Choosing the best Bluetooth professional OBDII scan tool in the $150 to $200 price range can be challenging. This article explores the use of the OBDLink MX+ and the OBDLINK app with the Toyota-specific package for monitoring transmission temperatures, addressing concerns about accuracy and providing insights into real-world experiences.
Decoding Transmission Temperature Readings with OBDLink MX+
When using the OBDLink MX+ with the Toyota package on a Toyota vehicle, the app displays multiple readings for transmission oil temperature. One user reported unusual readings for “A/T Oil Temperature 3,” showing temperatures significantly below ambient, even in a relatively warm garage. While “A/T Oil Temperature 1” seemed plausible, the discrepancy raised concerns about the overall accuracy of the data.
OBDLink’s Response and Further Investigation
Upon contacting OBDLink technical support, the user was informed that the Toyota data used in the app was sourced directly from North American Toyota. However, support could not explain the anomalous “A/T Oil Temperature 3” readings. They suggested potential variations in calculation methods between different vehicle models and ECUs, recommending further testing to confirm the accuracy of “A/T Oil Temperature 1.” This response, while acknowledging the issue, offered limited practical assistance.
The experience highlights the importance of verifying data from OBDII scan tools, especially when dealing with critical parameters like transmission temperature. While the OBDLink MX+ generally receives positive reviews, this case underscores the potential for discrepancies in manufacturer-provided data and the need for user-level validation. Further research and testing are recommended to determine the most reliable transmission temperature reading within the OBDLINK app for specific Toyota models. This could involve comparing readings against other known-good temperature sources, such as an infrared thermometer. Users in the $150 to $200 price range seeking a reliable Bluetooth OBDII scanner should consider factors like data accuracy, software support, and user reviews when making their decision. Finding a tool with accurate and consistent data is paramount for effective vehicle diagnostics and maintenance.
