  • 【Complete 2-Pcs Repair Solution】Package includes 1x upstream air-fuel ratio sensor (equivalent to Denso 234-5055) and 1x downstream oxygen sensor (equivalent to Denso 234-4568). Replacing worn sensors may help resolve related Check Engine light issues, improve fuel-trim response, and support proper emissions-system monitoring.
  • 【OEM Fit & Easy Installation】 Built to match the connector and wiring configuration used on compatible Nissan and Infiniti applications. The factory-style connector is designed for direct-fit installation without manual wire splicing. Always verify the part number, connector, vehicle year, engine, and sensor position before ordering.
  • 【Advanced Wideband Tech Calibration】 The upstream wideband sensor is designed to provide fuel-trim feedback to the ECU, while the downstream sensor monitors catalytic-converter performance. Correct compatibility is essential for accurate signal communication and reliable operation.
  • 【Heavy-Duty Structural Build】 Features a dual-layered laser-welded stainless steel body housing a premium zirconium sensing core. Designed to withstand the extreme exhaust manifold temperatures and thermal shock typical of modern daily driven passenger cars and SUVs.
  • 【Important Engine Type Note】 This kit is engineered exclusively for standard gasoline models. Does NOT fit Hybrid variants.For 3.5L V6 applications, verify the required engine bank and sensor position before ordering.
Related Diagnostic Trouble Codes

A faulty oxygen sensor may contribute to the following diagnostic trouble codes. These codes can also have other causes, so proper diagnosis is recommended before replacement.

  • Upstream (Sensor 1) Errors: P0031, P0032, P0130, P0131, P0132, P0133, P0135 (Cures raw exhaust odors, low acceleration power, and engine hesitation)
  • Downstream (Sensor 2) Errors: P0136, P0137, P0138, P0139, P0140, P0141 (Resolves catalytic converter tracking errors)
  • System Trims: P0171 (System Too Lean), P0172 (System Too Rich)
