AUTOKAY ICP Sensor for 6.0L Powerstroke 2004–2007 — Direct OEM-Fit Replacement, Single Unit

AUTOKAY Powerstroke 6.0 ICP sensor (1845428C92 / 4C3Z-9F838) measures fuel rail pressure and sends accurate readings to your 2004–2007 Ford Super Duty engine control system.

This direct-replacement intake control pressure (ICP) sensor is specified for the 6.0L Powerstroke diesel lineup in various Ford E-series and F-series models made between 2004 and 2007. It provides the signal your engine computer uses to manage fuel delivery and timing, and it’s supplied as a single unit to fit the original sensor mounting and electrical connector pattern. The part is built to match OEM fitment and restore proper pressure monitoring after failure or during an engine rebuild.

How will this ICP sensor fit my 2004–2007 Ford Powerstroke?

The AUTOKAY ICP sensor is designed to match original mounting points and electrical connectors for compatible Ford models, making installation straightforward for technicians and experienced DIYers. It is a direct replacement that aligns with the OEM form factor and connector layout.

• Compatible with 6.0L Powerstroke engines in Ford E-350, E-450, Excursion, and F-250 to F-750 models (2004–2007).
• OEM reference: 1845428C91 and 4C3Z-9F383-AB for cross-checking fitment.
• Includes one fuel pressure/ICP sensor per package for single-sensor replacements.
• Plug-and-play electrical connector designed to match factory wiring harness.

What symptoms does a failing ICP sensor cause and how does replacement help?

A worn or faulty ICP sensor can produce erratic pressure readings that lead to engine hesitation, rough idle, trouble codes, or limp-home mode. Replacing the sensor restores reliable pressure feedback to the engine control unit so fuel control logic can operate as intended.

• Reduces false pressure readings that trigger diagnostic trouble codes (DTCs).
• Helps stabilize idle and improve throttle response by restoring accurate input signals.
• Prevents unnecessary part swaps by addressing the sensor directly when it’s the cause.
• Useful when troubleshooting fuel system or injector control issues on 6.0L Powerstroke engines.

How difficult is installation and what tools or precautions are recommended?

Installation is moderate in difficulty and typically requires basic hand tools, safety precautions for working on a hot engine, and adherence to torque specifications. Individuals familiar with diesel engine service can replace the sensor in a short workshop session; seek professional help if wiring or access is restricted.

• Common tools: ratchet, appropriate sockets, and dielectric grease for connector protection.
• Allow the engine to cool before working near the rail or intake manifold to avoid burns.
• Inspect the wiring harness and connector for corrosion or damage before installing the new sensor.
• Clear codes after installation and test-run the engine to confirm proper operation.
