Common Questions
What does P067F mean and how does it affect my car?
The P067F code indicates a problem with the glow plug circuit, crucial for starting your diesel engine, especially in cold weather. If ignored, it can lead to hard starts, rough idling, and increased emissions.
What are the most common causes of P067F and how much does it cost to fix?
Common causes include faulty glow plugs (60% likelihood), damaged control modules, or poor electrical connections. Repair costs typically range from $150 to $600 depending on the specific issue.
Can I drive my car with P067F or should I stop immediately?
It's best to avoid driving your vehicle with this code, especially in cold conditions, as it can lead to further engine issues and potentially leave you stranded.
How can I diagnose P067F myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for trouble codes, view live data from the engine, and check the status of the glow plugs. This helps you understand the issue's context before consulting a professional.
What vehicles are most commonly affected by P067F?
The P067F code is frequently seen in diesel models, particularly the 2015-2018 Ford F-250 and similar diesel vehicles from other manufacturers, such as the 2016-2019 GMC Sierra.
How can I prevent P067F from happening again?
Regular maintenance such as checking glow plugs during service intervals, ensuring clean fuel, and inspecting electrical connections can help prevent the recurrence of the P067F code.
What is P067F?
The P067F diagnostic trouble code indicates a malfunction in the glow plug circuit, specifically related to the glow plug's performance, which is crucial for starting diesel engines under cold conditions. This code is particularly prevalent in diesel vehicles like the 2015-2018 Ford F-250. When this code appears, it means that the Engine Control Module (ECM) has detected an issue with the glow plug or its control circuit. The glow plugs heat the air in the combustion chamber, making it easier for the engine to start when temperatures are low. If the glow plugs aren’t functioning correctly, the engine may experience hard starts, increased white smoke during startup, and rough idling. Ignoring this code could lead to further complications, such as damage to the engine components due to improper combustion and increased fuel consumption. Therefore, it's essential to address the P067F code promptly to maintain optimal engine performance and reliability.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P067F is present:
- Check engine light remains illuminated, indicating an underlying issue with the glow plug system.
- Engine hesitates during initial startup, especially in cold weather conditions, leading to possible stalling.
- Fuel economy may decrease by 10-15% due to inefficient combustion caused by malfunctioning glow plugs.
- Rough idling when the engine is cold, resulting in a shaky driving experience until the engine warms up.
- Increased exhaust smoke, particularly white smoke during startup, indicating incomplete combustion.
Possible Causes
Most common causes of P067F (ordered by frequency):
- The most common cause of P067F is a faulty glow plug, which has a likelihood of about 60%. This could be due to wear and tear over time.
- A damaged glow plug control module is another frequent cause, as it may fail to send the proper signals to the glow plugs, affecting their performance.
- Poor electrical connections or corroded wiring can lead to insufficient power reaching the glow plugs, which is a common issue in older vehicles.
- Less common but serious causes include a malfunctioning ECM that fails to recognize the glow plug's condition.
- Rarely, issues with the fuel system, such as low fuel pressure or contaminated fuel, can contribute to starting problems that may trigger the P067F code.
