Are There Multiple Types of Tire-Pressure Monitoring Systems?

Since the beginning of the 1990s, when specific luxury vehicles first appeared with Tire-Pressure Monitoring Systems (TPMS), two types of systems have existed. Your TPMS may be either a Direct type of TPMS or Indirect. For driving around Red Deer, the kind of system your vehicle uses is not an issue. Out on the highway, however, the type of TPMS could make a significant difference.

A Direct TPMS uses physical sensors to monitor the air pressure inside each tire on your vehicle and continuously relay that information to your central information cluster. If a loss in pressure is detected, the driver is informed via a dash indicator—usually an indicator light. Indirect TPMS measures the rotational speed of each tire and compares that information to the other tires. When a difference is detected, the driver is warned via the dash light.

If your TPMS indicates a low-pressure in a tire, come to Southside Dodge Chrysler.
