Why does the tire pressure warning light keep coming on in the 10th-generation Accord?
3 Answers
Tire pressure monitoring indicator light keeps illuminating for the following reasons: 1. Tire puncture causing the TPMS light to activate. Use a tire pressure gauge to measure; if pressure is low, refill it and then observe the warning light. If it lights up again after a few days, the tire needs to be removed for inspection. 2. Sometimes the TPMS light indicates excessive tire pressure. International standards specify that passenger car tire inflation pressure should be: standard tires between 2.4-2.5 bar; reinforced tires: 2.8-2.9 bar; maximum pressure: should not exceed 3.5 bar. Therefore, when any tire exceeds 3.0 bar, it may trigger the TPMS warning light. 3. Prolonged driving with low tire pressure causing TPMS activation. If a tire's pressure is too low, high-speed operation increases tire temperature, subsequently raising pressure. In this case, promptly stop to rest or replace with a spare tire. 4. TPMS light activation due to prolonged lack of inflation causing low pressure. When pressure drops below 1.8 bar, the TPMS warning light will activate.
I've been driving a 10th-generation Accord for several years and often encounter the issue of the tire pressure warning light frequently coming on, which can be quite annoying at times. There are quite a few common reasons for this, such as an actual tire leak—maybe a nail caused a slow deflation. Or it could be that the tire pressure monitoring sensor is faulty or out of battery; those things buried in the tires eventually run out of power after prolonged use. Weather changes also affect air pressure, causing the light to come on randomly due to thermal expansion and contraction. Another issue is improper system reset—if you don’t drive the car after inflating the tires to let it recalibrate, the light will keep flashing. The most frustrating part is that a constantly illuminated warning light can lead to wasted fuel, uneven tire wear, and an increased risk of a blowout. I recommend making it a habit to check the tire pressure monthly with a gauge, keeping it at the manufacturer’s recommended value for peace of mind and safety. If the light keeps coming on repeatedly, it’s best to have it checked at a reputable shop instead of guessing blindly.
Speaking of the 10th-generation Accord's tire pressure warning light frequently coming on, my colleague's car had this issue and it took several attempts to fix it. The main reasons are: first, the tire pressure might be too low, possibly due to aging or air leakage; second, false alarms from the system. The Accord uses indirect monitoring via ABS to calculate tire pressure. If the tire pressure is unstable or the wear is uneven, it often causes errors. Try measuring the tire pressure and inflating it properly first, then drive for about 10 minutes to let it reset automatically. If it still doesn’t work, the sensor battery might be dead and needs replacement. Don’t underestimate this issue—low tire pressure increases handling risks on the road, and a blowout is no small matter. Pay attention to not overloading the vehicle, and measure tire pressure when the tires are cold for more accurate readings.
