Product Overview

The Cummins Pressure Sensor 3408517 is a high-precision, ceramic capacitive or piezoresistive sensor designed for critical pressure monitoring in diesel engines and aftertreatment systems. It delivers real-time data to the Engine Control Module (ECM) to optimize combustion efficiency, emission control, and system diagnostics.

Core Functions

Emission Control

Monitors SCR air pressure (e.g., for urea dosing systems), triggering ECM alerts (e.g., DTC 4238) if pressure falls below 330 kPa.
Ensures precise AdBlue® injection to meet EPA Tier 4/Euro VI standards.
Fuel System Management

In high-pressure variants, measures common rail fuel pressure (up to 2,500 bar) for optimal injection timing.
Fault Diagnostics

Detects leaks/clogs in air/fuel circuits; activates engine derate for critical failures.

Technical Features

Robust Construction:

Stainless-steel housing with IP6K9K sealing (dust/waterproof).
Media-compatible diaphragm (resists diesel, urea, exhaust gases).
Signal Integrity:

EMI-shielded circuitry for noise immunity in high-vibration environments.
Temperature compensation for drift-free readings.
Plug-and-Play:

Pre-calibrated for Cummins ECMs (e.g., 3408389); no field programming required.
