Walker 274-1031 Exhaust Gas Differential Pressure Sensor

Overview

Walker 274-1031 is an OE replacement exhaust gas differential pressure sensor for diesel emissions systems. It measures pressure across the diesel particulate filter so the engine control module can manage regeneration timing and monitor restriction levels.

Fits 2016-2019 Nissan TITAN XD, N/A. This part cross-references Dorman - HD Solutions 904-7127 and Standard Ignition DPS101 for the same application.

Key Features

• OE replacement sensor for diesel exhaust pressure monitoring
• Factory-matched connector design for straightforward electrical connection
• Rugged construction for heat, vibration, and soot exposure
• Built to meet or exceed OE pressure range, signal accuracy, and electrical performance
• Black housing with oblong shape, 4-pin male terminals, and 2 ports

Detailed Description

Walker 274-1031 is engineered for diesel exhaust systems that rely on accurate differential pressure data to manage DPF regeneration and emissions control. By reporting pressure changes across the filter, the sensor helps the ECM identify restriction conditions early, which supports cleaner operation and reduces the risk of drivability problems tied to soot buildup or derate events. Walker 274-1031 is built for harsh exhaust conditions and uses an OE-style fit with factory-matched connectors for a direct replacement on the listed Nissan TITAN XD application.

Walker Products focuses on precision replacement sensors for diesel platforms, and this exhaust gas differential pressure sensor reflects that approach with OE-matched performance targets and durable construction. For buyers searching for a Nissan TITAN XD exhaust gas differential pressure sensor or Walker 274-1031 replacement, this unit is specified for the listed fitment and emissions-system function.

What It Is Used For

• Incorrect DPF pressure readings
• Delayed or improper regeneration control
• Soot buildup that can trigger emissions faults
• Restriction-related drivability issues
• Engine derate conditions caused by clogged filter monitoring errors

Installation Notes

Verify connector style, terminal layout, and port configuration before installation. Confirm the sensor location and inspect related hoses and electrical connections for soot contamination, heat damage, or blockage. Use the listed fitment only: Fits 2016-2019 Nissan TITAN XD, N/A.

Quality Assurance

Walker 274-1031 is manufactured to meet or exceed OE specifications for pressure range, signal accuracy, and electrical performance. Its rugged sensor design is intended for the demanding exhaust environment found in diesel emissions systems.
