HOMAN H3 Air Pressure Sensor LG9704710014 FROM SINOTRUK COMPANY
FUNCTION
1. Real-time Compressed Air Pressure Monitoring: Precisely senses the air pressure within the vehicle's pneumatic braking system.
2. Signal Conversion and Transmission: Converts physical pressure values into electrical signals, transmitting them to the vehicle's dashboard and ECU via a 3-pin connector.
3. Dashboard Display and Alarming: Displays the braking system's air pressure values to the driver in real time. Should the air pressure drop below a safe threshold, it triggers the dashboard's air pressure warning light or buzzer, alerting the driver to take immediate action and preventing brake failure caused by insufficient air pressure.
Installation Location
It is installed directly onto the air reservoir-typically at a dedicated port located on the top or side of the main brake reservoir or the auxiliary reservoir.
Alternatively, it is situated in the mid-to-rear section of the vehicle frame's right side, or at a critical junction within the chassis's pneumatic system; positioned near the rear of the cab or in the vicinity of the fuel tank, it is installed in a cluster alongside other air reservoirs.

Routine Maintenance Recommendations
1. Daily (Before Vehicle Operation):
Observe the dashboard air pressure gauge to ensure the reading is normal.
Check whether the air pressure warning light is illuminated or flashing; if any abnormality is detected, inspect the system immediately.
2. Weekly (or Every 1,000–2,000 km):
Visually inspect the sensor connector plugs for looseness, oxidation, or dirt accumulation.
Check the area surrounding the sensor mounting location for traces of oil, water, or corrosion.
3. Monthly (or Every 5,000–10,000 km):
Wipe down the sensor housing and connector plugs with a clean, dry cloth to keep them clean and dry.
Inspect the connecting wiring for any signs of damage, aging, or rodent bites.
Verify that the air reservoir drain valve is functioning correctly (to prevent excessive water accumulation from adversely affecting the sensor's operating environment).
