How to Eliminate Tire Pressure System Malfunction?
2 Answers
Tire pressure system malfunction elimination methods are: 1. Turn off the engine, wait for 1 to 2 minutes, then restart the vehicle; 2. Inflate or deflate the tire pressure and observe the tire pressure light display on the vehicle dashboard; 3. Locate the settings button on the car's central console dashboard to reset the tire pressure; 4. Use a specialized diagnostic tool to clear the fault code. Reasons for the tire pressure monitoring light to illuminate: 1. Punctured tire: This situation usually involves very slow air leakage. Use a tire pressure gauge to measure and observe the tire pressure. If the light comes on again after a few days, inspect the tire by removing it; 2. Excessive tire pressure: According to international standards, the recommended inflation pressure for passenger car tires is: standard tires: 2.4 to 2.5 bar. When the tire pressure exceeds 3.0 bar, the tire pressure monitoring light will trigger; 3. Driving with low tire pressure for too long: This usually occurs when a tire's pressure is too low, causing the tire temperature to rise during high-speed operation. In such cases, stop and rest promptly or replace the spare tire; 4. Long-term lack of tire inflation leading to low pressure: When the pressure falls below 1.5 bar, the tire pressure monitoring light will illuminate. Regular checks should be performed to ensure the tire pressure monitor is functioning normally.
When the tire pressure monitoring system (TPMS) warning light illuminates, the most direct solution is to manually check each tire's actual pressure using a tire pressure gauge to see if it's below the standard value. If the pressure is low, inflate the tires to the manufacturer's recommended range as soon as possible—typically around 30-35 PSI for passenger cars. After inflation, locate the vehicle's reset button or perform a system reset through the dashboard menu, as the system needs to recalibrate the pressure data to clear the fault code. If the light remains on after resetting, it may indicate a depleted or damaged sensor battery. In this case, purchasing a new sensor for replacement or using an OBD tool to diagnose the specific issue would be effective. Prevention is also crucial: check tire pressure monthly, as cold weather can cause pressure drops, and preemptively inflate to avoid false alarms. For safety, never ignore this issue while driving, as unstable tire pressure can lead to blowouts or compromised handling.
