Are you experiencing decreased power or acceleration from your 6.0 Powerstroke? Is your engine running rough?
Your issue may be related to a faulty injector circuit.
This article will discuss the causes, symptoms, and solutions to P0267 6.0 Powerstroke. We will also discuss what the code says about your vehicle, how to avoid it, and other related codes you might encounter later.
So What Is P0267 6.0 Powerstroke
The Diagnostic Trouble Code (DTC) P0267 6.0 Powerstroke stands for “Cylinder Number 3 Injector Circuit Low”. This means that the vehicle’s Engine Control Module (ECM) has detected a low voltage with the injector circuit for the third cylinder on the firing order.
The ECM is like the brain of the engine. It is a computerized device that controls the various aspects of the engine by receiving and sending signals from various components, including the Fuel Injection Control Module (FICM).
The FICM is tasked with managing the fuel injection system by controlling the voltage sent to the fuel injectors. The voltage from the FICM determines when and how much fuel is delivered to the engine.
So, when DTC P0267 pops up in your diagnostic tool, it means that the ECM has received signals from the FICM that the injector on cylinder number 3 (based on firing order) is experiencing low voltage and hence is not performing optimally.
Symptoms Associated With P0267 Code 6.0 Powerstroke.
Some of the symptoms associated with this particular DTC include:
Engine light:
The most obvious symptom of an issue with the engine’s performance is the check engine light turning on.
Rough running:
This describes a case where the engine is not running smoothly and steadily. A vehicle experiencing rough running is shaky, jerking, and may produce an unusual sound.
Poor engine performance:
For an engine to run, it needs the right mixture of fuel and air, and thus when the engine is not getting the right amount of fuel- due to injector issues – it cannot perform optimally.
Decreased fuel efficiency:
As the injector is tasked with fuel flow in the engine, having an injector problem may affect the amount of fuel being channeled to the engine resulting in Low Miles-Per-Gallon (MPG). Low MPG means the automobile is getting fewer miles out of a gallon than it should; in other words, poor fuel efficiency.
Low power output:
Engines with fuel injection problems are characterized by low power output, which can be noticed when carrying heavy loads, accelerating, or driving uphill.
Misfire:
Sometimes, the lack of optimal performance in the #3 Cylinder will result in a misfire of the engine. The misfire occurs because the fuel-air mixture is not ignited correctly, which in our case, has been caused by cylinder #3 not functioning optimally.
Causes Of P0267
In a Ford, P0267 may be caused by:
- Loose connections between the injector and injector circuit
- Damages or shorted wires that connect the injector to the injector circuit
- Faulty injectors: If the injector is damaged, it may send the wrong signals triggering the code.
- Faulty FICM: If the FICM is faulty, it may distort the signals transmitted to the ECM, triggering the code.
6 Steps To Troubleshoot DTC P0267 6.0 Powerstroke
- Use an OBD-II scanner to retrieve the specific DTC (P0267) together with the associated freeze data to provide the necessary information to identify the problem.
- Open the hood and visually inspect the engine and associated components for any signs of damage, wear or tear.
- Inspect the wiring and connections of the injector circuit for loose or damaged wires. This includes inspecting harnesses for damages that might cause electrical shorting resulting in abnormal voltage transmission.
- Check the resistance of the injector circuit using a multimeter. This will help to determine if there is an open or short in the circuit. Compare the different values to the manufacturer’s recommendations.
- Check Cylinder #3 injector operation. Conduct a buzz test to determine the status of this particular injector. A buzz test involves applying a high voltage to the injector and noting whether this particular injector produces a buzzing sound. Properly functioning injectors have a steady buzz sound.
- Use an OBDII scan kit to check the voltage range provided by the FICM. For a properly functioning FICM, the voltage range should be between 46-48 Volts. Anything below or above this range indicates that the FICM has a problem.
Where Is The Injector Circuit Located In the 6.0 Powerstroke Engine
The injector circuit for a 6.0 Powerstroke engine is located within the engine. Specifically, the injector circuit is attached to the fuel injector control module (FICM), which is typically located on the driver’s side of the engine, near the top of the engine valley.
Fixing P0267 Code 6.0 Powerstroke
- Ensure there are no loose connections in the injector circuit.
- Replacing damaged wires, including those with damaged harnesses.
- Replace the injector if it fails the resistance test and the buzz test.
- Replacing the FICM if the voltage results are not within the recommended range (46-48 volts).
Other Models With P0267
Ford P0267 code is mostly associated with the 6.0 Powerstroke engine for Ford vehicles manufactured between 2003 – 2007. Besides Ford vehicles, Hyundai vehicles also experience the P0267 code with almost identical causes, symptoms, diagnosis, and repair.
How To Avoid P0267 Code On 6.0 Powerstroke
- Regular servicing of the vehicle by a professional mechanic
- Regular visual inspection of the vehicle to identify damaged parts or components
- Regular inspection of wirings and connections to ensure there are no loose or damaged wires, in addition to checking exposed wires that might cause electrical shorting.
- Keeping an eye on the vehicle’s performance while on the road to note any changes in performance. Changes in performance are usually a good sign of a problem with the vehicle.
Costs Associated With P0267 6.0 Powerstroke
Depending on the cause that triggers the OBDII code, the costs associated with the problem vary.
If the cause that triggers the code is loosened wires, you will not incur any financial costs in fixing the problem.
However, if fixing the problem involves replacing a component, the financial costs will involve purchasing the component.
Additionally, if you decide to involve a professional in the matter, he/she/they will determine the cost. Involving a professional in the matter is recommended if you have little to no knowledge of the inner workings of a vehicle.
Related Codes
Some of the other codes related to the injector on Cylinder #3 include the following:
- P0268
- P0269
- P0303
Is It Safe Driving With A P0267 DTC
It is not recommended to drive with a DTC P0267. This is because an issue with an injector may result in an engine misfire which causes additional damage to the engine.
Conclusion
In conclusion, P0267 (Cylinder Number 3 Injector Circuit Low) is a common issue on 6.0 Powerstroke diesel engines. It can cause a range of problems, from rough running to poor engine performance and engine misfires. It is important to diagnose and fix this issue as soon as possible, to avoid further damage to the engine and to ensure good performance and fuel efficiency.
