Reasons to Upgrade
-
The Injection Control Pressure (ICP) Sensor is one of the most important components in your 7.3 Powerstroke’s high-pressure oil system. When it begins to fail, you’ll notice hard starts, poor throttle response, erratic idle, or the dreaded no-start condition.
-
After testing and comparing sensors from dozens of suppliers, Sinister Diesel identified this version as the most accurate, consistent, and reliable unit available. Our testing showed tighter tolerance readings and the lowest failure rate in both bench and field evaluations.
-
Unlike many low-cost alternatives that suffer from signal drift or heat failure, the Sinister Diesel ICP Sensor maintains precise output even under prolonged exposure to engine heat and pressure.
-
It’s the only replacement we trust to install in our in-house 7.3 test trucks — because it performs flawlessly, mile after mile.
Product Description
The Sinister Diesel Injection Control Pressure (ICP) Sensor is the result of extensive testing and quality validation to ensure your 7.3L Powerstroke runs exactly as it should. This vital sensor communicates real-time oil pressure data to the PCM, allowing for accurate injector control, smooth idle, and strong throttle response.
When the factory sensor begins to fail, it can send erratic signals that lead to poor performance, surging, or a complete no-start. Our ICP sensor eliminates those issues with precision-calibrated internals that deliver consistent readings across all temperature and pressure ranges. Built to handle the extreme conditions of diesel operation, it offers superior longevity compared to OEM and aftermarket alternatives.
