Injector Control Pressure Sensor
Model: SensorMass20250317S1
Measuring range: Inside the engine
Style: Modern
Output Type: electrical signal
Description:
The Injector Control Pressure Sensor (ICP sensor) on a 7.3-liter Powerstroke diesel engine is a critical component of the high-pressure oil system. It monitors the oil pressure in the oil rails and sends this data to the Powertrain Control Module (PCM). The PCM uses this information to adjust the Injection Pressure Regulator (IPR), ensuring the correct oil pressure is delivered to the injectors for efficient fuel combustion.
Features
- Pressure Monitoring: Measures the oil pressure in the high-pressure oil system.
- Data Transmission: Sends real-time pressure readings to the PCM.
- Injector Control: Helps regulate the oil pressure needed to actuate the injectors.
Application
- Suitable for a 7.3-liter Powerstroke diesel engine.
Injection Control Pressure Sensor 7.3 Location
The ICP sensor is typically located on the driver’s side cylinder head, near the front of the engine compartment, close to the High-Pressure Oil Pump (HPOP).

How do I know if my 7.3 ICP sensor is bad?
A failing Injector Control Pressure (ICP) sensor on a 7.3 Powerstroke diesel engine can cause several noticeable symptoms. Here are the most common signs:
1. Hard Starting: The engine may crank for an extended period or fail to start altogether.
2. Rough Idling: The engine might idle unevenly or vibrate excessively.
3. Loss of Power: You may notice reduced engine performance, especially during acceleration.
4. Stalling: The engine could stall unexpectedly, either while idling or driving.
5. Check Engine Light: Fault codes related to the ICP sensor (e.g., P1211, P1280) may appear.
6. Oil on the Sensor Connector: Oil saturation on the ICP sensor’s pigtail connector is a common indicator of failure.
What are the symptoms of a bad injector control pressure sensor?
A failing Injector Control Pressure (ICP) sensor can lead to various engine performance issues, especially in diesel engines like the 7.3 Powerstroke. Here are the most common symptoms:
1. Hard Starting or No Start: The engine may struggle to start or fail completely due to incorrect fuel injector pressure readings.
2. Rough Idling: An uneven or unstable idle may result from inconsistent oil pressure control.
3. Loss of Power: Reduced performance during acceleration or heavy loads is a frequent sign.
4. Stalling: The engine may stall unexpectedly, especially at low speeds or when idling.
5. Check Engine Light: The ECM often logs error codes related to the ICP sensor, such as P1211 (ICP pressure out of range) or P1280 (ICP circuit low).
6. Poor Fuel Economy: Incorrect injector control can lead to inefficient fuel usage.
7. Oil on the Sensor or Connector: A leaking ICP sensor may cause oil contamination on the sensor’s pigtail connector, which can affect its operation.
Where is the injection control pressure sensor located?
7.3 powerstroke injector control pressure sensor location: The Injection Control Pressure (ICP) Sensor is typically located on the driver’s side valve cover, near the front of the engine, in vehicles with a 7.3 Powerstroke engine. Specifically, it’s mounted close to the high-pressure oil pump (HPOP), which is part of the high-pressure oil system that drives the fuel injectors.
