Direct vs Indirect TPMS
There are two main types of TPMS systems used in modern vehicles: direct TPMS and indirect TPMS. Understanding the difference helps you know how your system works, why your warning light may come on, and what kind of diagnosis or repair may be needed.
What is Direct TPMS?
Direct TPMS uses sensors inside each wheel to measure tyre pressure in real time.
Advantages
- Accurate pressure readings
- Quick fault detection
- Identifies which tyre has the issue
Common faults
- Sensor battery failure
- Damaged sensors
- Requires programming
What is Indirect TPMS?
Indirect TPMS uses ABS sensors to detect tyre pressure changes instead of physical sensors.
Advantages
- No sensors to replace
- Lower cost
Limitations
- Less accurate
- No pressure readings
- Needs manual reset
Which is better?
Direct TPMS is more accurate and used in most modern vehicles, but requires proper diagnostics when faults occur.
If your TPMS light stays on, it may be a sensor issue rather than low pressure.
Need TPMS Help?
If your warning light is on or you think you may have a faulty sensor, get in touch for diagnostics, sensor replacement or programming.
