What are the causes of Buick Regal's tire pressure monitoring system malfunction?

In fact, such issues are usually caused by electromagnetic interference. It is estimated that the tire pressure reception frequency of General Motors is close to the frequency of self-installed electronic equipment, leading to this problem. Below is the relevant introduction: 1. Introduction to the tire pressure monitoring system: TPM-IS is a tire pressure detection initialization system specially designed for vehicle manufacturers. It uses radio frequency technology to quickly activate, identify, and locate various TPMS sensors, and writes relevant information into the vehicle's ECU electronic control unit through the OBDII interface, ultimately realizing the initialization of the tire pressure detection system. 2. Structure: TPM-IS consists of a line-side industrial computer, barcode scanner, vehicle positioning and identification device, LF wake-up module, RF receiving module, printing equipment, alarm equipment, etc.
Last time I took my car for repair, the mechanic said the most common issue with the Buick Regal's tire pressure monitoring is the sensor running out of battery. The built-in battery usually lasts only five or six years, so older cars are particularly prone to this. Also, many sensors get damaged during tire repairs or replacements due to improper handling by workers. Another issue is corrosion or damage to the wiring under the car, which prevents the signal from transmitting. My neighbor's car had an even weirder problem—a strong magnetic phone mount actually interfered with the tire pressure signal, and removing it fixed the issue. Driving on rough, bumpy roads can also loosen the sensor connections. It's recommended to first check if the actual tire pressure is normal. If it is, then quickly take it to a professional shop to read the fault codes. Trying to fix it yourself might make things worse.
