How to deal with the tire pressure monitoring system failure in Haval H6?
4 Answers
Haval H6 tire pressure monitoring system failure solutions are: 1. Get off the car to check and confirm whether the tire condition is normal and if there is any air leakage; 2. Pull out the key and reinsert it to start; 3. If there is still no tire pressure monitoring, you can start the vehicle and drive at low speed for about five minutes; 4. Remove the negative terminal of the car battery, wait a few minutes, then reinstall it and insert the key to reset the central control; 5. Replace the battery. Taking the 2021 Haval H6 as an example, it belongs to the compact SUV category, with body dimensions of: length 4615mm, width 1860mm, height 1720mm, wheelbase of 2680mm, fuel tank capacity of 58l, and curb weight of 1675kg.
My Haval H6 also experienced a tire pressure monitoring system (TPMS) warning alarm once, which really worried me. I first parked and turned off the engine, waited a few minutes, and then restarted the car to try resetting the system, but the light remained on. So I got out to check all tire pressures. Using the onboard tire pressure gauge, I found the left front tire was significantly underinflated, and then I remembered passing through a construction site the day before where a nail might have punctured it. I quickly drove to a nearby repair shop to fix the tire. The mechanic said the sensor was fine and the system might have triggered a false alarm due to the tire leak. After the tire was repaired, the warning disappeared. Since then, I’ve developed a habit of manually checking tire pressure regularly, as unstable tire pressure is too dangerous on highways—it can lead to blowouts or increase braking distance. The Haval H6’s system can sometimes be overly sensitive, so it’s better to have the sensors calibrated by the 4S shop during regular maintenance.
Don't panic when the tire pressure warning light turns red—here are some practical tips. First, park your car and manually check each tire's pressure with a gauge. The standard pressure for a Haval H6 is usually marked on the sticker inside the driver's door frame, typically around 2.3 to 2.5 bar. If the pressure is normal, try turning the engine off and restarting it, then hold down the system reset button (usually near the steering wheel) to see if it resets. If the warning persists, it might be due to a dead sensor battery or wiring issues—Haval H6 sensors are prone to aging, and replacing one costs about 100-200 yuan. Keep your tires clean to avoid dirt clogging the sensors, and slow down when driving over large potholes to extend the system's lifespan. Don't ignore the warning—low tire pressure increases fuel consumption and is dangerous. If you can't fix it yourself, visit a 4S shop for professional diagnostics—it's simple and safe.
Tire pressure system issues can stem from various causes. Sensor batteries typically deplete within 3 to 5 years, and wireless sensors used in Haval H6 are prone to moisture or interference. Alarms may trigger from punctures by sharp objects or long-term pressure imbalance. Poor wiring connections are another common factor, especially when high-pressure car wash jets hit the interfaces. Outdated system software can also cause false alerts, so regular firmware updates at authorized service centers are recommended. Upon detecting a fault, immediately check actual tire pressure to mitigate risks, as improper pressure leads to premature tire wear or even loss of control. Prioritize driving safety during troubleshooting, and replace faulty sensors promptly to prevent long-term hazards.
