Resetting the tire pressure monitoring system on a 2018 Toyota 4Runner is a fairly simple task. Start by confirming that the tire pressure is correct, which should be at 32 psi for both the front and rear tires. Once that is done, turn on the engine and locate the reset button on the instrument panel, positioned to the right and below the steering wheel. Press and hold the reset button until the TPMS indicator light blinks three times slowly. Wait a few minutes for the system to check the pressure, then switch the engine off and on again to verify that the reset was successful.
The 2018 Toyota 4Runner lacks a built-in feature to reset the Tire Pressure Monitoring System (TPMS) automatically as it should. Following a TPMS replacement, an issue arose where no errors were initially displayed, but the power pressure fault warning would start blinking after some time - indicating a system error rather than a pressure fault. Eventually, the warning became solid. To resolve this, it was necessary to have a specialist at a Toyota dealership program the new TPMS IDs into the car's computer via a manual process, effectively addressing and resolving the issue.
To reinitialize the tire pressure monitoring system (TPMS) on a 2018 Toyota 4Runner, first ensure that the tire pressure is accurate. Next, start the car and press the reset button located to the right of the steering wheel. Wait for ten minutes. If necessary, continue holding down the button until the light flashes. Incorrect tire pressure can lead to the sensor malfunctioning and affect the vehicle's performance negatively.
