A recent experiment tested the compatibility of an Autel TS508 TPMS tool with various 2023 Toyota models. The goal was to determine if the Autel sensor could successfully read tire pressure data from different Toyota vehicles, specifically focusing on potential changes in sensor protocols for the 2024 and 2025 model years. While access to 2024 and 2025 models was unavailable, a 2023 Toyota Sienna, Camry, and Grand Highlander were tested.
The Autel TS508 successfully read the TPMS data from the 2023 Sienna using the pre-programmed setting: Toyota Sienna 01/2021-12/2024 (315 MHz) with OE Sensor Information = 42607-0E030. The tool returned a sensor ID of 9E051DB, pressure of 32.3 psi, and temperature of 46°F within seconds.
However, using the settings for a 2020-2024 Camry (315 MHz Snap in) with OE Sensor Information = 42607-02050 / PMV-E000 and a 2023-2024 Grand Highlander (315 MHz E000) with OE Sensor Information = 42607-0E090 / PMV-E000 resulted in trigger failures and timeouts. The Autel TS508 could not capture sensor transmissions from either vehicle using these settings.
These findings suggest a few key takeaways regarding Autel sensor compatibility with Toyota vehicles:
- Unique Sienna TPMS Code: The 2023 Sienna appears to utilize a unique TPMS code distinct from other Toyota models, at least within the scope of this test. The Autel TS508, using the Sienna-specific setting, could not read data from the Camry or Grand Highlander.
- Toyota’s Complex TPMS Landscape: Toyota’s TPMS system presents a challenge for compatibility. Both the Camry and Grand Highlander reference the Pacific E000 sensor, yet use different Toyota part numbers. This suggests potential variations within the E000 sensor family that might impact TPMS tool compatibility. Further investigation into the nuances of the E000 sensor and its variations across Toyota models is needed.
- Further Testing Required: This limited test did not include vehicles equipped with the C015 sensor or any 2024 or 2025 models. Additional testing is necessary to determine if the observed incompatibility is specific to the 2023 model year or indicative of broader changes in Toyota’s TPMS technology.
This preliminary investigation highlights potential challenges in using Autel TPMS tools with newer Toyota vehicles. Further research and comprehensive testing across a wider range of Toyota models and model years, including analysis of the Pacific E000 sensor variations, are crucial for confirming these findings and ensuring accurate TPMS service and repair. Whether this incompatibility stems from vehicle-specific changes or inaccuracies in TPMS tool data tables remains to be seen.
