  Description:

  Genuine OEM Nissan Rear Heated Oxygen Sensor — Part # 226A0-1KT0A

  Restore proper emissions monitoring and fuel management to your Nissan Versa or Versa Note with the factory-correct rear (downstream) oxygen sensor. This genuine OEM heated O2 sensor monitors exhaust gas composition downstream of the catalytic converter — providing feedback to the ECM to verify catalytic converter efficiency and maintain proper fuel trim on the 1.6L HR16DE engine. Direct factory fit, correct connector, correct thread pitch.

  Part Details:

  • Part Number: 226A0-1KT0A
  • Other Names: Heated Oxygen Sensor Rear, HO2S Rear, Downstream O2 Sensor, Rear Oxygen Sensor, Sensor O2
  • Condition: New, Genuine OEM Nissan
  • Position: Rear (Downstream / Post-Catalytic Converter)
  • Type: Heated Oxygen Sensor (HO2S)
  • Application: 1.6L HR16DE engine — Sedan body style

  ⚠️ Production Date & Body Style Note:

  • Versa Sedan: Fits to 08/2017 production
  • Versa Note: Fits to 08/2018 production
  • This sensor fits the Sedan body style — confirm your body style with your VIN before ordering

  Compatible Vehicles:

  • 2012–2019 Nissan Versa Sedan (1.6L HR16DE — to 08/2017)
  • 2014–2018 Nissan Versa Note (1.6L HR16DE — to 08/2018)

  Always confirm fitment using your VIN and production date before purchasing.

  Why buy OEM? Aftermarket oxygen sensors frequently use incorrect signal output characteristics, wrong connector housings, or inferior sensing elements that trigger persistent check engine lights even after replacement. The genuine Nissan sensor is calibrated to the exact signal parameters the HR16DE ECM expects — for a reliable, code-clearing installation.

  Symptoms this part fixes:

  • Check engine light with downstream O2 sensor fault codes (P0136, P0137, P0138, P0139, P0140, P0141)
  • Catalyst efficiency fault codes (P0420) — downstream sensor plays a key role in catalyst monitoring
  • Poor fuel economy without obvious cause
  • Erratic or slow downstream O2 sensor response on live data
