This code means there's a problem with the little heater (glow plug) in cylinder 6 of the engine. It's not getting enough power to work properly.
The glow plug in cylinder 6 is not receiving enough voltage, which is necessary for it to heat up and help start the engine.
The P067E code indicates that the Engine Control Module (ECM) has detected a low voltage condition in the glow plug circuit for cylinder 6. Glow plugs are used in diesel engines to heat the cylinders and aid in starting the engine, especially in cold conditions. A low circuit condition means the glow plug is not receiving sufficient electrical power to operate effectively.
• Difficulty starting the engine, especially in cold weather
• Check Engine Light illuminated
• Rough idle during cold start
• Faulty glow plug
• Wiring issues in the glow plug circuit
• Defective glow plug control module
Glow Plug: A device used to heat the air in a diesel engine cylinder to aid in starting.
ECM: Engine Control Module, the computer that controls engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the glow plug for cylinder 6 for proper resistance.
• Replace the faulty glow plug.
• Repair or replace damaged wiring or connectors.

Moderate
• Ford F-250
• Chevrolet Silverado
• Dodge Ram 2500
• Regularly inspect and maintain the glow plug system.
• Ensure electrical connections are clean and secure.
• Use high-quality glow plugs.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Consider regular maintenance checks to prevent future issues.
Glow plugs may be covered under the vehicle's powertrain warranty. Check with the manufacturer.
Glow plug issues are common in diesel engines, especially in colder climates where they are crucial for starting the engine.
Moderate – While the vehicle may still operate, starting issues can worsen, especially in cold weather.
Driving with a malfunctioning glow plug can lead to increased emissions and potential engine damage.
• Engine cold start
• Ambient temperature below freezing
The glow plug for cylinder 6 is located in the engine block, near the sixth cylinder.
Q: Can I drive with a P067E code?
A: It's possible to drive, but starting the engine may be difficult, especially in cold weather. It's best to fix the issue promptly.
Q: How do glow plugs work?
A: Glow plugs heat the air in the cylinder to help start a diesel engine, especially in cold conditions.
