There are key opportunities to streamline service and prevent future TPMS-related comebacks.
Tire pressure monitoring systems (TPMS) are standard on modern vehicles, but many technicians still miss key opportunities to streamline service and prevent future comebacks when it comes to TPMS sensor replacement. Here are a few quick tips to stay ahead.
TPMS Sensor Replacement When Replacing Tires
When it comes to TPMS sensor replacement, if one sensor shows a low battery, chances are the others are close behind. Customers will appreciate the long-term value, and you avoid return visits when the next sensor inevitably fails.
Know the Difference Between Direct and Indirect TPMS
Direct TPMS uses individual sensors in each wheel to transmit real-time pressure readings. Indirect systems estimate pressure using ABS data and wheel speed calculations. That distinction matters when diagnosing faults or interpreting warnings.
How Sensors ‘Wake Up’
TPMS sensors don’t transmit constantly. Movement – sensed by an internal accelerometer – wakes them up. So does rapid deflation or a TPMS scan tool emitting a 125 Hz signal.
Update TPMS Tools Regularly for Quick TPMS Sensor Replacement
Don’t waste time waiting for a download. Check monthly so you’re ready when newer vehicles hit your bay.
Understand Sensor Modes
Sensors switch between drive, alert, and sleep modes depending on movement or pressure change. Some even ship in “shipping mode” and must be activated with a tool. Knowing the mode ensures faster troubleshooting.
