234-4461 Downstream Oxygen Sensor, Rear Post-Catalytic O2 Sensor Replacement Compatible with Select Honda & Acura Vehicles (2007–2014)

TenutaRealX 234-4461 Downstream Oxygen Sensor – Rear Post-Catalytic Replacement The TenutaRealX 234-4461 downstream oxygen sensor is designed as a direct replacement component for select Honda and Acura vehicles, intended for installation in the rear (post-catalytic converter) position. This single downstream O2 sensor is manufactured to meet industry specifications and is engineered to monitor oxygen content in exhaust gases, providing data feedback to the vehicle’s engine control system when installed on compatible applications. Vehicle Compatibility (Reference Only) Compatible with select models, including: Honda Accord, Odyssey, Pilot, Ridgeline (2007–2014, 3.5L V6) Acura MDX, TL, TSX (2007–2014, 3.2L / 3.5L / 3.7L) Please verify model year, engine type, and sensor position before purchase. TenutaRealX Design Features This rear oxygen sensor features a protective coating designed to resist common exhaust-related contaminants and a fast-response ceramic heater to support stable sensor operation in high-temperature exhaust environments. The OE-style design allows for proper fitment and connection on compatible vehicles.

• Designed as a replacement for OE part number 234-4461, this downstream oxygen sensor is compatible with select Honda and Acura vehicles (2007–2014). Please verify vehicle fitment and sensor position (rear/post-catalytic converter) before ordering.
• This sensor is intended for use in the rear oxygen sensor location, positioned after the catalytic converter. It is not designed for upstream or air-fuel ratio sensor applications.
• Engineered to measure oxygen content in exhaust gases and provide feedback data to the vehicle’s engine control unit (ECU), supporting normal engine management operation when used on compatible vehicles.
• Features an OE-style electrical connector and factory-style mounting design for direct installation. No wire cutting, splicing, or modification required on compatible models.
• Constructed with heat-resistant materials and a double-layer protective shield, designed to withstand high exhaust temperatures and harsh operating conditions typical of downstream sensor locations. Includes 1 × Downstream Oxygen Sensor. Single sensor only. Designed specifically for rear (post-catalytic converter) installation.
