water temp receiver gauge 1984 toyota pickup

The 1984 toyota pickup water temp receiver is working with the water temp gauge , it detects the temperature of the coolant. If the water temp receiver gauge 1984 toyota pickup of the automobile breaks down, there will be symptoms such as the pointer of the water temp gauge reaches the maximum, the pointer will not move, the acceleration is weak, the cold start is difficult, or the water temperature does not come up. When similar symptoms occur, you should go to the maintenance shop for maintenance as soon as possible.

The 1984 toyota pickup water temp receiver is installed on the water jacket of the cylinder head and directly contacts with the cold water to directly measure the temperature of the engine cooling water. If the water temperature sensor fails, the engine ECU cannot detect the signal of the water temp sensor receiver. At this time, in order to protect the 1984 toyota pickup engine, a substitute value of water temperature will be input, which will lead to abnormal water temperature and abnormal engine operation.

The 1984 toyota pickup water temp gauge receiver is a semiconductor thermistor. When the temperature is low, the resistance is larger, and when the temperature is high, the temperature is smaller. The detection method of the 1984 toyota pickup water temp gauge receiver is to use a multimeter to detect. When the water temperature sensor is heated by an electric hair dryer, the heating resistance will become smaller under normal circumstances. If it does not become smaller, the water temperature sensor has failed. The most common cause of water temperature sensor failure is poor contact, and the less common cause of failure is open circuit and short circuit.

When a container with a water temp receiver sensor is used, the water level sensor in the container converts the cooling water temperature into an electrical signal and feeds it back to the driving computer of the vehicle. At this time, ECU will adjust the control unit in time according to the data stored in advance and the feedback signal.The water temperature sensor contains an NTC thermistor, which changes with the change of the cooling water temperature, so that the corresponding water level signal can be measured more accurately. Then, according to the deviation from the set signal, the ECU can judge the working condition of the engine in time, and then correct the fuel injection amount and ignition advance angle of the 1984 toyota pickup.
