This code means that there is a problem with the part of the car that helps start the engine when it's cold, specifically for the tenth cylinder.
The P06C2 code indicates an issue with the glow plug circuit for cylinder 10, which is not performing within the expected range.
The glow plug is an essential component in diesel engines, used to preheat the cylinder for efficient combustion. The P06C2 code signifies that the Engine Control Module (ECM) has detected a performance issue or out-of-range condition in the glow plug circuit for cylinder 10. This can affect starting and operation in cold conditions.
• Difficulty starting the engine in cold weather
• Check Engine Light illuminated
• Rough idle or misfire when cold
• Faulty glow plug in cylinder 10
• Wiring issues such as shorts or opens in the glow plug circuit
• Faulty glow plug control module
Glow Plug: A device used to preheat the air in a diesel engine cylinder to aid in starting.

Engine Performance
• Have the vehicle inspected by a professional if the Check Engine Light is on.
• Avoid driving in extremely cold conditions until the issue is resolved.
Glow plugs may be covered under the vehicle's powertrain warranty. Check with the manufacturer.
Glow plug issues have been a common problem in diesel engines, especially in colder climates, due to their critical role in starting and efficient combustion.
Moderate – While the vehicle may still operate, it can have starting issues in cold weather, affecting reliability.
Addressing this code promptly ensures safe and reliable vehicle operation, especially in cold weather conditions.
• Cold engine start
• Ambient temperature below freezing
The glow plug for cylinder 10 is located in the engine cylinder head on the tenth cylinder.
Q: What happens if I ignore the P06C2 code?
A: Ignoring this code can lead to starting issues, especially in cold weather, and may cause further engine problems.
Q: Can I drive with a P06C2 code?
A: You can drive, but it's advisable to fix the issue soon to prevent starting problems in cold conditions.
