When your engine’s Check Engine Light comes on and you’re confronted with a P0267 code, it’s time to investigate. This code signals a low voltage condition in the control circuit of your cylinder 3 fuel injector, which can lead to misfires, rough idling, and decreased power. You’re likely wondering what’s causing this issue and how to fix it. Is it a faulty fuel injector, wiring problem, or something more complex? Let’s plunge into the possible causes and solutions to get your engine running smoothly again.
Quick Navigation
Key Takeaways
- A P0267 code indicates low voltage in the control circuit of the fuel injector for cylinder 3, causing engine misfires or rough idling.
- Faulty wiring or connectors, malfunctioning fuel injectors, PCM issues, sensor problems, and electrical issues can cause a P0267 code.
- Symptoms include decreased power and acceleration, poor fuel efficiency, an illuminated Check Engine Light, and engine stalling or hesitation.
- Inspecting wiring and connectors, testing the fuel injector, and checking the powertrain control module can help fix the issue.
- Repair costs can vary widely, ranging from $150 to $500, depending on the specific cause and extent of repairs needed.
Code Description and Causes
When your vehicle’s onboard computer triggers a P0267 code, it indicates a low voltage condition in the control circuit of the fuel injector for cylinder 3 in the engine.
This means the fuel injector responsible for delivering the precise amount of fuel for combustion isn’t receiving the expected voltage. Faulty wiring or connectors in the injector control circuit can cause this issue, leading to improper fuel delivery and affecting engine performance.
Malfunctioning fuel injectors, powertrain control module (PCM) issues, sensor problems, and electrical issues can also contribute to this code.
Symptoms and Fix
As a result of the low voltage condition in the fuel injector control circuit, you may experience engine misfires or rough idling due to improper fuel delivery.
This can lead to decreased power and acceleration, poor fuel efficiency, and an illuminated Check Engine Light. Engine stalling or hesitation can also occur.
To fix the issue, inspect the wiring and connectors for damage or corrosion, test the fuel injector for proper operation, and check the powertrain control module for fault codes.
Verify proper fuel pressure to restore peak engine performance.
Cost and Additional Information
The cost of repairing a P0267 code can vary widely, depending on the specific cause and extent of repairs needed.
You’ll need to weigh factors like fuel injector replacement, which can range from $150 to $500, including parts and labor.
Labor rates can vary significantly, so shop around for the best rates in your area.
A clogged or partially clogged fuel injector may require an injector flush before replacement.
Consult a professional mechanic for a more precise cost estimate based on your vehicle’s make and model, taking into account.

Frequently Asked Questions
Can a Faulty Oxygen Sensor Cause a P0267 Code?
You’re wondering if a faulty oxygen sensor can trigger a P0267 code. While it’s unlikely, a sensor malfunction can cause issues that indirectly lead to low voltage in the injector control circuit, but faulty wiring is a more probable cause of this code.
Will a P0267 Code Clear Itself After Repairs?
When you finally get around to tackling that to-do list, don’t assume the P0267 code will clear itself after repairs. Make injector diagnosis a repair priority, as simply fixing the underlying issue won’t automatically erase the code – a manual reset is usually necessary.
Can a Low Battery Voltage Trigger This Code?
You’re wondering if a low battery voltage can trigger the P0267 code. Yes, it can, as a low battery voltage can cause a battery drain, which may be due to an Alternator malfunction, leading to a low voltage condition in the fuel injector control circuit.
Does a P0267 Code Always Indicate a Faulty Fuel Injector?
You should not assume a P0267 code always means a faulty fuel injector. It could be due to issues with injector resistance, fuel pressure, or the control circuit itself, so it’s essential to perform thorough diagnostics to identify the root cause.
Can a Tune-Up or Fuel Injector Cleaning Fix This Issue?
Did you know that 80% of fuel injector issues can be resolved with proper maintenance? In terms of fixing this issue, you’ll likely need more than just a tune-up or fuel injector cleaning. You’ll require a thorough fuel system diagnosis and possible injector maintenance to identify the root cause.
Conclusion
You’ve identified the P0267 code, but the real question is, can you diagnose the root cause? Is it a faulty fuel injector, a wiring issue, or something more sinister lurking in the powertrain control module? The symptoms are clear, but the fix is far from certain. Will you be able to track down the problem and get your engine running smoothly again, or will the mystery of the low voltage control circuit continue to haunt you?
