Finding a Fix: Troubleshooting Customer TPMS Problems Cheshire CT
Low profile tires with short, stiff sidewalls change diameter less than tires with tall aspect ratios that have more compliant sidewalls. Consequently, a loss of 10 psi in a low profile tire may only change the diameter of the tire less than 1mm (0.040 inches). Most ABS-based systems cannot detect changes smaller than 1 mm. For this reason, indirect ABS-based TPMS systems are not as sensitive as the newer direct systems which have a pressure sensor inside each wheel.

The history of how we got to this point with TPMS is not important. It’s here, and tire dealers have learned to deal with it. The next question deals with how we learn to troubleshoot TPMS for our customers, who at this point know virtually nothing about it.
The early version of TPMS, the indirect system, was first used on 1999 to 2003 model year OE applications. There were TPMS trial applications dating back to the late 1980s, but they clearly needed more work. OEMs abandoned those early systems in favor of the more reliable indirect system, and ultimately the direct systems that are most prevalent today.
Because you are still servicing both systems, we’ll start with the indirect system since there are so many vehicles out there equipped with this version. First, it’s an ABS-based system. If a tire loses air, the diameter of the tire shrinks slightly, causing it to rotate at a slightly faster rate than the other three tires.
But on most applications a tire has to lose anywhere from 8 to 14 pounds of air pressure before there’s enough of a difference in overall diameter to be detected by the wheel speed sensors. This depends on the type of tire, the tire’s diameter, aspect ratios and the sensitivity of the ABS system. They sure didn’t make it easy to troubleshoot did they?
