- Rectangular connector design for a secure electrical connection.
- Female connector with six male pin terminals.
- Direct-fit electrical configuration for listed applications.
Detailed Description
Standard Ignition NOX039 is built for vehicles that rely on accurate nitrogen oxide measurement to support emission system operation. The sensor’s upstream location places it where exhaust data is captured before downstream treatment, helping the control system monitor emissions performance on the Chevrolet Express 2500, Chevrolet Express 3500, GMC Savana 2500, and GMC Savana 3500.
The connector layout includes one rectangular female connector and six male pin terminals, which helps ensure proper electrical mating during replacement. For buyers searching for a NOx sensor for 2017-2019 Chevrolet Express 2500 upstream or a NOx sensor for 2017-2019 GMC Savana 3500 upstream, NOX039 provides the specified fitment and connector style.
What It Helps Solve
- Fault codes related to NOx sensor performance.
- Incorrect exhaust emissions readings.
- Failed upstream sensor signal transmission.
- Connector mismatch during sensor replacement.
Installation Notes and Tips
Verify the upstream sensor location and connector style before installation. Match the rectangular female connector and six-pin terminal layout to the original part. Confirm vehicle application by year, make, model, and position before ordering.
Quality Assurance
Standard Ignition supplies emission control sensors for replacement applications that require accurate electrical fitment and consistent signal communication. Part number NOX039 is also referenced as DNX039 and NOX1039 in interchange listings.
