Why does my Suzuki Altos tire pressure light keep coming on, even after I check the tires?

The tire pressure warning light in my Suzuki Alto keeps coming on, even though I’ve checked and adjusted the tire pressure. What could be causing the light to stay on, and how do I resolve this issue?

If the tire pressure warning light keeps coming on despite checking your tires, there could be a few reasons:

Tire Pressure Monitoring System TPMS Issues: If the TPMS sensor is malfunctioning, it may incorrectly trigger the warning light. In some cases, the sensor may need to be recalibrated o r replaced.
Slow Leak: Even a small leak that you can’t detect by looking at the tire can cause the pressure to slowly, triggering the light. The tire may lose just enough air to activate the warning light but not be obvious to the eye.
Temperature Effects: As temperatures fluctuate, the tire pressure may slightly, which can trigger the warning light. Even if the tire looks fine, a minor pressure may be enough to activate the TPMS.
TPMS Calibration: If you’ve recently had the tires rotated o r replaced, the TPMS may need to be reset o r recalibrated to ensure accurate readings.
How to fix it:

Check for slow leaks: Inspect your tires for punctures o r cracks. If the light continues, take the vehicle to a professional mechanic to check for leaks.
Reset the TPMS: If the light comes on after tire rotation o r replacement, reset o r recalibrate the TPMS. This can often be done with a scan tool at a mechanic shop.
Inspect the TPMS sensors: If you suspect the TPMS sensors are malfunctioning, have them checked and replaced if necessary.
