URO 11787589122 Rear Oxygen Sensor Post-Catalytic Converter O2 Sensor

The URO 11787589122 is a high-quality rear oxygen sensor designed for post-catalytic converter installation. This downstream O2 sensor monitors exhaust oxygen levels after the catalytic converter, providing critical data to the engine control unit (ECU) for optimal fuel mixture adjustments and emissions compliance.

Key Features:

• Post-catalytic converter (downstream) oxygen sensor positioning
• Delivers precise readings of oxygen levels in exhaust gases
• Enables ECU to make essential adjustments for improved combustion efficiency
• Durable construction engineered to withstand extreme exhaust system conditions
• Direct replacement for OEM part number 11787589122
• ISO/IATF 16949 quality management system certified manufacturing

Replacing a faulty oxygen sensor is essential for maintaining engine efficiency, preventing reduced fuel economy, minimizing emissions, and avoiding check engine light warnings. This sensor helps ensure your engine management system operates at peak performance while maintaining compliance with emissions regulations.
