Injection Control Pressure (ICP) Sensor for 1994–2003 Navistar T444E Engine

Keep your diesel engine running at peak performance with this direct-fit Injection Control Pressure (ICP) Sensor, engineered as a precise replacement for the Alliant Power AP63418 and OEM part number 1807329C92. Built from oxidized iron for outstanding corrosion and oxidation resistance, this sensor continuously monitors hydraulic oil pressure and relays critical data to the PCM — helping regulate fuel injector operation through the Injection Pressure Regulator (IPR) and alerting the system when oil pressure drops below safe operating thresholds.

Replacement OEM Part Numbers

This sensor is compatible with and replaces the following part numbers: 1807329C92, 1807329C91, 1807329, ICP102, F6TZ-9F838-A, F4TZ-9F838-A, F6TZ9F838A, F4TZ9F838A, CM5227, 112841, 1807329CP2, 450585, 1824216C2.

Key Features

Corrosion-Resistant Construction: Made from oxidized iron to withstand harsh engine environments and resist oxidation over time.
Accurate Pressure Monitoring: Continuously tracks hydraulic oil pressure and communicates with the PCM to ensure proper fuel injector pressurization via the IPR.
Protects Engine Integrity: Helps safeguard the engine by detecting low oil pressure conditions before they escalate.
Direct OEM Replacement: Drop-in fitment designed to restore your vehicle to proper factory operation quickly and reliably.
Easy DIY Installation: Simple swap-out process — remove the old sensor, install the new one, and you're back on the road. No special tools required for most applications.
100% Quality Tested: Every unit undergoes strict quality inspection before shipping to ensure reliable, long-lasting performance.

Frequently Asked Questions

Q: What does the Injection Control Pressure (ICP) Sensor do on a T444E engine?

A: The ICP sensor monitors the hydraulic oil pressure in the high-pressure oil system of the Navistar T444E (7.3L Power Stroke) engine. It sends this data to the Powertrain Control Module (PCM), which uses it to regulate the Injection Pressure Regulator (IPR) and ensure fuel injectors receive the correct operating pressure for efficient combustion.

Q: How do I know if my ICP sensor needs replacing?

A: Common signs of a failing ICP sensor include hard starting, rough idle, engine misfires, poor throttle response, or a check engine light. If your 1994–2003 Navistar T444E is showing any of these symptoms, testing or replacing the ICP sensor is a recommended first diagnostic step.

Q: Is this ICP sensor compatible with my Ford 7.3L Power Stroke truck?

A: Yes. The Navistar T444E is the same engine found in Ford F-250, F-350, F-450, and E-Series vans equipped with the 7.3L Power Stroke diesel from 1994 to 2003. This sensor is a direct-fit replacement for those applications, provided the connector matches the images shown.

Q: Does this sensor come with a warranty or satisfaction guarantee?

A: Yes. Every unit is 100% quality tested before shipping. If you experience any issues with your ICP sensor, contact the seller for a replacement or full refund — support responses are provided within 12 working hours.
