Step-by-step directions on Toyota TPMS changing

TPMS is mandated in vehicles after 2008 in the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act. It is shorted for Tire Pressure Monitoring System and is a sensor that can often be found in the tire’s valve stem. This device measures tire pressure and temperature, and transmits this data to your tire pressure monitor ECU/receiver. But sensors can be faulty because of many reasons ranging from mechanical to electrical problems. If you try to change your TPMS-quipped tire, pay attention to the sensors and avoid damage.
Things You’ll Need
Replacement TPMS
Bartec Wheelrite TECH400 tool
Support stands
Penetrating oil
Tire iron
1. Take your car to a certified technician, who will use a Bartec Wheelrite TECH400 tool to determine if your sensor needs replaced, and also pinpointing the nature of the problem.
2. Buy a replacement sensor-containing valve stem that is configured for your Toyota. To cut down on costs, try purchasing a replacement sensor from aftermarket sources.
3. Raise your car in the air using a jack and support stands. Remove your tire by spraying its lug nuts down with penetrating oil then using a tire iron to remove the nuts.
4. Relieve the tire pressure by unscrewing the valve stem cap to let air out. The valve stem is a metallic valve that sticks out from the tire. Next, lay the tire on the ground and use a crowbar to break the beads, or seal between the wheel and tire. Pry the tire from the wheel with the crowbar.
5. Soak and lubricate your replacement valve stem in some liquid dish soap, then slide it into the hole in the tire vacated by the old valve stem. The valve will seal itself. Seat the tire beads onto the wheel using the crowbar.
6. Reinflate the tire according to the manufacturer’s specifications, which can be found in the owner’s manual.
7. Reprogram the ECU (Engine Control Unit) with the diagnostic tool using the replacement TPMS’s unique ID and its position on your car. This information varies from model to model, but can found the sensor’s service manual. The ECU is generally found on the engine, though its exact location varies from model to model.
