【Function】Most engines have two NOx sensors. Upstream and downstream sensors. The NOx sensor monitors the level of NOx emitted from the diesel vehicle to ensure compliance with emissions regulations. Common causes of failure include soot buildup on the sensor, eco-water intrusion and/or cable damage, which will cause the check engine light to come on. This upstream nitrogen-oxygen sensor is a good solution to this problem.
【Easy Install】Direct replacement, simply remove the old or damaged nitrogen oxide sensor and directly install the new one. Our products are tested with materials and vehicle test drives prior to shipment, and the upstream NOx sensors are durable and stable. Made from high quality materials, our NOx sensors offer high performance and NOx sensor replacements that fully meet or exceed OEM standards.
