Lexus LS460 low air pressure lamp remains on after inflating tires to 34 PSI due to cold weather on Lexus LS460

Some Lexus LS460 owners report experiencing issues with the low air pressure lamp remaining on even after inflating their tires to 34 PSI due to cold weather. These concerns can arise from temperature variations that cause tire pressure to drop, triggering the warning light. Additionally, some owners find that the Tire Pressure Monitoring System (TPMS) may need to be reset or recalibrated after tire inflation, as failure to do so can keep the low air pressure lamp illuminated. Another factor to consider is the pressure of the spare tire, which, if low, can also activate the TPMS warning light. Furthermore, persistent issues may indicate a malfunction in one of the tire pressure sensors, leading to inaccurate readings. To address these problems, it is advised to check the spare tire pressure, reset the TPMS, inspect the sensors for malfunctions, and monitor tire pressure as temperatures fluctuate.
