ACDelco 12741485 Nitrogen Oxide (NOx) Sensor

The ACDelco 12741485 is a genuine GM OE nitrogen oxide (NOx) sensor designed to monitor exhaust emissions in diesel and gasoline vehicles. This sensor plays a critical role in modern emission control systems by measuring nitrogen oxide levels in the exhaust stream, allowing the engine control module to optimize performance and maintain compliance with emission standards.

Key Features:

• Genuine GM Original Equipment part designed and engineered to GM specifications
• Monitors NOx levels in exhaust gases for emission control system optimization
• Precision-engineered sensor element for accurate readings across varying temperatures
• Direct-fit replacement for specific GM vehicles requiring this part number
• Designed, tested, and backed by General Motors for reliable performance
• Works with the vehicle's onboard diagnostics system to ensure proper emissions compliance

ACDelco OE parts undergo rigorous testing to meet the same quality standards as the original equipment installed at the factory. This NOx sensor is essential for maintaining proper engine performance, fuel efficiency, and compliance with emissions regulations while preventing check engine light codes related to NOx sensor failures.
