How to Reset Tire Pressure Monitoring in a 4Runner

by Alibaster Smith

The tire pressure monitor in your 4Runner monitors the tire pressure via a small sensor in the tire's valve stem. If the pressure gets too low in any tire, the tire pressure monitor will send a signal to the 4Runner's dash panel and illuminate the monitor warning light. In order to shut off and reset the tire pressure monitor light, you need to make sure that the tire pressure is correct. The correct tire pressure for your 4Runner is printed on the sidewall of your 4Runner's tires under "MAX PSI." The correct tire pressure is also printed on the driver's side door jamb.

Step 1

Turn on the air compressor and connect the tire pressure gauge to the air compressor hose using the quick-connect lock on the end of the air compressor's hose.

Step 2

Unscrew the valve stem cap on your 4Runner's tires.

Step 3

Press the tire pressure gauge over the end of the valve stem and fill the tire with air until the gauge reads the maximum pounds per square inch that the tire will accept.

Step 4

Screw the valve stem cap back onto the end of the valve stem.

Step 5

Turn the ignition key to the "On," or second, position on the ignition, but do not crank the engine. Press and hold the reset button on the instrument panel until the TPMS light starts blinking and then goes out. This is a "hard reset" that you can do if the TPMS light does not go out after inflating the tires to the proper pressure.
