To test the tire pressure sensors on a 2006 Highlander, use the Tire Pressure Monitoring System (TPMS) that relies on ABS wheel speed data. Inflate all tires to the recommended pressure on the tire placard. Turn the ignition to the ON position and reset the TPMS light with the reset switch under the dashboard.
To test the tire pressure sensors, remove the valve cap from each tire. Press the gauge onto the valve stem to obtain a pressure reading. Compare this reading with the recommended pressure. If the pressure is lower than specified, add air until it reaches the ideal level. After reinflation, reset the TPMS system by driving the vehicle above 50 mph for about 10 minutes. This process helps the sensors recalibrate and provide accurate readings.
If the TPMS warning light remains illuminated, the individual tire sensors might need testing or replacement. Understanding how to test tire pressure sensors ensures a more stable and safer ride.
