water temp receiver gauge resistor 1984 toyota pickup

• 2022-11-01

The 1984 toyota pickup water temp gauge resistor sensor is located at the thermostat behind the engine cylinder head. If the water temperature gauge sensor is damaged, it will cause the water temperature gauge to remain at the same height all the time, resulting in the wrong judgment of the owner. If the 1984 toyota pickup water temp gauge resistor sensor is damaged, it needs to be replaced in time, otherwise the driving safety of the vehicle will be affected. If the water temperature sensor of the car is broken, there will be a mixture that can only supply thinner gas to the engine (the signal when the car is hot). It is difficult to start the engine when it is cold.

The 1984 toyota pickup water temp gauge resistor sensor is generally installed on the water channel and water tank of the car. The automobile water temperature sensor is installed on the water jacket of the engine block or cylinder head, which is in direct contact with the coolant and can be used to measure the engine coolant temperature. The function of the water temperature sensor is to convert the temperature of the cooling water into a signal, which is then transmitted to the computer controller to correct the fuel injection quantity. 1. Increase the fuel injection quantity when the temperature is low; 2. Correct the ignition advance angle, increase the ignition advance angle at low temperature, and delay the ignition advance angle at high temperature; 3. Control the idle speed control valve to increase the speed at low temperature.

If the 1984 toyota pickup water temp gauge resistor sensor of the car is broken, there will be symptoms such as the pointer of the water temperature gauge pointing to the maximum, the pointer will not move, weak acceleration, difficult cold start or water temperature failure. When similar symptoms occur, you should go to the maintenance shop for maintenance as soon as possible. The most common cause of water temperature sensor failure is poor contact, while the less common causes are open circuit and short circuit. The water temperature sensor of the car is broken and has the symptom of inaccurate water temperature detection. It should be noted that the water temperature sensor is the original electronic device in the automobile circuit. If the equipment fails, there is not much maintenance space, so it must be replaced.
