Automotive-leader O2 Sensor Kit for Honda CR-V 2.4L (2007–2009) — 2‑Piece Upstream & Downstream Heated 4‑Wire

Automotive-leader 2-piece oxygen sensor kit replaces both upstream (234-9062) and downstream (234-4359) O2 sensors for 2007–2009 Honda CR-V 2.4L models, restoring accurate air/fuel monitoring and engine management compatibility.

When oxygen sensors fail or drift, the engine computer receives incorrect oxygen readings, which can affect fuel trim and emissions monitoring. This Automotive-leader kit includes a heated 4-wire upstream sensor and a heated 4-wire downstream sensor, designed as direct-fit replacements for Honda CR-V 2.4L (2007–2009) engines. Each sensor is constructed with high-temperature, corrosion-resistant materials and is bench-tested to meet performance expectations before shipment.

How do these sensors improve engine performance?

Replacing worn or contaminated O2 sensors helps the engine control unit receive accurate exhaust oxygen data, which allows more precise fuel delivery adjustments. That can reduce rough idling, correct long-term fuel trim errors, and improve drivability without altering engine hardware.

• Direct-fit upstream (234-9062) and downstream (234-4359) sensors for proper ECU communication.
• Heated 4-wire design ensures faster sensor warm-up and reliable readings.
• High-temperature materials resist corrosion and extend service life.
• Wire harness lengths ~10.4–10.8 in for correct routing and connector reach.

Will these sensors fit my specific Honda CR-V model?

These Automotive-leader sensors are engineered for 2007–2009 Honda CR-V models with the 2.4L inline-4 gasoline DOHC engine (2354 cc). They are sold as a matched upstream and downstream pair to ensure compatibility and simplify replacement.

• Direct application to CR-V EX, EX-L, and LX trims with 2.4L engines (2007–2009).
• Interchangeable with OE and aftermarket part numbers listed for cross-reference.
• Plug-and-play 4-wire heated connectors match factory wiring harnesses.
• Selected harness lengths tailored to factory routing for a neat installation.

What do the part numbers and interchange listings mean for me?

The kit lists both Automotive-leader part numbers (234-9062 upstream, 234-4359 downstream) plus common OEM and aftermarket cross-reference numbers. Use these interchange numbers to confirm fitment against your vehicle’s existing sensors or service documentation before installing.

• Upstream 234-9062 cross-references include 36531-RZA-013 and several OEM variants.
• Downstream 234-4359 listed alongside 36532-RZA-004 and equivalent codes.
• Cross-references help ensure you choose the correct sensor version for your CR-V.
• Contact technical support if you need help matching numbers to your VIN.

How reliable is the Automotive-leader kit and what support is included?

Automotive-leader subjects each sensor to professional loading tests before shipping and uses materials designed for high-heat, corrosive exhaust environments. The product comes with a two-year warranty and a customer support promise to resolve issues within 24 hours.

• Two-year warranty covering manufacturing defects and premature failure.
• Pre-shipment testing to verify sensor function and wiring integrity.
• Technical assistance and after-sale support with a 24-hour response window.
• Durable construction aimed at resisting high temperatures and corrosion.

Who is this for: This Automotive-leader O2 sensor pair is intended for DIY mechanics and professional technicians replacing failed or aging oxygen sensors on 2007–2009 Honda CR-V 2.4L vehicles. It’s a practical option for owners wanting a direct-fit, heated 4-wire upstream and downstream set that restores correct oxygen sensing, supports emissions system performance, and aligns with factory wiring and mounting points.
