BELKEBIR Oxygen O2 Sensor Kit for Honda 2.4L — 2PCS Replacement (234-4797/234-9040), Direct Fit

If your Honda’s engine light, fuel economy, or throttle response has slipped, worn oxygen sensors are often the cause. This two-piece BELKEBIR O2 sensor set is engineered to match the fit and function of original equipment for many Honda Accord 2.4L models, delivering quick feedback to the engine control unit so combustion stays in balance.

Which Honda models and years will this O2 sensor fit?

The sensors are intended for Honda Accords equipped with the 2.4L inline-4 engine across several model years. Confirm your vehicle’s engine code and connector style before ordering to ensure proper fitment.

• Compatible with Honda Accord: 2003–2005 Accord DX, 2003–2007 Accord EX and LX 2.4L L4
• Also fits 2006–2007 Accord VP and 2007 Accord SE 2.4L L4
• Check part numbers and connector shape against your vehicle prior to purchase

How does this replacement improve performance and fuel economy?

A healthy oxygen sensor supplies accurate oxygen readings to the ECU so the engine can maintain optimal air-fuel ratio. Replacing a degraded sensor reduces running rich or lean conditions that cause higher fuel use and hesitation.

• Provides real-time oxygen data to the engine control unit for stable combustion
• Helps recover lost miles-per-gallon caused by an out-of-spec sensor
• Can smooth acceleration and reduce rough idling tied to incorrect fuel trims

What materials and testing standards ensure reliability?

These BELKEBIR sensors use durable sensing elements and housing designed to withstand exhaust temperatures and contaminants. Each unit undergoes quality checks to validate signal response and longevity under typical driving conditions.

• Platinum and ceramic sensing construction for consistent, high-temperature performance
• Robust housings and connectors to resist vibration and exhaust corrosion
• Factory testing to confirm electrical response and fitment before shipping

What warranty and part references should I expect?

The kit includes two sensors and is backed by a 12-month warranty for peace of mind. It is sold as a direct replacement for several OE and aftermarket reference numbers—match these to your vehicle parts list.

• Replaces OE references including 234-4797, 234-9040 and equivalents
• Includes a 12-month limited warranty against defects
• Ships as a two-piece set for upstream/downstream or dual-sensor applications

Who is this for: This BELKEBIR 2PCS O2 sensor kit is aimed at Honda owners, DIY mechanics, and independent shops needing a reliable, cost-effective replacement for failing oxygen sensors on 2.4L Accord engines. If you’ve confirmed the part numbers or need to replace both sensors at once to restore fuel economy and engine smoothness, this kit provides a matched pair built for durability and accurate feedback.
