Walker Genuine OE NOx Sensor 1004-1080

Walker Genuine OE NOx Sensor 1004-1080 is built for diesel and gasoline emission systems that rely on accurate nitrogen oxide monitoring. With a specific-fit design, gray female square connector, and OE-style harness length, it supports direct replacement on applications that require a plug-and-play sensor.

Walker Products Genuine OE line focuses on OE-level materials and manufacturing standards for emission control service. Part number 1004-1080 is engineered for selective catalytic reduction (SCR) systems where precise NOx readings help maintain aftertreatment performance and protect downstream components.

Key Features

• Specific-fit NOx sensor for emission control service
• OE connector and harness length for direct replacement
• Gray connector color with square female connector shape
• Silver finish with gloss surface
• Built for high-heat, vibration, and corrosive exhaust environments
• Supports SCR system monitoring on diesel and gasoline applications

Detailed Description

Walker 1004-1080 is a Genuine OE nitrogen oxide sensor designed to deliver accurate exhaust gas measurement in modern aftertreatment systems. It is produced by Tier 1 OE suppliers using materials and precision manufacturing methods aligned with original equipment standards. For drivers and technicians servicing emission systems on domestic and import vehicles, including select Ford and Mercedes-Benz applications, this sensor provides a direct replacement path without connector modification.

This part cross-references A0111531728 and 82383556 for the same application. Use Walker 1004-1080 when replacing a failed NOx sensor in an SCR-equipped vehicle or when addressing emission system faults tied to inaccurate NOx readings.

What It Helps Address

• NOx sensor fault codes
• Incorrect exhaust emissions readings
• SCR system performance issues
• Aftertreatment efficiency problems
• Downstream DPF stress from poor emission control data

Installation Notes and Tips

Confirm the connector style, harness length, and specific-fit application before installation. Match the OE connector shape and gender to the original sensor, and inspect the exhaust-side mounting area for heat damage, corrosion, or wiring wear before swapping in part number 1004-1080. For Ford and Mercedes-Benz NOx sensor replacement jobs, verify the vehicle’s emission system configuration and diagnostic trouble codes before clearing faults.

Quality Assurance

Walker Products Genuine OE sensors are manufactured to OE-level standards and field-tested for demanding exhaust conditions. Part number 1004-1080 is built for dependable operation in SCR-equipped emission systems and is backed by Walker’s technical support and expanding application coverage.
