3. Diagnosing Car Problems with the Konnwei KW902
Once your Konnwei KW902 is set up, you can start diagnosing car problems. Here’s how to interpret the data and codes:
3.1. Reading and Interpreting Diagnostic Trouble Codes (DTCs)
DTCs are codes that indicate specific problems with your vehicle. They typically consist of a letter followed by four numbers (e.g., P0300). The letter indicates the system affected:
- P: Powertrain (engine, transmission)
- B: Body (interior, airbags)
- C: Chassis (brakes, suspension)
- U: Network (communication systems)
The numbers provide more specific information about the problem. For example, P0300 indicates a random or multiple cylinder misfire.
3.2. Common DTCs and Their Meanings
| DTC | Description | Possible Causes |
|---|---|---|
| P0300 | Random/Multiple Cylinder Misfire Detected | Faulty spark plugs, ignition coils, fuel injectors, vacuum leaks |
| P0171 | System Too Lean (Bank 1) | Vacuum leaks, faulty O2 sensor, fuel pump issues |
| P0420 | Catalyst System Efficiency Below Threshold (Bank 1) | Faulty catalytic converter, O2 sensors |
| P0113 | Intake Air Temperature Sensor Circuit High Input | Faulty IAT sensor, wiring issues |
| P0301 | Cylinder 1 Misfire Detected | Faulty spark plug, ignition coil, fuel injector |
3.3. Clearing Codes and Resetting the Check Engine Light
After addressing the issue indicated by a DTC, you can clear the code using the Konnwei KW902 and the OBDII app. Simply select the option to clear codes in the app. Keep in mind that clearing a code does not fix the underlying problem; it only turns off the check engine light. If the problem persists, the code will reappear.
3.4. Live Data Monitoring: What to Look For
The Konnwei KW902 allows you to monitor real-time data from your vehicle’s sensors. Here are some key parameters to watch:
- Engine Coolant Temperature: Indicates the temperature of the engine coolant. Overheating can lead to serious engine damage.
