Ford 6.0 ICP Sensor Test

There are two main approaches to testing a 6.0 Powerstroke ICP sensor:

1. Using a Scan Tool:

This is the most accurate and recommended method. A scan tool allows you to monitor the live data coming from the ICP sensor, displaying the Injector Control Pressure (ICP) readings in PSI. You can then compare these readings to the expected values for your engine RPM and operating conditions. This will help identify if the sensor is sending incorrect pressure signals.

2. Basic Voltage Test (Less Accurate):

This method provides a preliminary check but isn’t as conclusive as a scan tool. Here’s what you’ll need:

• Multimeter
• (Optional) Back-probe pins (safer method than directly probing the sensor wires)

Steps:

1. Turn off the engine and consult a repair manual to locate the ICP sensor on your specific 6.0 Powerstroke model.
2. Disconnect the electrical connector from the ICP sensor.
3. Set your multimeter to DC voltage (DCV).
4. With the red probe, touch the power pin on the ICP sensor connector (usually the red wire). Caution: If not using back-probe pins, be very careful not to short any wires together.
5. Touch the black probe to a good ground (bare metal on the engine block).
6. Turn on the key to the “ON” position (without starting the engine).

A healthy ICP sensor should display a voltage reading between 0.4 volts and 0.5 volts with the key in the “ON” position (engine not running). This indicates the sensor is receiving power from the engine computer (ECU).

Remember:

• A voltage reading significantly lower or higher than this range suggests a potential issue with the sensor.
• However, a voltage within this range doesn’t necessarily guarantee a good sensor. It only confirms it’s receiving power.
• For a definitive diagnosis, using a scan tool to monitor live ICP pressure readings is highly recommended.

Additional Tips:

• Some resources recommend applying compressed air to the ICP sensor port while monitoring voltage to simulate pressure, but this method is not advised by all mechanics and requires additional tools and expertise.
• If you’re not comfortable performing these steps yourself, consult a qualified mechanic to diagnose your ICP sensor.
