As you navigate the complex landscape of engine troubles, a P0268 code emerges like a warning lighthouse on the horizon, signaling a problem with the fuel injector control circuit for cylinder 3. Specifically, it’s triggered by higher-than-specified voltage in the injector circuit. This could be due to a faulty fuel injector, wiring issues, or even an ECM problem. You’ll likely notice symptoms like rough idling, misfires, and poor fuel economy. But what’s behind this code, and how do you get your engine running smoothly again?
Quick Navigation
Key Takeaways
- The P0268 code indicates a problem with the control circuit of the fuel injector for cylinder 3, causing issues with the injector’s operation.
- A faulty fuel injector, wiring issues, or a problem with the Engine Control Module (ECM) can trigger the code.
- Rough idling, engine misfires, hesitation, and poor fuel economy are common symptoms of the P0268 code.
- Inspect and repair or replace the wiring harness and connectors, and test the fuel injector for cylinder 3 to diagnose the issue.
- The estimated cost to address the P0268 code is between $150 and $500, depending on the root cause and required repairs.
Code Description and Causes
The P0268 code indicates a problem with the control circuit of the fuel injector for cylinder 3 in your engine.
When this code appears, it means the voltage in the injector circuit is higher than the specified range, causing issues with the injector’s operation.
A faulty fuel injector for cylinder 3 is a possible cause, as well as wiring issues in the injector control circuit.
Even a problem with the Engine Control Module (ECM) can trigger this code.
It’s essential to identify the root cause to prevent further engine damage.
Symptoms and Fix
Rough idling is often the first sign that something’s amiss, and it’s usually accompanied by engine misfires and hesitation or stumbling during acceleration.
You may also notice poor fuel economy and engine stalling. The rough idling causes can be attributed to the faulty fuel injector or wiring issues in the injector control circuit.
To fix the issue, inspect the wiring harness and connectors for damage or corrosion and repair or replace as needed. You should also test the fuel injector for cylinder 3 to determine if it’s faulty and replace it if necessary.
Cost, Tech Notes, and Resources
You’ll need to budget between $150 and $500 to address the P0268 code, depending on the extent of the repairs required.
This estimate includes the cost of repair or replacement of the faulty fuel injector, wiring repairs, or ECM issues.
For accurate repair estimates, consult a trusted mechanic or repair shop. Don’t forget to clear the diagnostic trouble codes from your vehicle’s memory using a scan tool, a vital step in the repair process.

Frequently Asked Questions
Can I Drive My Car With a P0268 Code?
You can drive your car with a P0268 code, but it’s not recommended as it can lead to poor fuel efficiency, decreased engine performance, and potentially cause further damage, especially if the issue persists over time.
Will a P0268 Code Cause Damage to My Engine?
Did you know that fuel injector issues can reduce engine performance by up to 20%? If you’re driving with a P0268 code, you’re risking cylinder wear and potentially causing permanent engine damage, as the high voltage can lead to overheating and premature wear on moving parts.
Can a Fuel Injector Cleaner Fix a P0268 Code?
You’re wondering if a fuel injector cleaner can fix the issue. While it might help remove clogs in the fuel system, it’s unlikely to resolve the high voltage problem in the injector control circuit, requiring a more thorough diagnosis and repair.
How Long Does It Take to Repair a P0268 Code?
You’ll typically spend around an hour to several hours repairing a P0268 code, depending on whether you need to replace the faulty injector or diagnose issues in the control circuit, which may involve inspecting wiring harnesses and connectors.
Will a Tune-Up Fix a P0268 Code?
As you rev up your engine, a tune-up might not be the silver bullet you’re hoping for – it won’t fix the underlying issue of high injector resistance or faulty fuel pressure, which are likely causing your code.
Conclusion
You’ve diagnosed a p0268 code, indicating a high voltage issue in the control circuit of your cylinder 3 fuel injector. Don’t ignore it – a faulty fuel injector can decrease your engine’s performance and fuel efficiency. Did you know that a faulty fuel injector can decrease your gas mileage by up to 20%? Fixing this issue promptly can save you money and prevent further damage to your engine.
