The Konnwei KW820 is a powerful and versatile OBDII OBD2 EOBD code reader designed to diagnose engine problems in most vehicles. This comprehensive review explores its features, functionality, and vehicle compatibility.
Key Features of the KW820 OBDII OBD2 EOBD Scanner
The Konnwei KW820 offers a wide array of features for diagnosing and troubleshooting vehicle issues:
- Read and Clear Codes: Easily read and clear generic (P0, P2, P3, U0) and manufacturer-specific (P1, P3, U1) diagnostic trouble codes (DTCs). This allows you to identify the root cause of the check engine light (MIL).
- Live Data Stream: View real-time data from the vehicle’s sensors, including oxygen sensor readings, engine speed, and coolant temperature, allowing for dynamic monitoring of engine performance. This feature is invaluable for diagnosing intermittent problems.
- Freeze Frame Data: Capture a snapshot of the vehicle’s operating conditions at the moment a fault code was set. This data can help pinpoint the conditions that triggered the issue.
- I/M Readiness: Check the status of the vehicle’s emissions system monitors to ensure compliance with state regulations before an emissions test. This ensures your vehicle is ready for inspection.
- O2 Sensor Test: Specifically test the functionality of the vehicle’s oxygen sensors, crucial components for fuel efficiency and emissions control. A faulty O2 sensor can significantly impact performance.
- On-Screen DTC Definitions: Provides definitions of DTCs directly on the device’s screen, eliminating the need for external lookups and saving valuable time.
- Vehicle Information Retrieval: Retrieve essential vehicle information such as the Vehicle Identification Number (VIN), Calibration Identification Number (CIN), and Calibration Verification Number (CVN).
