Forklift-specific sensors are input devices for forklift electrical systems. They convert various operating information during forklift operation, such as forklift speed, temperature of various media, operating conditions of forklift engines, etc., into electrical signals and transmit them to the forklift main board/control board so that the engine is in the best working condition. Forklifts use many sensors. When judging the fault of forklift sensors, we should not only consider the sensor itself, but also the entire circuit where the fault occurs. Therefore, when finding the fault, in addition to checking the sensor, we should also check the wiring harness, connectors, and related circuits between the sensor and the electronic control unit.
The sensors of forklifts are as follows:
1. Crankshaft speed sensor, used to detect engine speed and determine the top dead center of one (four) cylinders;
2. Crankshaft position sensor (crankshaft angle sensor);
3. Water temperature sensor, used to detect engine coolant temperature (provide engine temperature signal);
4. Accelerator pedal position sensor, used to detect accelerator pedal position;
5. Wheel speed sensor, used to detect wheel speed;
6. Vehicle speed sensor, used to detect vehicle speed;
7. Forklift engine coolant level sensor;
8. Forklift engine coolant temperature sensor;
9. Forklift engine oil pressure sensor;
10. Throttle position sensor;
11. Fuel level sensor;
12. Fuel temperature sensor;
13. Oil pressure sensor;
14. Steering sensor;
15. Lift sensor;
16. Rotation sensor;
17. Motor speed sensor.
