Walker Products 1018-1010 Exhaust Gas Differential Pressure Sensor

The Walker Products 1018-1010 is a heavy-duty Exhaust Gas Differential Pressure Sensor (DPS) engineered as a direct-fit OE replacement for diesel-equipped vehicles. Designed to monitor the performance of the Diesel Particulate Filter (DPF), this sensor measures exhaust gas pressure both upstream and downstream of the filter to deliver accurate, real-time data to the engine control unit (ECU).

By comparing the pressure differential across the DPF, the ECU uses this signal to determine soot saturation levels, manage filter regeneration cycles, and control Diesel Exhaust Fluid (DEF) injection timing. Accurate readings from the DPS are essential for maintaining proper exhaust flow, preserving engine performance, and ensuring compliance with emissions standards.

Key Features:

• Monitors DPF performance by measuring upstream and downstream exhaust gas pressure
• Provides critical data to the ECM for precise regeneration cycle timing and DEF injection control
• Helps detect early DPF clogging to prevent engine derate events and costly exhaust damage
• Engineered to meet or exceed OE specifications for pressure range, signal accuracy, and electrical performance
• Rugged construction resists extreme exhaust temperatures, vibration, and soot contamination
• OE-style connector and direct-fit mounting for quick, hassle-free installation
• Manufactured under ISO 9001/IATF16949 certified quality standards
• Backed by Walker Products' 75+ years of engine sensor and fuel system expertise

Walker Products 1018-1010 is part of Walker's heavy-duty differential pressure sensor lineup, trusted across light-duty and medium-duty diesel platforms for reliable, long-term emissions system performance.
