What are the symptoms and causes of spark plug wire faults? What causes a broken spark plug wire? What happens when the spark plug wire breaks? What is the purpose of spark plug wire?
Spark plug wires are an integral part of the ignition system. They are used in many vehicles. Newer vehicles may have an additional ignition coil. The spark plug wire is responsible for transferring electricity from the distributor or ignition coil to spark plugs. Spark plugs produce sparks at regular intervals in order to ignite the mixture of air and fuel. The spark plug wire can cause many problems in an engine. It is therefore important to check it first in the event of a malfunction.
Spark plug wires become less durable over time because of extreme temperatures and fluid contact (water, oil or antifreeze). There are also electrical stresses. The most obvious signs of malfunction include loss of power, difficulty operating the vehicle, increased fuel consumption, and hesitation in sudden accelerations. You may also notice the engine fault lamp come on, and hydrocarbon emission.
What Causes a Spark Plug Wire to Break?
Spark plug wires made from quality materials can withstand harsh environments. It works even in extremely difficult environments. They will eventually fail, regardless of how good they are. You should inspect the cable visually to check for any melting, rust, or disconnection. All conditions must be checked. The spark plug wire must also be replaced in these cases.
- Excessive vibrations can wear the wires and cause a loosening of the electrical connection between wire socket and spark plug. This can increase the voltage necessary to ignite the spark plugs. This can cause damage to the spark plug wire and ignition coil.
- – Cable insulation and housing can be melted by the heat from the motor. A damaged seat wire can cause spark plugs to stop working properly. This can cause voltage to jump.
- Spark plug wires can cause damage and fractures when they rub against sharp edges on the engine. In these cases, the electric current could jump to the engine block and not the sparkplug.
What are the Signs of Spark Plug Wire Problem?
- – Difficulty starting your vehicle
- Engine misfiring
- – Engine misfire and jerky racing
- – Idle fluctuation
- – Engine loss and hesitation during sudden acceleration
- – An increase in fuel consumption
- Stopping problems
- – Illumination for the check engine warning light
- – Potential malfunctions of electronic parts such as radios and GPS
