This is a genuine HONDA HOSE,HI DPF DIFF, part number 37866RSXG01. It is specifically designed for HONDA vehicles to accurately measure the differential pressure across the Diesel Particulate Filter (DPF). Proper functioning of this hose is critical for the DPF system. It allows the engine control module (ECM) to monitor soot buildup and initiate regeneration cycles when necessary. A damaged or clogged hose can lead to inaccurate readings, potentially causing the DPF to fail or the vehicle to enter limp mode. Crafted from durable materials, this hose is built to withstand the harsh conditions under the hood, including high temperatures and exposure to exhaust gases. Replacing a faulty hose with this OEM part ensures the integrity of your DPF system and helps maintain your HONDA's emissions compliance and performance.
