Understanding Mazda TPMS Relearn
Mazda uses direct TPMS systems since the mid-2000s, meaning each wheel has a sensor transmitting pressure and temperature data. After replacing sensors—or rotating tires—the vehicle’s ECU must “relearn” each sensor’s unique ID and position. Skipping this step triggers the TPMS warning light and disables pressure readouts.
Three relearn methods exist for Mazda: auto relearn (hands-off), OBD relearn (quickest), and stationary relearn (manual). Your chosen method depends on available tools and vehicle year.
Mazda TPMS Relearn Methods
1. Auto Relearn (Drive Cycle)
Works on: Most Mazda models 2010 and newer.
- Inflate all tires to the pressure listed on your door placard.
- Drive above 25 mph for 10-15 minutes without stopping.
- The system learns sensor IDs in order: LF, RF, RR, LR.
- The TPMS light should turn off after a successful cycle.
Note: If the light remains on, try a full drive cycle (stop-and-go traffic) before attempting another method.
2. OBD Relearn (Tool Required)
Works on: All Mazda models with OBD-II (1996+), but most reliable for 2008+.
- Connect a TPMS programming tool (e.g., Autel, Bartec, or ATEQ).
- Select “Mazda” and the specific model/year.
- Trigger each sensor (LF, RF, RR, LR) using the tool’s activation function.
- The tool sends relearn commands via the OBD port.
- Verify the light turns off—typically within 30 seconds.
Tools Needed: Any OBD-compatible TPMS tool that supports Mazda protocols. Many aftermarket sensors, including the BL-ST-028 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Avatr, Changan, Deepal, Mazda, Nevo & 1 More | OE# 3601010CD01, 3601010DG01, 3601010MK02, are pre-programmed and only require this OBD step.
3. Stationary Relearn (Magnet Method)
Works on: Older Mazda models (2007-2012) and some Mazda3/Mazda6 variants.
- With the ignition on (engine off), locate the TPMS reset button (usually under the steering wheel or inside the fuse box area).
- Press and hold the reset button until the TPMS light blinks twice.
- At each wheel, hold a TPMS magnet near the valve stem for 5-10 seconds until the horn chirps.
- Follow the order: LF, RF, RR, LR.
- After the last wheel, turn the ignition off. The light should stay off on restart.
Important: This method requires a strong TPMS activation magnet—a regular fridge magnet rarely works.
Fitment Table: Compatible Mazda Models
| Model | Years | TPMS Frequency | Recommended Method |
|---|---|---|---|
| Mazda3 | 2007-2023 | 433MHz | Auto or OBD |
| Mazda6 | 2008-2023 | 433MHz | OBD (most reliable) |
| CX-5 | 2012-2023 | 433MHz | Auto (drive cycle) |
| CX-9 | 2007-2023 | 433MHz | OBD or Stationary |
| MX-5 Miata | 2006-2023 | 433MHz | OBD |
When to Use BL-ST-028 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Avatr, Changan, Deepal, Mazda, Nevo & 1 More | OE# 3601010CD01, 3601010DG01, 3601010MK02
The BH-Sens BL-ST-028 is a pre-programmed 433MHz clamp-in sensor that covers multiple Mazda OE numbers (3601010CD01, 3601010DG01, 3601010MK02). Since it’s pre-programmed, you simply install it and run a relearn—no cloning or manual programming needed. This saves 10-15 minutes per wheel compared to blank sensors.
Recommended Part: For Mazda owners replacing sensors, the BL-ST-028 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Avatr, Changan, Deepal, Mazda, Nevo & 1 More | OE# 3601010CD01, 3601010DG01, 3601010MK02 offers direct fitment without additional programming steps. Always verify the OE number on your existing sensor before ordering.
FAQ
How do I know if my Mazda needs a TPMS relearn?
If the TPMS warning light is solid (not flashing) after replacing sensors or rotating tires, a relearn is needed. Most Mazda models display the light for 3-5 seconds on startup if there’s a sensor ID mismatch.
Can I do a Mazda TPMS relearn without a tool?
Yes—auto relearn works on most 2010+ Mazda models by driving above 25 mph for 10-15 minutes. If that fails, you’ll need an OBD tool or magnet for stationary relearn.
Why is my TPMS light still on after the relearn?
Common causes: a sensor with low battery, incorrect tire pressure, or a sensor that isn’t transmitting (check for damage). If you’re using aftermarket sensors, ensure they’re 433MHz and compatible with your Mazda’s system.
Does the BL-ST-028 sensor work on all Mazda models?
It fits Mazda models listed in the fitment table above, but always cross-reference your OE part number (3601010CD01, 3601010DG01, or 3601010MK02) before purchasing. Some newer models (2024+) may use different frequencies.
