GDUKOP Oxygen Sensor Kit Upstream & Downstream for Honda 2.4L (CR-V 2012–2019, Accord 2013–2017) — OE Fit, Durable

GDUKOP’s 234-9131 two-piece oxygen sensor kit replaces both upstream and downstream O2 sensors to restore proper air–fuel monitoring and engine responsiveness in compatible Honda models.

If your 2012–2019 Honda CR-V or 2013–2017 Honda Accord 2.4L shows rough idle, hesitation, or a persistent check engine light related to oxygen sensor faults, this matched upstream and downstream sensor set offers a direct-fit repair option. Each sensor is built to OE specifications and uses durable materials that withstand heat and pressure, helping the engine control module get accurate readings for fuel trimming and emissions control.

How does replacing both upstream and downstream sensors improve performance?

Worn or failing oxygen sensors can give the ECU misleading oxygen-level data, which leads to poor fuel metering and drivability issues. Installing a matched upstream (234-9131) and downstream (234-4980) pair helps the system recalibrate and maintain correct air–fuel ratios.

• Upstream part numbers: 234-9131, 36531-5A2-A01 — monitors pre-catalyst combustion.
• Downstream part numbers: 234-4980, 36532-5LA-A01 — verifies catalytic converter efficiency.
• Restores smoother idle and reduces hesitation under load.
• Helps clear OBD-II codes when sensors are the root cause.

What vehicles and engines do these sensors fit?

This GDUKOP oxygen sensor kit is designed as a direct replacement for specific Honda applications that use the 2.4L engine. Confirm compatibility by cross-referencing the OE numbers before purchase.

• Compatible with Honda CR-V model years 2012–2019.
• Compatible with Honda Accord 2.4L model years 2013–2017.
• Matches listed OE numbers for straightforward fitment.
• Check vehicle VIN and part numbers to ensure a perfect match.

How difficult is installation and what tools are needed?

GDUKOP sensors are engineered for plug-and-play replacement with correct wiring and a weather-resistant seal to simplify installation. A basic set of hand tools is usually enough, though rusted exhaust hardware may require penetrating oil and longer-handled tools.

• Designed for straightforward installation with basic hand tools.
• Weather-tight connectors reduce corrosion risk at the plug.
• No ECU reprogramming typically required after sensor replacement.
• Inspect harness and threads for damage before final assembly.

What durability and quality features do these sensors include?

These oxygen sensors are manufactured using high-quality materials to resist extreme under-hood temperatures and pressure cycles. That construction supports long service life and reliable readings under typical driving conditions.

• Built to tolerate high exhaust temperatures and vibration.
• Constructed for consistent electrical performance and response time.
• Sealed connectors and robust housings improve weather resistance.
• OE-equivalent design for fit and function without modifications.

Who is this for: This GDUKOP 2-piece O2 sensor kit is aimed at DIY mechanics and professional technicians maintaining 2012–2019 Honda CR-Vs or 2013–2017 Accord 2.4L models who need a reliable, OE-referenced replacement. It’s well suited for anyone troubleshooting fuel-trim errors, recurring OBD-II oxygen sensor codes, or diminished throttle response due to aging sensors. Verify vehicle fitment against the listed OE part numbers (234-9131/234-4980 and 36531-5A2-A01/36532-5LA-A01) before ordering to ensure compatibility and a trouble-free installation.
