Delphi ANS1046 Nitrogen Oxide (NOx) Sensor - Downstream

Delphi ANS1046 NOx Sensor for Ram Diesel Applications

The Delphi ANS1046 is a downstream nitrogen oxide (NOx) sensor built for 2013-2014 Ram 2500 and 2013-2014 Ram 3500 applications. It uses OE-focused development and validation methods to deliver accurate sensor readings for emission control diagnostics and system performance.

With a 12-volt design, black oval connector, 4 male terminals, and a 15.366-inch wiring harness length, this NOx sensor is built for direct replacement use in the specified downstream location. Delphi ANS1046 is a practical choice for Ram 2500 and Ram 3500 owners needing a replacement NOx sensor that matches the original application requirements.

Detailed Description

Delphi ANS1046 is an emission control sensor for downstream NOx monitoring on select Ram diesel trucks. It is calibrated to OE standards and validated through Delphi’s sensor development process to support accurate readings, which is important for emissions-related fault detection and drivability diagnostics. This part cross-references Standard Ignition NOX013 for the same application.

For buyers searching for a downstream NOx sensor for 2013-2014 Ram 2500 or 2013-2014 Ram 3500, ANS1046 provides the specified connector style, terminal layout, and harness length needed for the listed vehicle applications. The part number ANS1046 is also useful when verifying replacement options against service information or existing sensor markings.

What It Helps Address

• NOx sensor fault codes
• Emission control warning lights
• Incorrect downstream NOx readings
• Failed emissions inspection results tied to sensor issues
• Replacement needs for a worn or damaged downstream sensor

Installation Notes and Tips

Confirm the vehicle is a 2013-2014 Ram 2500 or 2013-2014 Ram 3500 with the downstream sensor position before ordering. Match the connector shape, terminal count, and harness length to the original part to avoid fitment issues. Verify the part number ANS1046 against the removed sensor and vehicle service information before installation.

Quality Assurance

Delphi sensors are developed and tested to OE standards, with calibration and validation processes aimed at accurate readings and reduced comebacks. That OE-focused approach supports consistent replacement quality for emission control service.
