Genuine Nissan Upstream Air-Fuel Ratio Oxygen Sensor (OE 22693-3TY0B)

Is your Nissan suffering from a sudden drop in gas mileage, hesitation during acceleration, or a persistent P0420 or lean/rich fault code? The culprit is likely a tired upstream oxygen sensor. The Genuine Nissan Upstream Air-Fuel Ratio Sensor is a factory-original replacement part built explicitly to maintain your engine's precise combustion metrics. Operating as an advanced wideband sensor positioned before the catalytic converter, it continuously sniffs exhaust gases and reports oxygen levels to the ECU in milliseconds. Replacing a contaminated, lazy stock sensor with this factory-boxed unit ensures your engine injects the exact amount of fuel required, protecting your catalytic converter from unburnt fuel damage and restoring showroom-level efficiency.

Key Features

• 100% Authentic Factory Nissan Part: Designed and engineered by Nissan specifically for your vehicle's engine management system, eliminating aftermarket signal calibration issues.

• Precision Wideband Technology: Monitors real-time air-fuel ratios with tight precision to deliver data smoothly across varying throttle conditions.

• Integrated Fast-Acting Internal Heater: Reaches optimal operational temperatures in seconds, minimizing cold-start emissions and engine hesitation.

• Pre-Applied Anti-Seize Compound: Features factory-coated threads right out of the box to ensure smooth installation and prevent exhaust pipe thread galling.

Performance & Benefits

• Restored Fuel Economy: Feeds clear, lightning-fast data back to your vehicle's computer to optimize the fuel trim, preventing the engine from running rich and wasting gas.

• Ultra-Smooth Acceleration: Eliminates flat spots, engine surges, and throttle lagging by stabilizing air-to-fuel ratios under load.

• Guaranteed OBD-II Compliance: Extinguishes sensor-related check engine lights (CEL) to help your vehicle confidently pass state or local emissions testing.

Vehicle Compatibility

This oxygen sensor is a direct-fit factory component designed for specific upstream (Sensor 1) locations on Nissan platforms:

• Make: Nissan

• Model Applications: Altima, Pathfinder, Rogue, Sentra, and Murano configurations

• Engine Group: Primarily optimized for Nissan 2.5L 4-Cylinder (QR25DE / PR25DD) and 3.5L V6 (VQ35DE) powertrains

• Fitment Position: Upstream (Exhaust Manifold / Before Catalytic Converter)

• Cross-Reference OE Part Number: 22693-3TY0B (Also replaces legacy or superseded configurations: 22693-3TY0A, 22693-1KC0A)

Fitment Tip: Upstream (Sensor 1) and Downstream (Sensor 2) sensors are completely different in function and plug layout. This is an upstream sensor only.
