Engineered specifically for late 2004 through 2007 Ford F-250, F-350, F-450, F-550 Super Duty and Excursion trucks equipped with the 6.0L Powerstroke diesel engine (built from November 4, 2004, and later), the Genuine Ford Exhaust Back Pressure (EBP) Sensor Tube (5C3Z-9D477-A) provides reliable factory replacement for aging or restricted metal lines. The EBP sensor tube is responsible for routing exhaust gases to the backpressure sensor, allowing the Powertrain Control Module (PCM) to calculate turbocharger VGT geometry and EGR operation. Over time, heavy soot accumulation and carbon buildup can completely clog this small-diameter tube, leading to erratic turbo response, sluggish throttle performance, and diagnostic trouble codes (such as P0470, P0471, or P0472).

Because aftermarket or poorly bent replica tubes frequently crack under high engine vibration or fail to align properly with factory exhaust manifold fittings, utilizing a genuine Ford OEM part ensures a stress-free, exact-fit installation. Manufactured to rigorous factory material standards, this direct-replacement tube maintains proper wall thickness to withstand high exhaust heat cycles without pinhole fatigue or leaking.

Key Features & Benefits

• Genuine Ford OEM Component: Designed and manufactured by Ford Motor Company to guarantee exact factory fit, form, and long-term durability.
• Restores Accurate EBP Readings: Clears carbon-plugged passages to provide the PCM with correct exhaust pressure data for optimal turbo boost control.
• Corrosion-Resistant Alloy Tubing: Built with heavy-duty metal alloys that resist extreme exhaust temperatures and under-hood thermal degradation.
• Precise Factory Routing: Pre-bent to exact OEM specifications, eliminating the fitment struggles and kinking common with universal aftermarket tubing.
• Resolves Persistent Diagnostic Codes: Effectively clears stubborn EBP sensor correlation and low-circuit codes (P0470–P0474).

Vehicle Fitment & Installation Notes

• Late 2004–2007 Ford F-250 / F-350 / F-450 / F-550 Super Duty – 6.0L Powerstroke Diesel (Engine build dates from 11/04/2004 through 2007)
• Late 2004–2005 Ford Excursion – 6.0L Powerstroke Diesel
• Fits Model Years: Late 2004, 2005, 2006, 2007
• Fitment Notice: Engineered strictly for late 2004–2007 models built on or after November 4, 2004. Does not fit early 2003 to mid-2004 production trucks, which require earlier part configurations. Verify your vehicle build date or existing tube layout before ordering.
• Installation Tip: Allow the exhaust manifold and turbo area to cool completely before servicing. Use a proper line wrench to avoid rounding the mounting fittings, and thoroughly clean out the exhaust manifold port fitting to ensure the new tube seats cleanly without carbon debris blockage.
