Why does the tire pressure monitoring light of the Civic keep coming on?
2 Answers
Civic's warning light may stay on due to an improper air-fuel mixture ratio or insufficient combustion in the engine cylinders, leading to an overly rich fuel system. It is recommended to visit an auto repair shop to check the oxygen sensor, replace the fuel injectors, and clean the throttle body. Civic specifications: Fuel consumption: 5.0-6.4L, Body structure: 4-door 5-seater sedan, Engine: 1.0T/1.5T, Transmission: 6-speed manual/CVT, Drivetrain: Front-wheel drive, Fuel type: Gasoline. Tire pressure monitoring light: The tire pressure monitoring indicator is a yellow symbol—an irregular circle without a seal at the top, with four small spikes at the bottom and an exclamation mark inside. The light indicates abnormal tire pressure. Abnormal tire pressure is generally caused by one of the following three reasons: Abnormal tire pressure: Usually, the system will alert if the pressure is below 1.8 bar or above 3.0 bar. In this case, the tires need to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure monitoring system is not reset in time, it will still record the previous data, causing the tire pressure monitoring light to stay on. Simply reset the tire pressure monitoring system to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged due to impact while driving, the tire pressure warning light will illuminate. In case of sensor damage, the only solution is to replace it with a new one.
I drive a Civic, and the tire pressure warning light keeps coming on, which is really annoying. Most of the time, it's due to a slow leak from a punctured tire or a small nail, causing the pressure to drop below the set value. Cold weather can also lower tire pressure, making the light more likely to come on. The Civic's system is quite sensitive—if temperature fluctuations cause unstable tire pressure, it will trigger an alert. Before checking the tires, use a tire pressure gauge to measure each wheel. The standard values are listed on the label by the door, usually between 32-35 PSI. If the pressure is normal but the light remains on, the sensor might be faulty or the battery dead. Civic's TPMS sensors typically last five to six years, and replacing them can solve the issue. Try inflating the tires with a pump—if the light goes off, you're good. Otherwise, it's best to visit a repair shop for a thorough check to avoid bigger problems down the line.
