Check engine light on with a P0138 or poor fuel mileage? This OEM Nissan Oxygen Sensor (Part #226A0-5RB0A) restores accurate air/fuel monitoring to help maintain emissions performance, fuel economy, and engine drivability.

Oxygen Sensor (226A0-5RB0A) – OEM Replacement Part for Nissan

The oxygen sensor (also known as the O2 sensor) monitors exhaust gas composition to help the engine control module (ECM) adjust fuel delivery for optimal combustion. This genuine Nissan sensor delivers factory-spec voltage response and sensor heater performance — crucial for passing emissions inspections and preventing drivability issues.

Specifications:
Part Type: Heated Oxygen Sensor (HO2S)
Function: Measures oxygen content in exhaust gases to fine-tune air/fuel ratio
Construction: OEM-grade zirconia or titania element with integrated heater
Position: Varies by application – upstream (pre-cat) or downstream (post-cat); verify fitment by VIN
Includes: One sensor with factory connector and heat shielding

Compatible Nissan Models:
2018–2025 Nissan Altima – 2.5L (L34US)
2018–2025 Nissan Kicks – 1.6L (P15XUS)
2013–2019 Nissan Versa Note – 1.6L (E12XUS)
2011–2025 Nissan Versa Sedan – 1.6L (N17XUS, N18XUS)
May fit additional trim levels or sensor positions. Please check VIN for compatibility.

Key Features:

• Genuine Nissan sensor ensures fast voltage response for accurate air/fuel corrections

• Integrated heater allows quicker warm-up and closed-loop operation

• Helps optimize fuel economy and lower emissions

• Direct-fit connector and length for plug-and-play installation

• Built to resist high-heat and exhaust contamination

• Maintains proper catalytic converter efficiency

Failing to Replace a Faulty O2 Sensor Can Lead To:

• Check Engine Light – Common codes: P0138, P0140, P0420

• Poor Fuel Economy – Excessive fuel trimming due to incorrect O2 readings

• Failed Emissions Test – O2 sensor is critical to catalytic converter monitoring

• Rough Idle or Hesitation – Inaccurate data disrupts fuel control logic

• Catalyst Damage – Unburnt fuel from faulty readings may overheat the converter

Related Components to Inspect or Replace:

• Catalytic Converter – May be affected by prolonged O2 failure

• Exhaust Gasket or Manifold – Check for leaks upstream or downstream

• Wiring Harness or Connector – Ensure no melting or corrosion

• Mass Air Flow Sensor – Works in conjunction with O2 for AFR management

• Fuel Injectors – Dirty or leaking injectors may trigger rich/lean codes

Order with Confidence:
Order the Oxygen Sensor (226A0-5RB0A) to restore your Nissan’s fuel control and emissions compliance. Trust Chapman Nissan to supply factory-fit electrical components designed for accuracy and durability.
