7.3 Powerstroke ICP Sensor Location

ICP sensors are present in 7.3 and 6.0L Power Stroke engines with high-pressure oil systems, which employ oil pressure to pressurize fuel in each injector’s body. The PCM uses the injector pressure regulator to regulate oil pressure based on information from the ICP sensor.

This sensor measures the real oil pressure in the high-pressure system. This sensor, the ICP, is an analog sensor that outputs an analog voltage between zero to five volts. If you’re experiencing some problem and want to know the 7.3 Powerstroke ICP sensor location, read on.

Where Is The ICP Sensor Located On A 7.3 Diesel?

The ICP sensor 7.3 location is beside the high-pressure oil pump, placed on the driver’s side cylinder head, near the front of the engine.

What Happens If You Unplug Your ICP Sensor?

Unplugging the sensor also unplugs the sensor’s ICP input, which replaces the PCM with a “best guess” scenario. The ICP sensor will function normally only if you estimate it right; else, it won’t operate.

Can I Run My 7.3 With ICP Unplugged?

Yes. Although you can operate the 7.3L without the ICP sensor connected, you’ll be gazing at the SES/CE light all of the time.

How Do You Check The ICP Sensor On A 7.3 PowerStroke?

The pigtail from a 7.3 ICP sensor may be quickly removed by lifting the plastic clip on the cabling connection. An ICP sensor has failed if there is oil on the plug receptacle, the sensor’s leads, or the pigtail connection.

The oil rail pressure is measured by the ICP sensor 7.3. Your ICP sensor’s internal components and plastic electrical connection housing are subjected to a lot of stress over time because of all that oil pressure.

This is going to collapse after a few hundred thousand kilometers. When this happens, the oil will interfere with the sensor’s capacity to transmit electrical impulses, resulting in inaccurate results.

The 7.3 ICP pigtail must be disconnected while the engine is running. As a result, while the PCM is idle, the ICP is set at 725 PSI. When compared to the factory default of 500-550 PSI. Idle performance should improve noticeably after your ICP is unplugged.

Your 7.3 ICP is most likely currently operating on this default level if you don’t see a change in performance The problem might be with your ICP.

Note: Don’t disconnect it while it is still operating. Start the vehicle once you have unplugged it. A defective ICP sensor will cause the computer to perform better than it did when it was hooked in.

With a diagnostic tool that is compatible with Powerstroke, you can keep track of ICP, voltage, and IPR duty cycle. Generic OBDII scanners will not function on these vehicles.

Replacing ICP Sensor On 7.3 Powerstroke

However, although the techniques and position of the sensor are the same for all 7.3L Power Stroke diesel engines, the engines from 1999 to 2003 may have a somewhat different appearance from the engines from 1994 to 1997 generation engines.

Replacing the ICP sensor is not a difficult procedure, albeit the older International design sensors are more difficult to remove than the newer Ford style sensors, which are easier to remove.

It is unlikely that the connector and pigtail will need to be replaced if the ICP sensor harness is in good condition, so cleaning the connector thoroughly with an aerosol “electronic cleaner” solvent from CRC is a good precaution. This solvent will not damage the connectors or seals and is very effective at getting rid of oil from connectors.

  1. Disconnect the negative battery wires from both batteries.
  2. The high-pressure oil pump and the ICP sensor are located at the front of the engine, on the driver’s side of the cylinder head.
  3. The electrical connection should be removed from the ICP sensor by loosening the retaining clip and lifting the connector upwards away from the sensor.
  4. In this ICP sensor, you’ll observe that an accumulation of oil has accumulated in the sensor connection, indicating that the sensor should be changed.
  5. Sensors are classified into two categories. This is the original International ICP sensor, which has a circular body and a 5/8-inch connector “It has an incorporated nut at the bottom. It may be removed using a curved 5/8″ open-end wrench or a 5/8” crows foot, which are both available on Amazon.
  6. The Ford replacement sensor features a 1-1/16-inch threaded hole “sensor with a hex head built into the body of the sensor It may be removed and reinstalled with a 1-1/16 inch wrench or deep socket. The two categories may be used in conjunction with one another.
  7. Disconnect the ICP sensor from the high-pressure oil galley in the cylinder head and store it somewhere safe. Once the sensor has been removed, take care not to allow any dirt or debris to enter the channel.
  8. Clean engine oil should be used to coat the o-ring of the replacement sensor before it is installed in the vehicle. Reduce the snugness of the fit, but do not overtighten.
  9. A variety of tools may be used to install the sensor, including a 1-1/16-inch sensor socket.
  10. Replacement of the ICP connection pigtail is necessary if it is cracked, has exposed wires, or is otherwise damaged. Pigtail replacement is expensive, but it doesn’t have to be done every time a sensor is changed.
  11. Installing the ICP sensor’s connection after adding dielectric lubricant to the terminals and testing for appropriate functioning if the pigtail is not replaced.
  12. Removing the wire loom will reveal the pigtail and allow you to work in a more manageable area while changing the connection.
  13. Wires should be cut from the ICP sensor’s connecting harness such that around 1/4″ of copper may be seen.
  14. Replace the pigtail and follow the same procedure. Only the faulty section of wire has to be removed; avoid cutting the harness’s cables too deeply. There was an old pigtail that had to be cut off around halfway between its connection and the main harness.
  15. Three butt splices and heat shrink tubing are included with the Ford replacement pigtail. Splice the pigtail into the current harness after applying heat shrink to the wires.
  16. To ensure that no splice is visible once the tubing has been crimped, wrap the ends with heat shrink tubing and fix using a heat gun.
  17. The sensor pigtail’s wire loom must be reinstalled and secured. Additional flexible wire loom was added to the pigtail to ensure that it was completely shielded.
  18. Before re-installing the connection and testing it, use a little quantity of dielectric grease on the connector’s terminals.

Final Thoughts

The 7.3 Powerstroke ICP sensor is located on the driver’s side of the engine, near the high-pressure oil pump. Be sure to consult a professional or reference a guide before attempting to replace the ICP sensor.

Replacement of the ICP connection pigtail is necessary if it is cracked, has exposed wires, or is otherwise damaged. Pigtail replacement is expensive, but it doesn’t have to be done every time a sensor is changed.
