Cummins ISB, ISL Pressure Sensing Tube 2017-2024: OEM 5505841

Dependable Pressure Signal Routing for Cummins ISB & ISL Engines (2017–2024)

What is it?
The Cummins ISB & ISL Pressure Sensing Tube (2017–2024), identified by OEM part number 5505841, is a pressure signal conduit designed for Cummins ISB and ISL diesel engines produced between 2017 and 2024. This tube connects specific intake or exhaust points to onboard pressure sensors, allowing the engine control unit (ECU) to receive accurate pressure information that’s essential for combustion management and emissions system coordination.

Why choose this Pressure Sensing Tube?
Manufactured to Cummins’ original specifications for the ISB and ISL platforms, this tube ensures correct routing and reliable pressure signal delivery. When a pressure sensing tube becomes cracked, pinched, blocked, or disconnected, the ECU may receive inaccurate readings. Incorrect pressure data can lead to mismanaged combustion timing, emissions irregularities, or diagnostic trouble codes. Choosing the correct OEM-specified tube supports dependable pressure communication and helps maintain consistent engine and emissions system behavior.

Key Benefits
✅ Designed specifically for Cummins ISB & ISL engines (2017–2024)
✅ Provides dependable transmission of pressure signals to sensors
✅ Helps support coordinated combustion and emissions control logic
✅ Direct replacement — no adjustments or fabrication needed
✅ Built to endure rugged intake/exhaust environments

Applications
This pressure sensing tube is suitable for medium- and heavy-duty vehicles and equipment powered by Cummins ISB or ISL engines manufactured between 2017 and 2024. Common uses include delivery trucks, vocational work rigs, regional transport vehicles, construction equipment, and industrial diesel platforms where accurate pressure monitoring contributes to optimal performance and emissions compliance.

Installation Notes
Before starting service, allow the engine and intake/exhaust components to cool completely. Inspect the existing tube for signs of cracking, pinching, or contamination prior to removal. Install the replacement tube by routing it properly between the pressure source and sensor connection, ensuring all fittings are secure. Once installed, clear any stored fault codes and verify correct pressure readings using diagnostic tools as part of system testing.

Final Thoughts
If your Cummins-equipped vehicle is displaying pressure-related sensor codes, uneven engine response, or irregular emissions system behavior, replacing a worn or damaged pressure sensing tube with the correct OEM unit can help restore stable pressure monitoring and smoother system operation. The Cummins ISB & ISL Pressure Sensing Tube (OEM 5505841) plays an important role in maintaining accurate communication between pressure sensors and the engine control system.
