7. How to Interpret OBD2 Data on Your iPhone

Interpreting OBD2 data requires some understanding of the various parameters and codes. Here are some key areas to focus on:

• Diagnostic Trouble Codes (DTCs): These are codes that indicate a specific problem with your car. OBD2 apps will usually provide a description of the code, but you may need to do further research to understand the root cause and how to fix it. Resources like the National Highway Traffic Safety Administration (NHTSA) website can be helpful in understanding DTCs.
• Real-Time Sensor Data: This includes data from various sensors in your car, such as engine coolant temperature, oxygen sensor readings, and mass airflow. Monitoring these parameters can help you identify potential problems before they trigger a DTC.
• Freeze Frame Data: This is a snapshot of the sensor data at the moment a DTC was triggered. It can provide valuable clues about the conditions that led to the problem.

Example of DTC Interpretation

DTC	Description	Possible Causes
P0171	System Too Lean (Bank 1)	Vacuum leak, faulty oxygen sensor, dirty mass airflow sensor
P0300	Random/Multiple Cylinder Misfire Detected	Faulty spark plugs, ignition coils, fuel injectors
P0420	Catalyst System Efficiency Below Threshold (Bank 1)	Faulty catalytic converter, exhaust leak, faulty oxygen sensors

8. Sharing OBD2 Data via WhatsApp
