Why are some of my TPMS sensors not working?
A. Corrosion has been an issue with some original equipment TPMS sensors that have a nut at the base of the metal valve stem (snap-in style TPMS sensors with rubber valve stems are not subject to this type of corrosion). Exposure to road salt and moisture promotes galvanic corrosion that weakens the metal valve stem.
What do you need to know about Indirect TPMS?
Vehicles equipped with indirect TPMS do not have sensors in the wheels. Therefore, no sensor will be detected when trying to scan/activate/wake-up the sensors. Typically, the only service required is to inflate the tires to proper pressure and reset by pressing a reset button.
What do you need to know about Toyota TPMS?
Many Toyota and Lexus models have Set 1 and Set 2. All sensor positions for both sets need to be filled in the TPMS ECU. On Toyota and Lexus vehicles, the system will be locked if a sensor is replaced and the tire rotation button is pushed. ATEQ and Bartec tools can clear this lock.

Is there a way to repair your TPMS sensor?
The reCore®, a patented system, is now be available for the first time for consumers to repair their own damaged sensors. This DIY kit allows the repair of corroded aluminum TPMS valve stems right on the vehicle without having to remove the tire or wheel.

Many Toyota and Lexus models have Set 1 and Set 2. All sensor positions for both sets need to be filled in the TPMS ECU. On Toyota and Lexus vehicles, the system will be locked if a sensor is replaced and the tire rotation button is pushed. ATEQ and Bartec tools can clear this lock.
