Schrader TPMS (EZ Sensor)
Dill TPMS (Redi Sensor and OEM)
What is TPMS?
TPMS stands for Tire Pressure Monitoring System. An electronic system that alerts a driver of either a low-pressure issue or system malfunction. System malfunctions can be catastrophic pressure changes through sensors failing. Usually the warning shows up on the dash of the vehicle as an icon, warning message or both.
Readings are provided by pressure sensing transmitters mounted on the inside of each tire and sent to a central computer (ECU) for display on the dashboard. Direct TPMS enables simultaneous detection of under inflation in any or all of the four tires.
McGee Company offers a variety of TPMS products from OEM to aftermarket. Our key vendors are Schrader and Dill for sensors themselves and the Bartec programming tool for diagnosis of issues and programming sensors.

TPMS sensors come in two main categories; direct and indirect. The indirect system calculates wheel speed based on the anti-lock brake system (ABS). Under inflated tires have a smaller radius and therefore a higher rotational speed, however, “this change in radius is small, making indirect measurement less reliable” (Safer Car, 2014). Direct TPMS systems are sensors in the valve stem and transmit data from each individual sensor to the car’s receiver. When there is low pressure, there is a warning light that appears on the car’s dash. Through constantly checking tire pressure, the tire temperature, and sensor identification/battery life, TPMS sensors increase fuel efficiency, improve handling, and reduce braking time. The U.S. government mandated all cars manufactured post 2008 be equipped with TPMS sensors and started a partial percentage based integration in 2006.
