Does Subaru use direct or indirect TPMS?
Subaru primarily uses indirect TPMS in many models, but some newer trims and markets employ direct TPMS with wheel-mounted sensors. The exact system depends on model year and region, so check your owner’s manual or confirm with a Subaru dealer for your specific vehicle.
Understanding TPMS types
Below is a concise breakdown of how direct and indirect TPMS differ in practice on Subaru vehicles.
- Direct TPMS: Each wheel has a pressure sensor that reports actual tire pressure to the vehicle’s computer. This provides specific pressure readings and individual tire warnings. Maintenance can include sensor replacement or reprogramming when tires are changed, and sensors have a finite battery life.
- Indirect TPMS: No tire-mounted sensors exist. The system uses ABS/ESP wheel-speed data and tire size to infer underinflation and triggers a general warning. Calibration may be needed after tire changes or when replacing tires with a different size. It does not provide exact pressures without a gauge.
Direct TPMS offers precise readings and can be more reliable in some conditions, while indirect TPMS is cheaper to implement and avoids sensor maintenance but relies on other systems for inference.
How to determine which TPMS your Subaru has
To identify the TPMS type for your specific Subaru, use these steps. The exact answer can vary by model year and market.
- Check the owner's manual or Subaru’s official specifications for your model/year for explicit TPMS wording (direct vs indirect).
- Inspect the wheels and valve stems: direct TPMS vehicles typically have metal valve stems with wheel-mounted sensors; indirect TPMS cars may use standard valve stems without sensors visible at the rim.
- Observe the TPMS warning behavior: direct TPMS can display individual tire pressures or a specific tire warning; indirect TPMS usually shows a general warning about underinflation.
- Ask a Subaru dealer or use your VIN to pull the exact TPMS configuration from official service data.
Knowing the TPMS type helps with tire maintenance, sensor replacement timing, and proper calibration after tire work.
Maintenance implications and what to expect
Understanding the TPMS type informs how you maintain tires, rotate wheels, and service sensors. Consider these points when planning tire work.
- Direct TPMS: You may need to service or replace wheel sensors during tire changes; ensure proper sensor programming and account for sensor battery life.
- Indirect TPMS: Recalibration may be required after installing new tires or changing wheel sizes; always verify actual tire pressures with a gauge in addition to the warning light.
In all cases, Subaru recommends regular tire pressure checks and maintenance to ensure safety, fuel efficiency, and optimal handling.
Summary
Subaru uses indirect TPMS on many models, with direct TPMS appearing on newer trims or in certain markets. To know which system your vehicle has, consult the owner's manual, check dash indicators, inspect valve stems, or contact a Subaru dealer using your VIN. Regular tire pressure checks remain essential regardless of the TPMS type.
Which manufacturers use indirect TPMS?

- Mercedes SLK 2005-'07.
How to tell if your car has direct or indirect TPMS?
Direct TPMS sensors are located within the tyre, usually in the space between the tyre and the wheel trim. As indirect TPMSs use the sensor on the anti-lock braking system (ABS), this sensor is typically located near the brake rotor.
What kind of TPMS sensor does Subaru use?
A TPMS from Schrader Electronics is fitted as part of the valve assembly in all Subaru cars according to the table shown below.
Is the Subaru TPMS direct or indirect?
After the TREAD Act was mandated in 2007, all vehicles manufactured in the United States beginning in 2008, must be installed with direct or indirect TPMS systems. The Subaru Crosstrek is manufactured with a direct TPMS system, which means TPMS sensors are installed in the wheel.
