that the automobile system enters the heat preservation state.
Extended data:
The water temperature sensors of Dongfeng Junfeng Automobile are classified as follows:
The function of the first water temperature sensor is relatively simple, that is, through the change of internal resistance and the change of current, the sensor drives the change of water temperature meter to indirectly tell the working temperature of the engine.
Secondly, the water temperature sensor has no change in structure, but its function is to provide an analog signal of temperature change to the engine control unit. The power supply voltage provided by the control unit is 5V, and the signal returned to the control unit is a linear change signal of1.3v-3.8V. ..
However, these two water temperature sensors work under different voltage conditions. The sensor of the water temperature meter is 12V, while the sensor of the engine control unit is 5V, so they are not interchangeable. Besides, the shape of the plug itself is different. The difference is simple. The former has only one wire in the plug, while the latter has two wires in the plug of the engine control unit.
Phoenix. Com- When the water temperature is turned on, the fault light is repeatedly misdiagnosed.
