What Causes the Tire Pressure Monitoring System Not to Display Tire Pressure?
3 Answers
If there is a response when stationary but not while driving, the reasons could be low transmission strength, insufficient receiver sensitivity, or interference. If there is no response when stationary and pairing fails, it indicates a transmitter failure or low signal transmission strength, which can usually be resolved by changing the placement position. Below are some additional details about tire pressure monitoring: 1. The module battery is depleted; replace the entire tire pressure monitoring module. 2. The module inspection port is blocked by something, preventing detection. 3. Pairing failure; re-pairing is required. Some models can do this independently, but most require professional pairing at a 4S shop. 4. The module is damaged; replace it with a new one.
When my tire pressure monitoring system doesn't display tire pressure, common issues include sensor battery depletion – each wheel sensor has a battery with a lifespan of about 5 to 10 years, and once it runs out of power, the signal can't be transmitted; sensor damage or water ingress is also not uncommon; the system might have forgotten to learn, especially after installing new tires which require re-pairing; other problems like poor antenna reception or vehicle computer faults can cause signal loss; even the car's overall battery voltage being too low might affect the display. It's best to first try replacing the sensor battery, and if that doesn't work, take it to a professional shop for a comprehensive check to avoid accidents caused by sudden tire deflation while driving. Regularly check tire pressure manually; even if the system doesn't display it, you can still top up the air in time.
Don't panic if your tire pressure monitoring system isn't displaying – I've encountered this several times before. Most often, it's because the sensor's battery is dead or the sensor itself has aged; it could also be that the vehicle's system wasn't initialized correctly – try restarting it. Sometimes, extreme cold or hot weather affects battery performance. Check your car's manual to see how to re-pair the sensors, and if needed, ask a friend to help read the fault codes. Driving with incorrect tire pressure is much more dangerous if not fixed promptly, as it could lead to blowouts or veering. I recommend carrying a simple tire pressure gauge to manually check the pressure, at least to ensure safety.
