Temperature Sensor
1. The sensor grounding should be reliable, and the sensor wire should not be short-circuited.
2. The thermistor of the moving magnetic water temperature sensor will increase with the temperature and the resistance value will decrease.
Oil quantity sensor
1. The movement of the float in the fuel tank should be flexible, otherwise the indication will be inaccurate due to interference between the float and the fuel tank partition.
2. The oil sensor grounding should be reliable.
3. The resistance of the variable resistance sensor of the moving magnetic fuel gauge will increase as the oil level inside the tank rises.
Speed ​​sensor
1. Make sure that the bottom of the sensor is 0.8 to 1.0 mm away from the engine tip, otherwise misalignment will result. The correct installation method is to first screw the sensor to the bottom, that is, the bottom of the sensor hits the top of the flying tooth of the engine, then rotates counterclockwise two-thirds of the turn, and then fasten with the back nut.
2. The speed sensor output induced voltage Urms>1.0V when idling.
Pressure Sensor
1. The variable resistance value of the moving magnetic pressure gauge increases as the pressure increases.
2. When installing the pressure sensor, do not screw the case directly.
3. If the sensor has an alarm, the sensor line and the alarm line cannot be reversed.
