Product Overview

Maintain optimal engine performance and emissions efficiency with our high-precision Exhaust Gas Pressure Sensor. Designed specifically for Cummins heavy-duty diesel engines, this sensor monitors exhaust backpressure to ensure the Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) systems operate within factory specifications.

A failing pressure sensor can lead to increased fuel consumption, loss of power, and potential DPF clogging. Our premium replacement unit provides fast, accurate signal feedback to the Engine Control Unit (ECU), helping your vehicle maintain compliance and peak performance under heavy loads.

Technical Features

  • OEM Fit & Function: Engineered to match the exact signal characteristics and physical specifications of original Cummins sensors.

  • Thermal & Pressure Resilience: Built with specialized materials to withstand high-temperature exhaust gases and extreme vibration.

  • Rapid Response: High-sensitivity technology ensures real-time pressure monitoring, preventing engine management faults.

  • Easy Installation: Direct “plug-and-play” connector matches standard Cummins wiring harnesses for efficient maintenance.

Vehicle & Engine Compatibility

This sensor is a standard component for many Cummins-powered applications:

  • Engine Series: ISB, ISC, ISL, ISM, ISX, and QSB engines.

  • Common Applications: Used extensively in Class 8 trucks, heavy-duty commercial buses, and industrial power generation systems.

  • Manufacturer Integration: Compatible with vehicles equipped with Cummins power plants, including Freightliner, Peterbilt, Kenworth, and RAM trucks (6.7L Cummins).
