If you’re experiencing any of these symptoms and have noticed a check engine light on your dashboard, it’s time to tackle the P0264 trouble code. In this article, we will uncover the truth behind the Cylinder 2 Injector Circuit Error and walk you through the steps to diagnose and fix this DTC p0264 on your 6.0 Powerstroke engine.

Let us get started and put an end to your P0264 troubles!

Truth Behind DTC P0264 on a 6.0 Powerstroke: What The He** Does It Mean?

The P0264 6.0 Powerstroke indicates a problem with the injector circuit on cylinder number 2 on the firing order. Specifically, the code highlights that the Fuel Injection Control Module (FICM) has detected a low voltage on the injector circuit for the particular cylinder.

The Fuel Injection Control Module (FICM) controls the fuel injectors It sends power to the injectors to spray fuel into the engine. It works with other vehicle components to ensure the engine receives the right amounts of fuel at the right time for smooth running.

FICM is powered by the battery and uses a voltage regulator to keep the voltage at the right level. If the voltage level fluctuates or operates beyond the required set parameters, it sends signals such as the DTC P0264.

Where Do You Find The Injector Circuit For A 6.0 Powerstroke Engine? 

The injector circuit is attached to the fuel injector control module (FICM). This module is usually located on the driver’s side of the engine, near the top of the engine valley.

Causes Of P0264 On 6.0 Powerstroke

This DTC p0264 ford can be caused by a variety of issues, including:

Clogged or partially clogged injector:

If it becomes clogged or partially clogged with debris, it can prevent fuel from flowing properly, resulting in poor engine performance and triggering the P0264 code.

Damaged injector:

A damaged injector can also prevent fuel from flowing properly. Injectors can become damaged due to wear and tear over time or as a result of exposure to contaminants in the fuel system.

Voltage output issues or damaged FICM:

The FICM sends power to the injectors. If there are voltage output issues (low voltage) with the FICM, it can cause the injectors to malfunction. Also, damaged FICM causes malfunction of the injectors.

Loose or damaged injector connector and wiring:

The connector that connects the injector to the FICM can become loose or damaged over time, causing a loss of power to the injector.

Symptoms to look out for when faced with DTC P0264 Ford.

P0264 6.0 Powerstroke can manifest in a number of symptoms, such as:

Check Engine Light

This is the most prominent symptom that something is wrong with the vehicle. In such cases, a diagnostic tool provides a specific code to pinpoint the cause of the check engine light, such as DTC P0264.

Poor engine performance

A faulty injector circuit means the engine is not receiving the optimum fuel at the right time. This can affect the engine’s performance, resulting in decreased power or acceleration.

Decreased fuel efficiency

When there is a problem with an injector, more fuel may be needed to achieve the optimum level of performance, resulting in lower fuel economy.

Rough idling

When there is trouble with an injector, the engine may not be able to maintain a smooth idle, leading to vibrations and uneven running.

Regular Servicing of Vehicle

Regular servicing of the vehicle by a professional mechanic can help identify and prevent potential problems before they occur. This includes checking the FICM and replacing any worn-out or damaged parts.

Inspecting Injector Circuit Connections

Regularly inspecting the connections and wiring for the injector circuit can help identify any loose or damaged components, thus helping avoid injector problems that may cause P0264.

Flushing Injectors

Regular flushing of injectors to avoid clogging. Clogged or partially clogged injectors can cause the P0264 code. Regularly flushing (cleaning) the injectors can help prevent clogs and ensure proper fuel flow to the engine.

Monitoring Vehicle Performance

Keeping an eye on the vehicle’s performance and noting any changes, such as poor engine performance, can help identify potential problems early on and prevent the P0264 code from being triggered.

Diagnosing P0264 6.0 Powerstroke

Here are some steps that can help in diagnosing DTC P0264:

  1. Obtain the DTC using a Diagnostic Scanning Tool as well as the corresponding freeze data.
  2. Inspect the engine and its related parts for any indication of wear, tear, or damage by looking under your vehicle’s hood.
  3. Take a look at the wiring and connections of the injector circuit. Look out for any loose or damaged wires. You should also check the harnesses for damages that might cause electrical shorting.
  4. Using a multimeter, check the injector circuit resistance for Cylinder #2. First, turn off the engine and disconnect the electrical connector from the injector. Then, set the multimeter to the Ohms setting and place the probes on the injector terminals. The resistance reading should be within the manufacturer’s specifications.  
  5. Determine the functionality of the Cylinder #2 Injector. A buzz test is the most popular injector test done by providing a high voltage to the injector and listening for a buzzing sound (ensure the area around you is quiet in order to hear the sound). A well-functioning injector will produce a consistent sound.
  6. Check the voltage supply to the FICM to ensure that it is within the specified range. You can use the OBD-II Scan Kit for this test. The voltage range for a properly functioning 6.0 Powerstroke FICM should be between 46-48 volts. 
  7. Check the FICM to see if it is damaged or malfunctioning.

Cost Of Diagnosing The P0264 6.0 Powerstroke

The cost of diagnosing the error code can vary.

  • If you have a diagnostic tool, there is no cost to incur during diagnosis, as you can plug the device into the module and get the exact error code.
  • If you do not possess the diagnostic tool, then the cost can include that of purchasing the diagnostic tool or the service charge by a professional mechanic to diagnose the problem.

Kindly Note: the cost of diagnosing is separate from the cost of repairing the problem.

How To Fix P0264 6.0 Powerstroke On Your Ford

Recommended solutions include:

Check the wiring and connections for the injector circuit:

Looking for any loose, damaged, or corroded connections. If any are found, they should be replaced or repaired as necessary to ensure proper power flow to the injector.

Flushing/cleaning the injectors

If the injectors are clogged or partially clogged, flushing or cleaning them can help to restore proper fuel flow. The most recommended cleaning fluids include the Sea Foam IC5 Fuel Injector Cleaner and the Hot Shot Secret.

Replacing a damaged injector:

If the injector is found to be damaged, it should be replaced to restore proper fuel flow and prevent the P0264 code from being triggered.

Replacing the FICM:

If the FICM is damaged or malfunctioning, it should be replaced to restore proper power flow to the injectors.

Common Mistakes During The Diagnosis Process Of DTC P0264 On 6.0 Powerstroke

Diagnosing the P0264 error code on a 6.0 Powerstroke engine can be complex and requires proper diagnosis to ensure that the correct solution is applied. Unfortunately, some common mistakes can be made during the diagnosis process, including:

Replacing the injector without testing it

It is essential to test the injector to determine if it is the actual cause of the problem before replacing it. This can save time and money by avoiding unnecessary replacement of parts. The most common injector test is the buzz test. 

Replacing the FICM without testing it

Test the FICM first to ensure it is the actual cause of the problem before opting for replacement.  

Replacing without checking loose connectors and wiring

Loose connectors and wiring are the common causes of the P0264 code. Replacing parts without checking the wiring and connections can lead to the same problem recurring, as the underlying issue needs to be addressed.

What Will Happen With Your 6.0 Powertstorke if Driving Without Fixing P0264

It is not recommended to drive a vehicle with the P0264 code present. 

The P0264 code indicates a problem with the fuel injector circuit on cylinder number 2, which can cause poor engine performance, lack of power, and decreased fuel efficiency. 

It is best to first inspect and repair the problem before driving.
