Most TPMS issues are preventable with a little extra attention to the details.
With the right TPMS service tips and a little extra attention to detail, the difference between a smooth job and a comeback is usually just a matter of awareness.
TPMS Service Tips: Check the Valve Stem
If a vehicle comes into your shop with wheel or tire damage from hitting a curb or pothole, it’s easy to focus only on those obvious issues. But technicians should also take a close look at the valve stem, especially on TPMS sensors that use a clamp-in style. The same impact that damaged the wheel could have weakened the valve stem, so it may need to be replaced.
While you’re at it, grab your scan tool and run a quick check on all sensors. If the vehicle has older or weaker sensors, it may be time to replace more than one, or all of them. If one TPMS battery is dead, the others likely aren’t far behind. Replacing them together can save the customer a return visit and save your shop the time of repeating the process later.
Test Communication Before Installation
Putting new sensors in comes with its own set of risks. Without verifying communication beforehand, you may find yourself stuck with no signal and no easy fix.
That’s why you should always use your scan tool to confirm communication before installation. That extra step ensures the sensor is active and functional before the vehicle leaves the bay. Skipping it can cause delays and frustration from both your techs and customers. There’s nothing worse than handing the keys back only for the customer to see a TPMS light pop up again soon after.
Be Careful with Equipment
Modern tire changers, especially center-post styles designed for low-profile tires or large-diameter rims, can be a big help. But they also create new opportunities for unintentional TPMS damage. Even when no tire iron is involved, the positioning of the equipment itself can put sensors at risk.
That’s why it’s important to know exactly where the TPMS sensor is before working with one of these machines. Pay close attention to where your tools and implements are in relation to the sensor. A quick moment of awareness can prevent costly damage that otherwise might not be noticed until it’s too late.
Take TPMS Service Seriously
Remember, TPMS service is about more than just clearing a dashboard light and getting your customers on their way. Pay attention to valve stem condition, confirm communication with your scan tool, and keep sensor location in mind. These steps may seem small, but each will help your shop prevent bigger problems later.
Taking TPMS seriously protects customer safety and your shop’s reputation.
