What is OBD-II Code P0680 – Cylinder 10 Glow Plug Circuit/Open
When it comes to vehicle maintenance, one of the most important factors to consider is the health of your car’s engine. A well-maintained engine helps in achieving peak performance and fuel efficiency, among other benefits. One indicator of an engine’s health is the OBD-II code that it produces. If your car’s onboard diagnostic system detects an issue with the engine, it will produce an OBD-II code to signify the issue. Today, we’ll take a closer look at OBD-II Code P0680 – Cylinder 10 Glow Plug Circuit/Open.
What is OBD-II Code P0680?
OBD-II Code P0680 refers to an issue with the cylinder 10 glow plug circuit/open. A “glow plug” is a heating device that is used to preheat diesel engines to allow for a smoother start. The glow plug acts as a heat source, which promotes the combustion process and creates the energy needed for the engine to work. Code P0680 occurs when the circuit for the glow plug in cylinder 10 is open or has failed.
Symptoms of Code P0680
There are various symptoms of code P0680 that a vehicle owner may notice. One of the most common symptoms is difficulty starting the engine, especially in colder conditions. If the glow plug circuit for cylinder 10 is not working correctly, it may take longer for the engine to start. Additionally, the engine may misfire or produce a rough response when started.
Another symptom of Code P0680 is a decrease in overall engine performance. Faulty glow plugs lead to inefficient combustion, which can cause the engine’s power to decrease. Finally, drivers may notice a dashboard warning light that continuously illuminates.
