Overview
Upstream (inlet) NOx sensor is an emissions system sensor installed ahead of downstream aftertreatment stages to measure nitrogen oxide levels in the exhaust stream. It helps provide real-time input to the engine and aftertreatment control system, supports emissions-related adjustments, and contributes to stable exhaust system performance in heavy-duty diesel applications.
