Reasons to Upgrade
-
The Injection Control Pressure (ICP) Sensor is one of the most critical parts of your 6.0 Powerstroke’s fuel injection system, providing the PCM with vital oil pressure data that controls injector operation.
-
The factory sensors are no longer available from Ford, and many aftermarket replacements fall short — producing erratic readings, early signal loss, or outright failure under heat and vibration.
-
That’s why Sinister Diesel invested heavily in testing dozens of ICP sensor manufacturers to find the one that performed closest to OEM standards. We logged thousands of hours of data on heat cycling, signal accuracy, and failure patterns — and this sensor consistently ranked #1 for reliability and precision.
-
This is the sensor we use in our own test trucks and customer builds because it delivers consistent performance, tight signal calibration, and long service life — without the failures we’ve seen from cheaper alternatives.
Product Description
The Sinister Diesel Injection Control Pressure (ICP) Sensor is a precision-engineered replacement for the early-build 2003–2004 6.0L Powerstroke. It provides accurate oil pressure feedback to the PCM, ensuring proper injector control and smooth engine operation.
A failing ICP sensor is one of the most common causes of rough idle, surging, hesitation, or no-start issues in early 6.0L Powerstroke engines. This replacement is built to exceed OEM reliability standards and is tested to deliver consistent signal output even under the extreme conditions of diesel operation.
Sinister Diesel sourced, tested, and validated dozens of sensors from multiple manufacturers to find this version — the most accurate and durable available today. The result is an ICP sensor you can install with total confidence, knowing it will perform flawlessly in your truck for years to come.
