Standard Motor Products NOX042 Nitrogen Oxide NOx Sensor

The Standard Motor Products NOX042 is a diesel nitrogen oxide (NOx) sensor designed to monitor nitrogen oxide emission levels in diesel-powered vehicles equipped with selective catalytic reduction (SCR) or NOx adsorber aftertreatment systems. NOx sensors monitor the level of nitrogen oxide emitted by a diesel vehicle to ensure compliance with emissions regulations.

Key Features:

• Direct-fit OE replacement ensures proper fit, form, and function for ease of installation
• Plug and play design, so there's no additional programming required
• Undergoes extensive testing and validation for proper performance and peak reliability
• Designed for high-temperature exhaust environments
• Precision-engineered to meet OE specifications

Standard Motor Products NOx sensors work in conjunction with SCR systems to measure nitrogen oxide levels both upstream and downstream of the catalytic converter. Most engines feature two NOx sensors: an upstream sensor located near the turbo downpipe that measures engine-out NOx, and a downstream sensor that measures NOx levels exiting the SCR catalyst. This critical emissions component helps ensure your diesel vehicle meets environmental compliance standards while maintaining optimal engine performance.
