Exploring the capabilities of a Bluetooth OBD2 scan tool, the BlueDriver, on a 2007 Honda CRV reveals interesting live data for vehicle diagnostics. This well-regarded scanner, known for its enhanced Honda vehicle support, offers users the ability to monitor real-time performance metrics. While no fault codes have emerged on this new Honda CRV – a positive sign for reliability – the live data stream provides valuable insights into the engine’s operational characteristics.
One notable observation is the engine coolant temperature. Engine Coolant Temperature 1 (ECT1) readings suggest that the 2007 Honda CRV engine operates consistently between 80°C and 85°C (176°F to 185°F). This temperature range appears slightly cooler compared to some other engines. Regardless of driving conditions, from stop-and-go traffic to extended idling, this temperature range remains stable once the engine reaches its operating temperature. The dashboard temperature gauge begins to move at approximately 55°C (132°F) and reaches its maximum indicated position around 75°C (165°F). The data indicates that the thermostat likely opens when the engine reaches its normal operating temperature, evidenced by the Engine Coolant Temperature 2 (ECT2), representing radiator coolant temperature, starting to increase at this point.

Fuel trim analysis via the BlueDriver scanner shows consistently negative values. Short Term Fuel Trim (STFT) averages around -5.5%, and Long Term Fuel Trim (LTFT) is approximately -8%. Initial readings were taken using E0 fuel, and a switch to E10 fuel is being tested to observe any potential positive shift in these fuel trim values, as suggested by some users.
The BlueDriver’s live data display is user-friendly, presenting numerical readings and allowing for graphical representations of the data. Visualizing data trends over time enhances the diagnostic process. For instance, graphs can be created to track all collected live data or to zoom in specifically on parameters like STFT and LTFT for detailed fuel system monitoring.

Monitoring these parameters through seasonal changes, particularly in colder winter conditions, will provide further insights into the 2007 Honda CRV’s engine behavior. For owners in regions with cold winters or those frequently engaging in short-distance commutes, tools like the BlueDriver OBDII scanner offer valuable data for understanding and maintaining their vehicle’s performance.
