6.0 Powerstroke Bad ICP Sensor Symptoms: (6 Symptoms To Detect)

by

Is your engine causing misfires, and at times, your engine stops starting?

While there could be several issues contributing to these incidents, the most common culprit is a malfunctioning ICP sensor in the 6.0 Powerstroke engine.

In this article, we will delve into the symptoms of a defective ICP sensor in the 6.0 Powerstroke engine.

Signs Of A Bad 6.0 Powerstroke ICP Sensor

A faulty ICP sensor will manifest certain signs, though they may not conclusively point to a bad ICP sensor.

1. Misfires, Surging, or Stalling

If you experience misfires, surging, or stalling, particularly when coming to a complete stop, rough idling, surging, bucking, and stalling, these are clear indicators that you need to inspect your ICP sensor.

Additionally, when the ICP sensor goes bad, you’ll notice other specific symptoms.

6.0 Powerstroke Bad ICP Sensor Symptoms

In addition to the signs mentioned above, there are specific symptoms that signal trouble with your ICP sensor. When you encounter these symptoms, it’s imperative to check your ICP sensor and consider taking your vehicle to a service center. Continue reading to learn how to identify a bad ICP sensor in the 6.0 Powerstroke engine.

1. Starting Issues

Frequently, starting problems are associated with a faulty ICP sensor. When your ICP sensor malfunctions, your engine will struggle to start as it perceives a system failure. However, difficulties during startup may also stem from other issues.

2. Engine Misfires

A primary symptom of a bad ICP sensor is engine misfires. Engine performance issues become apparent when your sensor is not functioning correctly. A damaged or defective sensor can disrupt the fuel mixture, leading to engine misfires.

3. Decrease In Power, Acceleration, And Fuel Economy

When your ICP sensor is malfunctioning, it can result in reduced power and acceleration. You may notice a significant loss of power, and attempting to accelerate quickly may not yield the expected results. Nevertheless, it’s crucial to note that similar symptoms can be attributed to other engine problems. Therefore, a proper diagnosis is essential.

4. Locked Brakes

In some instances, ICP sensor problems can lead to locked brakes. When the engine experiences issues due to a malfunctioning sensor, it may also affect the braking system. While such occurrences are relatively rare, they can be unsettling when they do happen.

5. Dashboard Warning Lights

An unmistakable symptom is the illumination of warning lights on your dashboard, signaling you to check the engine. The Check Engine Light will activate if the computer detects an issue with the injector control pressure sensor or its circuit. However, it’s important to note that a lit Check Engine Light can result from various other problems. Therefore, it is strongly advisable to have the computer checked for trouble codes.

6. Error Codes On The Display

You might encounter various error codes, such as P2285, displayed on your computer screen, which will point you toward a faulty ICP sensor. If you come across any of these codes, be sure to inspect the injector control pressure sensor for any potential issues.

In conclusion, a malfunctioning ICP sensor in the 6.0 Powerstroke engine can manifest in various ways, affecting engine performance and reliability. Identifying and addressing these symptoms promptly is crucial to ensure the smooth operation of your vehicle. If you suspect a problem with your ICP sensor, it is advisable to seek professional assistance to diagnose and resolve the issue effectively.

What To Do When You Detect A Bad ICP Sensor in a 6.0 Powerstroke?

When you observe the aforementioned symptoms, it’s time for a diagnosis.

1. Inspect for Oil Leaks

Begin by examining the connections inside the engine housing. If you notice any oil leaking from the ICP, try to locate the source of the leak.

2. Test the Sensor

Even if there are no apparent leaks, the sensor may still be the issue. Start the engine and unplug the pigtail of the ICP. Observe whether the engine’s idle improves or not. If your car is equipped with a scanner, you can monitor live data changes on the screen.

3. Unplug the ICP Sensor

Next, unplug the ICP sensor and observe how the engine performs. You should notice that the Powertrain Control Module (PCM) provides data on oil flow. If the PCM does not receive data from the ICP sensor, it will default to an ICP value of approximately 700. If the sensor is functioning correctly, the idle speed should be around 500 RPM.

4. Further Diagnosis

If you still have doubts about the ICP, proceed with the following steps:

  • Use a monitoring device to check the ICP pressure and voltage to ensure accuracy.
  • Examine the entire harness between the ICP and the PCM for any issues or anomalies and rectify them.
  • Check the integrity of the reference, signal, and return pins allocated to the ICP on the PCM connection.
  • Ensure that the PCM and the ICP pigtail are properly connected via the harness.

If your car doesn’t start when you turn on the ignition, verify that you have a solid ground and reference at the pigtail using a meter or scope. Check for electrical noise and reconnect the ICP. The engine should start now. While using a scope, monitor both the reference and signal for any dropouts.

If none of the above steps resolve the issue, consider cutting the pigtail and disconnecting the ICP, allowing the PCM to take control temporarily. Finally, contact a qualified mechanic and invest in a new ICP sensor.

Is Replacing an ICP Sensor on a 6.0 Powerstroke Typically Expensive?

The replacement cost of an ICP sensor is not exorbitant. However, the expense includes labor costs and, in some cases, additional costs.

  • The ICP sensor typically costs around $140-$220.
  • Labor costs range from $70-$150.
  • A pigtail connector, if needed, can cost $15-$60.

This totals approximately $225-$430. Keep in mind that prices may vary depending on where you purchase the parts and have the work done.

How Often Should You Inspect or Service an ICP Sensor on a 6.0 Powerstroke?

Routine inspections of the ICP sensor are not always necessary. While ICP failures are relatively uncommon in recent times, some sensors have been found to be faulty.

Even if the sensor remains functional, it’s advisable to include it in your regular maintenance checks, just like other vehicle components. When inspecting the engine, pay attention to the pigtail and ICP connections. If you detect oil leaks or any of the symptoms mentioned earlier, take your vehicle to a service center promptly.

Alternatively, you can adhere to the planned service intervals for the entire engine and vehicle, which can help you save on expenses.

Final Thoughts

The ICP sensor plays a vital role in maintaining oil injections in the engine, and a malfunctioning sensor can lead to various driving difficulties.

For an optimal driving experience, it’s essential to take good care of your vehicle and service it regularly. If you encounter any of the symptoms mentioned in this article, promptly diagnose the ICP sensor and take appropriate measures, including repairs or replacement, to ensure your vehicle’s continued smooth operation.
