Why Your RAETON TPMS Light Stays On
The Tire Pressure Monitoring System (TPMS) in your RAETON uses direct sensors mounted inside each wheel. When the warning light stays solid or flashes, it means the system has detected a pressure problem or a sensor fault. Ignoring it can lead to uneven tire wear, reduced fuel economy, or a blowout.
Dead Sensor Battery — The #1 Culprit
Each TPMS sensor has a non-replaceable lithium battery designed to last 5–7 years. If your RAETON is 2018 or older, expect battery failure. Symptoms include:
- Warning light comes on intermittently, then stays solid.
- One specific tire shows no pressure reading on the dashboard.
- The light flashes for 60–90 seconds at start-up, then stays on.
You cannot replace just the battery. The sensor unit is sealed. You must install a new sensor like the BL-ST-089 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Avatr, Changan, Deepal, Mazda, Nevo & 1 More | OE# 3601010CD01, 3601010DG01, 3601010MK02 (433MHz, pre-programmed to OE frequencies).
Signal Interference Diagnosis
A less common but real issue is radio frequency (RF) interference. TPMS sensors transmit at 433MHz (most RAETON models). If you’ve added aftermarket accessories like dashcams, LED light bars, or phone chargers near the steering column, they can block the signal.
How to test: Park the car, turn off all non-essential electronics, and reset the TPMS via the dash menu. If the light clears, the interference source is likely the culprit. Move or unplug the accessory and retest.
Physical Sensor Damage
Road debris, potholes, or improper tire mounting can crack the sensor housing or damage the valve stem. With clamp-in sensors like the BL-ST-089, the metal valve stem can corrode over time, causing slow air leaks that trigger the warning.

How to Confirm the Fault
- Check tire pressures manually with a gauge. If all are correct, the issue is electronic.
- Scan with a TPMS tool (like Autel or Bartec) to read sensor IDs and battery voltage. A reading below 2.4V means the battery is dead.
- Inspect the valve stems for cracks or corrosion — especially on older RAETON vehicles.
- If two or more sensors fail at once, consider signal interference first.
Recommended Part
For a direct replacement, use the BL-ST-089 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Avatr, Changan, Deepal, Mazda, Nevo & 1 More | OE# 3601010CD01, 3601010DG01, 3601010MK02. It is pre-programmed to match RAETON’s 433MHz system and requires no additional cloning. Just install and follow the vehicle’s TPMS relearn procedure (usually a magnet or OBD tool).
FAQ
How do I reset the TPMS light on a RAETON after replacing a sensor?
Most RAETON models use an automatic relearn. Drive above 25 mph for 10–15 minutes. If the light stays on, use a TPMS scan tool or bring it to a shop for a manual relearn.
Can a dead TPMS sensor cause the car to fail inspection?
Yes. In regions with mandatory TPMS compliance (e.g., USA, EU), a warning light is a failure point. Replace faulty sensors before your test.
What happens if I ignore the TPMS warning light?
You risk driving on under-inflated tires, which reduces braking performance, increases fuel consumption, and can cause a blowout at highway speed. Replace the sensor as soon as possible.
Are aftermarket TPMS sensors like BL-ST-089 reliable for RAETON?
Yes. BH-Sens (Baolong Technology) is an OE supplier for many Chinese automakers. The BL-ST-089 meets the same specifications as the factory sensor and is tested for 433MHz frequency accuracy.
