QIYBONE O2 Sensor Kit for 2013–2017 Nissan Altima 2.5L (2pc) — Upstream & Downstream, OEM-style Fit

QIYBONE's two-piece oxygen sensor kit replaces both upstream and downstream O2 sensors for 2013–2017 Nissan Altima 2.5L models to restore accurate air/fuel monitoring and drivability.

If your Altima is showing rough idle, reduced fuel economy, or a check-engine light tied to O2 sensors, this pair from QIYBONE offers a direct-fit replacement for affected 2013–2017 2.5L L4 trim levels. The set matches OE-style connectors and thermal-resistant stainless-steel housings to meet factory fitment and withstand exhaust temperatures, giving you a straightforward swap without custom wiring.

Which Nissan Altima models and years does this kit fit?

• Compatible years: 2013, 2014, 2015, 2016, 2017
• Engine: 2.5L L4 (four-cylinder)
• Trims included: Base, S, SL, SR (2016–2017), SV, Advance/Sense
• OEM cross-references: 234-9133, 234-4905, 22693-3TA0A, 226A0-3TA0B and similar

How does swapping both upstream and downstream sensors help performance?

Replacing both sensors ensures the engine control module receives accurate readings before and after the catalytic converter, improving fuel trim calibration and overall combustion management. When both sensors operate correctly together, you reduce the chance of persistent error codes and uneven fuel delivery that affect drivability.

• Upstream (pre-cat) sensor monitors air/fuel mixture for instant ECU adjustments
• Downstream (post-cat) sensor verifies converter efficiency and detects leaks
• Pair replacement minimizes false diagnostics and recurring check-engine lights
• Correct readings support smoother idle and more consistent MPG

What are the build and installation features of these QIYBONE sensors?

QIYBONE manufactures these sensors with stainless-steel housings and heat-resistant internals for long-term durability in exhaust conditions. They arrive as plug-and-play units matching OEM connector shapes so you can install them with standard hand tools in most cases.

• Materials: stainless steel, high-temperature-resistant elements for durability
• Design: OEM-spec connectors for direct-fit, no cutting or splicing required
• Installation time: typically a few minutes per sensor with basic tools
• Packaging: supplied as a two-piece kit (upstream and downstream)

Which reference numbers correspond to these replacement sensors?

The QIYBONE sensors cross-reference several OE and aftermarket part numbers to help ensure you choose the right kit for your Altima. Check fitment by comparing the connector and part number references before purchase.

• Common references included: 234-9133 and 234-4905
• Additional OE cross-refs: 22693-3TA0A, 226A0-3TA0B and variants
• Also listed against legacy numbers like 211500-7600 / 211500-7590
• Verify by matching your original sensor’s plug and part number

Who is this kit for: drivers who own a 2013–2017 Nissan Altima with the 2.5L four-cylinder engine and need a dependable, OEM-style replacement for failed upstream and downstream oxygen sensors. It’s a practical choice for DIY mechanics or technicians seeking a cost-effective, direct-fit pair that restores accurate air/fuel sensing without wiring modifications.
