What is the TPMS fault in Geely Emgrand?
3 Answers
Geely Emgrand TPMS light indicates the tire pressure monitoring system warning light, signaling a tire pressure fault, deviation from normal values, or foreign object penetration in the tire. Dimensions: The Geely Emgrand measures 4632mm in length, 1789mm in width, and 1470mm in height, with a wheelbase of 2650mm. It is equipped with a 5-speed manual transmission and has a top speed of 175 km/h. Configuration: The Geely Emgrand features front-wheel drive, with MacPherson independent front suspension and torsion beam non-independent rear suspension. It comes with brake force distribution, tire pressure monitoring, driver seat belt reminder, child seat interface, and keyless remote start system.
When the TPMS warning light comes on in my Geely Emgrand, my first reaction is to check the tires. This system essentially monitors tire pressure - the light may simply indicate a punctured tire losing air, which can be identified using a tire pressure gauge. If the tire pressure is normal but the light remains on, it's most likely a sensor issue - I've encountered this before where the sensor battery dies after 5-6 years of use, and replacement costs a few hundred yuan. Signal interference is another possibility, such as from aftermarket electronic devices disrupting sensor signals. The safest approach is to visit a 4S dealership to scan for trouble codes, which can precisely identify which wheel's sensor has failed.
Last time on the highway, my Emgrand TPMS suddenly alarmed, which made me quite nervous. I immediately pulled over to check the tires, but all four tire pressures were normal. Later, the mechanic said it was a false alarm from the tire pressure monitoring system, with three common causes: either the sensor battery is depleted (especially for cars over 6 years old, it's almost inevitable), or the sensor was damaged by high-pressure car wash water jets, or the module wiring got damp and short-circuited. He advised against trying to fix it myself, as professional equipment can diagnose whether it's a sensor or receiver issue in just a minute, and then simply replace the faulty part.
