What to Do When the Tire Pressure Monitoring System Shows Left and Right Reversed?
2 Answers
The solutions for when the tire pressure monitoring system shows left and right reversed are: 1. Re-adjust the tire pressure sensors by reinstalling them in their correct left and right positions; 2. If the owner does not want to reinstall them, the tire pressure can be rematched. The tire pressure monitoring system automatically monitors the tire pressure in real-time while the car is in motion and alerts the driver to tire leaks or low pressure to ensure driving safety. The working principle of the tire pressure monitoring system is that a built-in sensor is installed on the tire hub. The sensor includes a bridge-type electronic pressure sensing device that detects air pressure, converts the pressure signal into an electrical signal, and transmits the signal via a wireless transmitter.
I've been driving for over 20 years and have encountered the issue of reversed tire pressure monitoring several times. Usually, it happens when technicians accidentally install the sensors in wrong positions during tire replacement. Here's what I did: First, don't panic. Use a tire pressure gauge to manually check each tire's actual pressure to ensure safe driving conditions. If the actual pressures are correct but the display is reversed, then a position relearn procedure is needed. Most vehicles have a reset function - for example, my car can follow the manual's procedure to automatically correct the positions during driving. If that doesn't work, use an OBD tool or visit a repair shop. While not a major issue, it shouldn't be ignored because reversed monitoring may trigger false alarms (e.g., showing right tire warning when left tire is leaking), potentially creating accident risks. During routine maintenance, I always remind technicians to clearly mark tire positions to avoid repeated issues and reduce hassle.
