For 2016 Mazda 3 owners, understanding your vehicle’s systems is key to maintenance and performance. One powerful tool at your disposal is the On-Board Diagnostics II (OBD2) system. By using OBD2 PIDs (Parameter IDs), you can access a wealth of real-time data about your car’s operation, including the Tire Pressure Monitoring System (TPMS). This article will guide you through the essential OBD2 PIDs for monitoring your 2016 Mazda 3’s TPMS, ensuring you stay informed about your tire health.
Understanding OBD2 PIDs for Your 2016 Mazda 3
OBD2 PIDs are codes used to request data from your vehicle’s computer. For Mazda 3 models, including the 2016 version, accessing specific data like tire pressure and temperature requires using custom PIDs. This is because the standard OBD2 protocol doesn’t always provide manufacturer-specific information in a readily accessible format. Using the right PIDs and an OBD2 scanner, you can tap into this data, which is particularly useful for monitoring systems like TPMS that are crucial for safety and fuel efficiency.
Why Use Custom PIDs for TPMS on a 2016 Mazda 3?
The 2016 Mazda 3 utilizes an indirect TPMS system. While some vehicles directly measure tire pressure within each wheel, indirect systems often infer pressure changes based on wheel speed data from the ABS system. However, with custom OBD2 PIDs, you can often access more direct readings, or at least calculated values related to the TPMS, offering valuable insights beyond just a warning light. This is especially helpful for proactive maintenance and ensuring your tires are always at the optimal pressure.
Correct OBD2 PIDs for 2016 Mazda 3 TPMS
Below are the specific OBD2 PIDs for retrieving tire pressure and temperature data for your 2016 Mazda 3. These PIDs are designed to be used with OBD2 apps and scanners that allow custom PID input.
Tire Pressure PIDs:
| PID | Name | Short Name | Min | Max | Scale | Unit | Equation | Header |
|---|---|---|---|---|---|---|---|---|
| 222A05 | Tire 1 Pressure | T1Press | 0 | 50 | x1 | psi | ((A 1373) / 1000) 0.145037738 | 720 |
| 222A06 | Tire 2 Pressure | T2Press | 0 | 50 | x1 | psi | ((A 1373) / 1000) 0.145037738 | 720 |
| 222A07 | Tire 3 Pressure | T3Press | 0 | 50 | x1 | psi | ((A 1373) / 1000) 0.145037738 | 720 |
| 222A08 | Tire 4 Pressure | T4Press | 0 | 50 | x1 | psi | ((A 1373) / 1000) 0.145037738 | 720 |
Tire Temperature PIDs:
| PID | Name | Short Name | Min | Max | Scale | Unit | Equation | Header |
|---|---|---|---|---|---|---|---|---|
| 222A0A | Tire 1 Temp | T1Temp | -50 | 200 | x1 | F | (9/5 * (A – 50)) + 32 | 720 |
| 222A0B | Tire 2 Temp | T2Temp | -50 | 200 | x1 | F | (9/5 * (A – 50)) + 32 | 720 |
| 222A0C | Tire 3 Temp | T3Temp | -50 | 200 | x1 | F | (9/5 * (A – 50)) + 32 | 720 |
| 222A0D | Tire 4 Temp | T4Temp | -50 | 200 | x1 | F | (9/5 * (A – 50)) + 32 | 720 |

Note: These PIDs, Equations and Headers are crucial for accurate data retrieval. Ensure you input them correctly into your OBD2 app. ‘A’ in the equation refers to the raw value received from the OBD2 sensor.
Using These PIDs with OBD2 Apps
To utilize these PIDs, you’ll need an OBD2 adapter that is compatible with your 2016 Mazda 3 and an OBD2 app on your smartphone or tablet. Popular and effective apps include Torque (Android) and Car Scanner ELM OBD2 (iOS & Android), both of which allow you to add custom PIDs.
Steps to Add Custom PIDs (General Guide):
- Connect your OBD2 adapter to your Mazda 3’s OBD2 port, usually located under the dashboard on the driver’s side.
- Pair the adapter with your smartphone/tablet via Bluetooth or Wi-Fi, as per the adapter’s instructions.
- Open your OBD2 app and ensure it’s connected to the adapter and your vehicle.
- Navigate to the settings or menu option for managing custom PIDs or sensors. This might be labeled as “Add Custom PID,” “Custom Sensors,” or similar.
- For each PID you want to add (e.g., Tire 1 Pressure), input the values from the tables above: PID, Name, Short Name, Min, Max, Scale, Unit, Equation, and Header.
- Save the PID settings.
- Create a dashboard or display within the app to show the newly added TPMS PIDs.

Troubleshooting Tips
If you encounter issues reading data with these PIDs, consider the following:
- Incorrect PID Entry: Double-check that you’ve entered the PIDs, headers, and equations exactly as provided, paying close attention to case sensitivity and character accuracy.
- App Compatibility: Ensure your OBD2 app supports custom PIDs and is compatible with the ELM327 protocol, which is commonly used by OBD2 adapters.
- Adapter Issues: Test your OBD2 adapter with standard PIDs to ensure it’s functioning correctly and communicating with your Mazda 3’s ECU.
- Header and Equation Errors: Mistakes in the header or equation will prevent the app from correctly interpreting the data. Review them meticulously.
- EU vs. US Car Differences: While less likely, there’s a slight possibility that European models might have different ECU mappings. However, these PIDs are generally reported to work across different regions.
Monitoring your 2016 Mazda 3’s TPMS using OBD2 PIDs offers a deeper level of insight into your vehicle’s health. By correctly setting up these custom PIDs in your OBD2 app, you can regularly check your tire pressures and temperatures, contributing to safer driving and optimal vehicle performance.
