Signs Indicate a Malfunctioning ICP Sensor in 6.0 Powerstroke Engines – 9 Symptoms

If your 6.0 Powerstroke engine powered vehicle has a malfunctioning injection control pressure (ICP) sensor, you will notice poor fuel efficiency, reduced engine performance, stalling, rough idling, engine misfiring, and other symptoms.

When the pressure of the fuel injection in the cylinders is not being regulated properly by the ICP, that is when you can understand that there are some issues.

Detecting these symptoms and addressing them as soon as possible will protect other engine parts from going bad. This article will also cover common causes for an ICP sensor to malfunction so that you can prevent this issue from happening in future.

At a Glance:

SymptomsProblem Sources
Poor Fuel Efficiency and Decrease in PerformanceIPR detects an incorrect fuel reading due to faulty ICP sensor.
Struggling to StartPower control module reports the faulty ICP sensor as a system failure.
Rough IdlingA bad ICP sensor doesn’t let the car stay in a smooth idle state.
Illuminated Engine Warning LightEngine not receiving enough fuel as the ICP sensor does not work.
StallingDue to low fuel pressure, the engine does not receive enough fuel.
Locked BrakesBrake lock issues are rare, but it can happen when the ICP sensor malfunctions.
Engine MisfiresA faulty ICP sensor causes engine issues because it reads an incorrect value of air-fuel flow.
Error Codes on ScreenWhen monitoring for issues, error codes appear that are linked to malfunctioning ICP sensor.
Decrease in AccelerationIncorrect fuel level reading so fuel consumption is decreased as a result, the car does not receive enough energy to accelerate.

9 Symptoms of 6.0 Powerstroke ICP Sensor Failure

If you notice multiple symptoms from the following list, you can take that as a warning sign, and take initiative to fix the issue.

1. Poor Fuel Efficiency and Decrease in Performance

If you start noticing that your vehicle is unable to accelerate when you set foot on the pedal, then it is a major sign. A defective ICP sensor is going to cause your vehicle to use up excessive fuel and it will struggle to pick up speed.

This happens because, if the ICP is unresponsive, IPR relies on a pre-programmed fuel schedule without a correct reading of the fuel system. Since it does not know the current fuel level due to a faulty sensor, you’ll notice poor fuel mileage.

2. Struggling to Start

This is a common sign of a bad ICP sensor where the engine starts cranking when you turn it on and sometimes, it fails to start.

As the engine’s power control module reports the faulty ICP sensor as a system failure, it will not let the engine start without receiving the minimum acceptable performance from the ICP sensor.

3. Rough Idling

When the ICP sensor malfunctions, it will give inaccurate readings. Also, the vehicle won’t idle smoothly when you withdraw the throttle. In worst case scenario, it won’t return to normal state even when you let up on the fuel. You may also notice inconsistent RPM.

4. Illuminated Engine Warning Light

One of the last signs you would expect your vehicle to show is the little orange light on the dashboard. When the ICP sensor fails to work properly, it results in the “Check Engine” light turning on.

If the ICP sensor is not faulty, then there might be other issues with the engine.

5. Stalling

When the car starts to offer less power on pull-off like before and the engine beings to stall, it suggests that the ICP sensor is faulty.

A bad ICP sensor is going to struggle to idle or start to stall abnormally. This is because, usually, the Ford truck fuel system requires an oil pressure of 500 PSI at least to start and due to wrong signals, the engine mismanages itself.

6. Locked Brakes

Locked brakes are one of the worst symptoms of a faulty ICP sensor. Even though this has happened very rarely, it is extremely dangerous on the highway.

If the ICP sensors are not the reason for brake lock issues, then there might be other underlying problems with the vehicle.

7. Engine Misfires

A bad ICP sensor is going to affect the air-fuel ratio which is important for maintaining a smoothly running engine. Since the ICP sensor cannot manage that properly, the engine starts to misfire and cause damage to the parts.

In simpler words, due to a faulty ICP sensor, there is going to be a lack of acceptable engine performance.

8. Error Codes on Screen

If you get your 6.0 Powerstroke monitored for issues, there were a bunch of error codes on the screen if the ICP sensor is not working.

Codes such as P2285, P2286, and P2287 are the codes that will appear and all of them have their individual meanings, leading to the main issue.

Diagnostic Trouble CodeMeaning
P2285Low ICP sensor circuit
P2286High ICP sensor circuit
P2287Intermittent ICP sensor circuit

9. Decrease in Acceleration

As the ICP sensor is not working correctly, it is going to give the wrong reading of fuel level. Due to this, the fuel consumption is not efficient so the vehicle loses a lot of power. So, when you want to accelerate the car, it will not receive enough energy from the fuel system.

Causes of the ICP Sensor Failure in 6.0 Powerstroke

The primary causes of the 6.0 Powerstroke ICP sensor failure are –

  1. Lack of regular engine maintenance
  2. Excessive power usage
  3. Frequent engine overheating
  4. Loose connections within the system
  5. Ignoring the signs of distresses from the vehicle
  6. Driving the vehicle too roughly on a regular basis

How to Test a 6.0 Powerstroke ICP Sensor

  1. Attach the pins of a multimeter to the top of the ICP sensor you think might be faulty.
  2. If the multimeter starts to show codes we mentioned above, then it means the sensor is malfunctioning.
  3. Take a new ICP sensor and attach the pins at the top.
  4. The multimeter is not going to show any readings meaning that the sensor is working.

What to Do When Negative ICP Sensor Symptoms Appear in 6.0 Powerstroke

Here’re several steps you can take If you notice that the ICP sensor of your vehicle is showing issues –

  1. Take the vehicle to the nearest car maintenance shop as soon as possible.
  2. Check for any irregularities within the engine compartment connections.
  3. Within the parts, look for signs of oil leakages on the sensor.
  4. Verify using a monitor to check if the sensor’s voltage and pressure are giving the correct reading.
  5. Disconnect the sensor to see how the engine reacts. The PCM screen will display the oil flow information.

What is the Cost of Replacing an ICP Sensor for a 6.0 Powerstroke?

The 6.0 Powerstroke ICP sensor cannot be fixed, so you have to replace the part entirely. It is going to cost somewhere between $140 to $220 and the labor cost would be $70 to $150, depending on your area.

If you need a pigtail connector, then it will cost an additional $15 to $60. So, the total cost of replacing an ICP sensor is going to be within the range of $225 to $430.

However, if other materials are needed while carrying out the task, then the total cost might go higher.


What happens when the ICP sensor fails?

A failed ICP sensor is going to weaken the performance of your pickup truck. The vehicle is going to stall and sputter. Mostly, there are going to be a lot of engine misfires and the truck will often fail to start.

Where can I find the ICP sensor on the 6.0 Powerstroke?

The ICP sensor is located in the Powerstroke’s upper and lower parts within the middle. To gain access to the ICP sensor, you have to remove the heat shield of the pipe or the FICM.

What is normal ICP pressure?

The normal ICP pressure is going to be within 5 to 15 mm Hg.

How serious is a 6.0 Powerstroke bad ICP sensor issue?

At first, the issue is not that serious and the vehicle is going to respond normally. But if the problem is not fixed, you will eventually notice poor mileage, engine misfiring, stalling, engine not being able to start, poor acceleration performance, etc.

Can you drive even when the ICP sensor is bad?

Yes, you can still drive the vehicle when the ICP sensor is bad, as long as it is not heavily affecting the engine, meaning doesn’t stall the engine.
