  • Four methods:

    1.Compare the original factory number on the old sensor.

    2.Check compatibility using your vehicle’s VIN code.

    3.Review the product page’s compatibility details or use Amazon’s compatibility checker.

    4.Consult the parts supplier.

  • Heated-type sensors are recommended for replacement or inspection around 60,000 miles, and non-heated types around 30,000 miles.

  • Yes；however, if you lack prior installation experience, we recommend seeking assistance from a professional technician.

  • Some vehicles need an ECU reset or sensor adaptation. The fault light might not mean an oxygen sensor problem.

    1.Read fault codes with a diagnostic tool.

    2.Check wiring or related issues (e.g., catalytic converter) and analyze the codes.

Sensor has no issues and compatability was confirmed. Ford Sync diagnostics reads the data properly as if it was OEM part. Great price point!

Installed this O2 sensor on my Toyota Camry in under 20 minutes – plug-and-play just like the description said. The check engine light turned off after a short drive, and my MPG improved noticeably. For the price, this beats paying dealership rates.

Bought this for my Honda that kept throwing a P0420 code. After struggling with a cheap generic sensor last year (that died in 3 months), this one feels solid. Took me 10 minutes with a YouTube tutorial. Three weeks in, no codes and smoother acceleration.
