Tyre Pressure Monitoring System is referred to as TPMS. It is a safety feature that is integrated into (or retrofitted onto) the car that tracks your tyre pressure and notifies. You when the pressure in one or more tyres drops to unsafe levels.
Your car’s tyre pressure monitoring system (TPMS) is equipped to alert you if one or more of the tyres are considerably under-inflated and might lead to hazardous driving conditions. On the instrument panel of the dashboard, a yellow sign in the form of a tyre cross-section with an exclamation point flashes when the tyre pressure is low.
How Does TMPS Work?
Today, two major types of systems—Direct TPMS and Indirect TPMS—are in use.
Direct TPMS measures tyre pressure using a sensor positioned within the wheel. The sensor sends a signal to your car’s computer system and activates your dashboard indication light when air pressure falls 25% below the manufacturer’s suggested threshold.
Indirect TPMS works with the wheel speed sensors of your vehicle’s Antilock Braking System (ABS). If the pressure in a tyre is low, it will roll at a different wheel speed than the other tyres. This data is recognised by your vehicle’s computer system, which activates the dashboard indication light.
What Are The Advantages of TPMS?
Preventing underinflated tyres from developing into more serious issues is a key benefit of TPMS. Additionally, you may utilise this technique to manage temperature variations that affect tyre pressure. Correcting low tyre pressure as soon as possible will improve fuel economy, prolong tyre life and improve the stability and safety of your car.
If you see the TPMS alarm on your dashboard, check your tyre pressure right away or visit one of our locations to get your tyres inflated to the prescribed pressure. You should also look for damage to your tyres, such as a puncture, to determine the cause of the air loss. After adjusting tyre pressure, if your alarm is still shown, your TPMS may need to “relearn” or potentially have a TPMS sensor replaced.
How Frequently Should TPMS Sensors be Changed?
5–10 years is a predicted lifespan for TPMS sensors, which are built to survive for many years. Given their price, most drivers will opt to replace TPMS sensors as needed. That is only when their batteries run out or other TPMS parts malfunction. (The onboard computer in your car ought to react and issue a warning of a TPMS issue or failure.)
The Following Are Typical TPMS Problems That Call For Sensor Replacement:
- TPMS sensor battery failure
- Broken TPMS sensors
- The TPMS sensor’s seals and/or gaskets are worn out
- Failure of the TPMS sensor to communicate (many potential reasons)
- The TPMS valve cores or caps freeze up.
Do you Require New TPMS Sensors When You Change Your Tyres?
No not always It is absolutely good to leave the same set of TPMS sensors placed with the wheels. When fitting a new set of tyres because they may outlast a set of tyres, and sometimes even many sets. The TPMS sensors should be checked when the tyres are being serviced. Ask the technician to examine the TPMS sensors and system when you are getting new tyres put.
TPMS Sensor Repair
It takes specialised equipment and training to maintain a vehicle’s TPMS. The valve stem where the air is injected typically has a TPMS sensor attached to it on each wheel. A rubber grommet that seals the air in the tyre and shields the sensor from the elements is located between this stem and the wheel.
The rubber grommet has to be changed, along with the nut that holds the stem and the nickel-plated valve core in the stem, just like the rubber valve stem that was replaced at every tyre change for years since the weather and other conditions caused wear.
The internal parts of the caps are protected by moisture seals because moisture and rust eat away at the stem. All of these parts need to be changed in order to avoid developing a leak while replacing the tyres (or, in tyre speak, the TPMS sensor has to be rebuilt). For providing this service, your installer will often charge a little extra price.
Some cars require “relearning” of the position of each sensor after the tyres have been rotated, therefore there may also be a tiny additional expense associated with rotating tyres depending on the generation and kind of TPMS. To guarantee that the system is functioning effectively, the technician needs specialised expertise, tools, and time. Each vehicle make and model has its own distinct relearning technique.
Conclusion
Maintaining optimum tyre pressure is essential to ensuring the performance and safety of your vehicle’s tyres. Safety and long-term cost reductions are two strong advantages that TPMS offers. We think that the advantages of TPMS greatly exceed the expenses. If your car has TPMS, it’s imperative to keep the system in excellent operating condition or TPMS Replacement Harrow becomes important. An aftermarket system is unquestionably worthwhile to take into consideration if your car lacks an OE TPMS system.
