Common Questions
What does P0267 mean and how does it affect my car?
DTC P0267 indicates that the fuel injector for cylinder 3 is not receiving the necessary voltage to operate effectively. This can lead to engine misfires, poor acceleration, and reduced fuel efficiency, ultimately affecting the overall performance and reliability of your vehicle.
What are the most common causes of P0267 and how much does it cost to fix?
Common causes include faulty fuel injectors, damaged wiring, or a malfunctioning ECM. Repair costs can range from $100 for wiring repairs to $400 for injector replacement, depending on the severity and required repairs.
Can I drive my car with P0267 or should I stop immediately?
It's advisable to stop driving your vehicle if you have a P0267 code. Continuing to drive can cause further engine problems, leading to more extensive and expensive repairs.
How can I diagnose P0267 myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for diagnostic trouble codes, view freeze frame data, and monitor real-time data to identify issues. Check the voltage levels at the fuel injector while the engine is running to verify if it's receiving adequate power.
What vehicles are most commonly affected by P0267?
P0267 is often seen in Ford and GM vehicles, including popular models like the 2011 Chevrolet Silverado and the 2013 Ford F-150, particularly in those with higher mileage.
How can I prevent P0267 from happening again?
Regular maintenance is key. Ensure routine inspections of the fuel system and electrical components, and use quality fuel to minimize injector clogging. Keeping the engine clean can also help prevent future codes.
What is P0267?
The diagnostic trouble code (DTC) P0267 indicates an issue with the fuel injector circuit, specifically related to low voltage detected in the cylinder 3 fuel injector. This code is prevalent in various vehicle makes, particularly Ford and General Motors (GM) models produced between 2000 and 2015. When the engine control module (ECM) detects a voltage reading that is below the expected threshold for the fuel injector circuit, it triggers this code, signaling a potential problem that could affect engine performance. The low voltage condition may result from several factors, including faulty wiring, a bad fuel injector, or issues within the ECM itself. Drivers may notice a range of symptoms such as engine misfires, reduced fuel efficiency, or even stalling. Addressing this issue promptly is crucial, as neglecting it can lead to further engine damage or more costly repairs down the line. If you encounter this code, it is advisable to conduct a thorough diagnostic process to pinpoint the underlying issue, ensuring the reliability and performance of your vehicle.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0267 is present:
- Check engine light illuminates and stays on, indicating a fault that needs attention.
- Engine misfires or hesitates during acceleration, leading to a rough driving experience.
- Fuel economy decreases significantly, often by 10-20%, due to inefficient fuel delivery.
- Rough idle or stalling when the engine is at low RPM, causing potential safety issues.
- Increased emissions, potentially failing an emissions test due to improper combustion.
Possible Causes
Most common causes of P0267 (ordered by frequency):
- Faulty fuel injector is the most common cause (approx. 40% likelihood). Over time, fuel injectors can become clogged or fail, leading to poor performance.
- Damaged wiring or connectors in the fuel injector circuit (30% likelihood). Corrosion or breaks in the wiring can disrupt electrical flow.
- Faulty engine control module (ECM) can cause low voltage readings (15% likelihood). This is less common but can lead to serious issues if the ECM is malfunctioning.
- Fuel pump issues (10% likelihood). A failing fuel pump may not supply adequate pressure to the fuel injectors, leading to low voltage readings.
- Less common but serious, a vacuum leak could disrupt air-fuel mixture, affecting injector performance.
