American Honda gives a big thumbs down on the usage of aftermarket tire puncture sealants in vehicles with TPMS. Although these products are a blessing in a roadside emergency, they're bad news for TPMS sensors. Tire puncture sealant plugs up the port that measures the tire pressure, making the sensor useless.
If you get a vehicle in your shop for tire repair and your service client inflated the tire with a tire puncture sealant, you've got to thoroughly clean out all of the sealant and replace the TPMS sensor as part of your repair.
