How do you know if TPMS is direct or indirect?

Direct TPMS systems use TPMS sensors inside the wheel to report pressure data to the vehicle’s ECU in real time. The direct systems include Asian, domestic and European vehicles. An indirect TPMS system uses an ABS system to monitor the speed of the wheel in order to record tire pressure readings correctly.

In this manner, what is indirect tire pressure monitoring system?

Indirect Tire Pressure Monitoring Systems (TPMS) are the systems that do not have air pressure sensors inside the tires. Rather, they detect a low tire by comparing relative wheel speeds via the Anti-lock Brake System (ABS) wheel speed sensors. When a tire loses air, its diameter decreases slightly.

Also Know, how does a direct tire pressure sensor work? Direct TPMS uses a sensor mounted in the wheel to measure air pressure in each tire. When air pressure drops 25% below the manufacturer’s recommended level, the sensor transmits that information to your car’s computer system and triggers your dashboard indicator light.

Subsequently, question is, how do I know if my car has TPMS?

To confirm if your vehicle has TPMS, turn the key to the “On” position without starting the engine. If you see a light on your dashboard that looks like the one below, you have TPMS. You can also check the owners manual for your vehicle for more information.

Where is TPMS sensor located?

The tire pressure sensor is located inside a tire where it is attached to the inner part of the rim. You can easily find it once you remove the tire from the rim.
