Reconnect your emissions system's NOx sensor with the Standard Ignition Nitrogen Oxide (NOx) Sensor Connector S3072. This is the electrical connector that mates the vehicle harness to the NOx sensor, and it drops in as a direct-fit replacement for the 2010-2016 Chevrolet Express 2500, 3500 and 4500; 2010-2016 GMC Savana 2500, 3500 and 4500; 2011-2016 Chevrolet Silverado 2500 HD and 3500 HD; and 2011-2016 GMC Sierra 2500 HD and 3500 HD.
Function: Provides the wiring connection between the vehicle's harness and the NOx sensor so the sensor's signal can reach the control module.
Direct fit: A direct-fit replacement connector for the listed applications.
Purpose: Serves as a replacement for a damaged or corroded original connector.
Over time a NOx sensor connector can suffer corroded, melted, or spread terminals that cause an intermittent or lost signal. If a failed connector is the cause of that fault, replacing it with S3072 restores the connection. Diagnose the circuit first, since sensor or wiring issues can produce similar symptoms.
Interchange: Manufacturer part number S3072.
