ACDelco NOx Nitrogen Oxide Sensor

The ACDelco NOx Nitrogen Oxide Sensor (also called a NOx sensor or nitrogen oxide sensor) measures the level of nitrogen oxides in the exhaust stream of diesel and other emissions-controlled engines. It sends that data to the engine control module, which uses it to monitor emissions system performance.

Key Features:

• Monitors nitrogen oxide levels in the exhaust to support proper emissions control system operation
• Gives the engine control module accurate feedback for selective catalytic reduction (SCR) and aftertreatment strategies
• Designed to meet ACDelco's quality standards for reliable performance and durability
• Built for dependable operation in high-temperature exhaust conditions
• Helps restore proper emissions system function when replacing a failed or degraded sensor

A faulty NOx sensor can trigger check engine or emissions warning lights and may reduce engine performance. Replacing it with an ACDelco sensor helps maintain emissions compliance and the vehicle's aftertreatment system performance. ACDelco is a trusted name in replacement parts.
