Description
xUpgrade your Nissan Altima’s O2 sensing with the Dasbecan Oxygen O2 Sensor pair, designed to mirror OEM standards for 2013–2017 Altima 2.5L models. This twin-sensor kit includes both upstream and downstream sensors and is built to endure the engine environment while delivering reliable signals that support efficient engine management. By replacing the original components, you can refresh the air-fuel sensing loop and maintain smooth drivability across daily commuting and open-road trips.
Overview and compatibility
The kit targets 2.5L inline-4 Altima trims from 2013 through 2017, covering Base, S, SV, SL, and SR variants. It replaces OEM numbers 234-9133 (upstream) and 234-4905 (downstream), offering a straightforward, direct-fit solution that mirrors the form and function of the original sensors. The sensors are designed to align with factory electrical interfaces, so you can install with confidence and minimal downtime.
What’s included and fitment

- Downstream sensor 234-4905
- Direct replacement, plug-and-play design
- Full kit covers both sensors for complete O2 system renewal
Durability and performance
Manufactured with durable materials and an emphasis on resistance to the conditions inside the exhaust and engine bay, these sensors feature waterproof and dustproof construction along with corrosion and heat resistance. The result is a more stable sensing performance across varying driving conditions, helping to maintain consistent fuel-signal feedback without frequent sensor failure.

Swap out the old units, connect the harnesses, and you’re back on the road without the need for extensive wiring or calibration. Real-world use includes everyday commutes, family trips, and highway drives where reliable O2 readings contribute to smoother acceleration, steadier idle, and improved throttle response in typical driving scenarios.
