yamaha nytro water temp gauge sensor install

How to install the motorcycle yamaha nytro water temp sensor and the water temp gauge? The water temp gauge should have three wires and three colors, a (power supply positive), B (ground supply negative), C (sensor wire). During commissioning, connect the positive pole and negative pole of the power supply to both ends of the battery respectively, and short circuit the sensor wire and the negative pole wire.

When there is no short circuit, the pointer is at the low temperature. After the short circuit, the pointer is at the highest temperature. This means that the debugging is correct, and the sensor wire can be connected to the temperature sensor probe.

Generally speaking, the thermostat is installed at the water outlet on the upper part of the engine; The water temperature sensor is installed on the engine block behind the thermostat, that is, between the water pump and the thermostat. The engine temperature sensor of the yamaha nytro motorcycle is installed on the cylinder block of the engine. It can only be seen by removing the fan cover outside the engine block. A component with wires installed on the cylinder block, below which is copper, is installed on the cylinder block with screw threads. It is a temperature sensor.

The temperature control switch cannot be connected with the water temperature gauge. The temperature control is to control the start of the cooling fan. Generally, the sensor of the water temperature gauge is directly connected to the water temperature gauge with a wire. The two wires of the two-wire water temperature sensor of the motorcycle are the instrument wire and the grounding wire respectively. The two wires do not need to be distinguished, that is, just connect one wire as the instrument wire and connect it to the water temperature instrument.

The function of motorcycle temperature sensor is to detect the engine temperature in real time and transmit it to ECU in the form of electric signal. ECU changes the fuel injection quantity (fuel injection pulse width) according to the change of electrical signal, which cannot be removed.

When the water temperature sensor fails, the temperature signal of the hot vehicle is often displayed when the cold vehicle starts. ECU cannot get the signal of providing too rich mixture, and can only supply the thinner mixture of the engine, so it is difficult to start the engine when the engine is cold. The water temperature sensor is faulty, and the water temperature gauge is unstable or does not move. The water temperature sensor is installed on the water channel and water tank of the car, and the temperature control switch is installed on the water channel.
