When your tire pressure light remains illuminated after filling your tires, this usually indicates one or more sensors are miscommunicating with the car and need readjusting accordingly. As such, double check with a tire gauge that your air pressure matches up correctly to the proper PSI settings for each tire.
1. Low Pressure
TPMS lights are intended to inform you when one or more of your tires has lost pressure, prompting a warning light to illuminate. Should this occur, pull over in a safe location and use a tire gauge to check each tire’s pressure; aim for inflation according to manufacturer recommendations, typically found on placards located inside your driver’s door frame or your owner’s manual.
Temperature changes can dramatically alter tire pressure as cold air contracts and warm air expands, altering its distribution across tires. If your TPMS light remains illuminated after refilling and rechecking pressure on all four tires, this could indicate sensor issues requiring service center inspection. Contact us for more details.
2. Bad Sensor
Your Tire Pressure Monitoring System, commonly referred to as TPMS light, is intended to alert drivers when one or more tires have low air pressure. This feature helps prevent tires from becoming under or over-inflated, improving fuel economy and vehicle handling as a result.
But sometimes TPMS warning lights appear for reasons other than low pressure. For instance, their sensors could activate during extreme cold temperatures due to contraction of air within your tires.
An effective solution to quickly reset the sensor is by placing your ignition key into “On”, but without starting the engine. Locate and press and hold on the TPMS reset button located beneath your steering wheel until its light blinks three times before releasing.
3. Bad Battery
If the TPMS light remains illuminated after inspecting all tires (including your spare) with a pressure gauge and they meet recommended levels, but your sensor remains malfunctioning, it could be wear and tear damage that is impacting its functionality – gaskets, seals or valve caps often wear over time; additionally, small batteries used by sensors tend to degrade over time as well.
Long periods of high-speed driving can cause tire heat expansion to alter pressure readings and set off an TPMS warning light, which requires professional reset to resolve.
To reset a tire pressure monitoring system (TPMS), first turn your vehicle off and disconnect its battery with a wrench. Once on, turn up the car’s horn for three seconds while honking for about 15 times before reconnecting the battery. This will release any stored energy that remains within its sensors.
4. Faulty Valve Stem
An incorrectly functioning or damaged valve stem can create air leaks and lower tire pressure, leaving tires vulnerable. Metal valve stems may corrode in areas with road salt; rubber ones may crack or dry rot over time. When one leaks air from its tire pressure monitoring system, you might hear hissing noises or see bubbles when spraying soapy water onto it.
Maintain regular inspection of both tires and valve stems to detect any problems with them, including any potential for low tire pressure, fuel economy problems or flat tires caused by defective valve stems. If any problems with them do arise, have them immediately replaced by a certified Subaru technician; using tire sealant on the valve stem might provide temporary relief but is no permanent solution.
5. Damaged Tire
TPMS light still illuminated after checking air pressure? Professional inspection may be in order. Tires must be thoroughly inspected for signs of damage such as punctures that cannot be repaired but will need replacing instead.
Understanding why your tire pressure warning light keeps coming on can be distressing, but understanding why will help you address the issue swiftly and easily. Resetting your TPMS system and replacing any tires with dry rot or other damage are effective measures for providing reliable tires from Jackson to Ridgeland drives! Les Schwab offers this service at all of their locations nationwide.
6. Damaged Valve
Sometimes the TPMS light will come on and remain illuminated even though tires are properly inflated. This could happen for several reasons; temperature swings could cause the tire to lose or gain air, exceeding its lowest limit and triggering the sensor. Metal valve stems exposed to salt or road chemicals could corrode too, prompting it to stay illuminated.
If the Tire Pressure Monitoring System (TPMS) light remains illuminated after filling your tires, consult Wilson KIA service experts for tips to reset and keep them properly inflated. By doing so, you can enjoy safer driving while optimizing fuel economy and getting maximum mileage out of each tire; appropriate inflation also reduces wear-and-tear costs; ultimately saving money over replacement costs.
7. Damaged Tire
Sometimes your tire pressure monitoring system (TPMS) light may remain illuminated even though your tire pressures have stabilized, suggesting a sensor issue; such sensor units typically last 9 years before needing replacement.
TPMS could also signal tire damage. Punctures or cuts are easily repairable, while damage such as bulges or blisters must be addressed immediately to ensure optimal safety for you and others on the road.
If the Tire Pressure Monitoring System (TPMS) light is still illuminated after filling your tires, make sure they have reached optimal pressure with a reliable gauge (refer to owner’s manual or sticker on inside driver door for recommendations). If pressure checks out as expected but TPMS light still refuses to turn off, consider having professional sensors checked out as soon as possible.
