Delphi ANS1047 Nitrogen Oxide (NOx) Sensor - Upstream

Delphi ANS1047 NOx Sensor for Ram Diesel Applications

Delphi ANS1047 is a nitrogen oxide (NOx) sensor built for upstream exhaust monitoring on select Ram heavy-duty diesel trucks. It is engineered with OE development and validation methods to deliver accurate sensor readings for emissions system feedback on 2013-2018 Ram 2500 and 2013-2018 Ram 3500 applications.

Key Features

• Part number ANS1047 nitrogen oxide (NOx) sensor
• Upstream exhaust position
• 12-volt electrical specification
• Gray square connector with 4 terminals
• Male connector and male terminal design
• Universal fit sensor configuration
• 35.066 in. wiring harness length
• OE-tested and calibrated for accurate readings

Detailed Description

Delphi ANS1047 is a replacement NOx sensor for emissions control systems that rely on precise upstream exhaust gas measurement. It is listed for 2013-2018 Ram 2500 and 2013-2018 Ram 3500, making it a direct search match for Ram 2500 NOx sensor upstream replacement and Ram 3500 diesel emissions sensor service. Delphi validates its sensors to OE standards, helping maintain accurate signal output for the vehicle’s emissions monitoring strategy. This part cross-references Standard Ignition NOX011 for the same application.

What It Helps Address

• NOx sensor fault codes related to upstream exhaust monitoring
• Incorrect emissions feedback from the exhaust aftertreatment system
• Check engine lights tied to nitrogen oxide sensor performance
• Driveability issues caused by emissions system sensor errors
• Service needs on 2013-2018 Ram 2500 and 2013-2018 Ram 3500 diesel models

Installation Notes and Tips

Confirm the upstream sensor location before ordering and match the connector style, terminal count, and harness length to the original unit. Verify the vehicle’s year, make, model, and emissions configuration against the listed fitment for 2013-2018 Ram 2500 and 2013-2018 Ram 3500. After installation, clear diagnostic trouble codes and complete any required relearn or monitor procedures according to the vehicle service information.

Quality Assurance

Delphi sensors are developed and validated using OE-level methods and calibrated to OE standards for accurate readings. That focus on testing and calibration supports consistent performance in emissions control service.
