This week, get some tips on how to read or activate a TPMS sensor, and what to do if you are having trouble reading a sensor.
Tip #1: Check to make sure that this vehicle has a direct-TPMS system. This can be easily checked using a VT55 or VT56 TPMS tool, where it shows under the service menu if the specific vehicle you’ve chosen is an indirect system. An indirect TPMS system does not have sensors in the tire, instead, it communicates through the ABS system to calculate the tire pressure of each tire, therefore, no sensors can be read.
Tip #2: Make sure you are holding your tool properly to the tire for an accurate reading. When reading a sensor, make sure to read it at the sidewall of the tire. The sensor is read and activates with low radio frequency so there could be interference if reading sensors from the wrong position. Some aftermarket rims can affect tire readings.
Tip #3: What is the condition of the sensor? If you are unable to read a sensor, the sensor battery could be dead or corroded, so it is important to visually inspect the sensor outside of the wheel.
Tip #4: Have you updated your TPMS tool? If you are unable to read the sensor, you may need to update your TPMS tool. The latest TPMS software will include the latest vehicle and TPMS sensor coverage, so be sure to perform a TPMS update. Check your tool under the SETTINGS menu for the latest software update and compare it to the latest update notes online.
