General Recommendations and Data Validation
Part Number Verification: Verify compatibility by entering the VIN number through the Hyundai EPC system or a third party platform (e.g. RockAuto);
Diagnostic tool: Use GDS2 or TechStream to read oxygen sensor voltage waveform (normal range: 0.1-0.9V fluctuation for front oxygen, 0.2-0.6V stable for rear oxygen);
Cost optimization: Purchasing the sensor by yourself can save 20%-40% of the labor cost, but note that plug-in hybrid models need special programming;
Technology upgrade: Shengmi-Tech's new 4O2-LF-5000PPM sensor (resolution 0.5ppm) is suitable for high-precision testing scenarios.
(Note: The above prices may fluctuate ±15% due to regional and channel differences. For real-time data, we recommend checking RepairPal or local dealers).
