Ignition coil failures are caused by worn out spark plugs that fail to transmit electronic signals in a functional and fluid manner. This creates a disruption in the regular flow of power across the ignition coil and makes the engine lose power. It is less common but still possible that the rotor the ignition coil rests on breaks and reduces the function of the power circuit.Continue Reading
The ignition coil is the primary tool used between the battery and the rest of the engine in terms of transmitting electrical power from one point in the machinery to the entire combustion process. This device sits on a high-powered rotor that allows for fluid movement as the coil transfers electricity along the cylindrical path of its metallic frame. When spark plugs fail to transmit electrical information in the right sequence and frequency, this causes significant issues that result in ignition coil failure.
An ignition coil failure is easy to detect thanks to the visible ways it impacts the engine. Cars and trucks with ignition coil failure experience backfiring, misfiring and problems with getting the vehicle to start in the first place. When drivers encounter issues with maintaining power in the automobile, it is likely that the issue is an ignition coil failure.Learn more about Car Parts & Maintenance
The ignition system of an automobile draws electrical current from the battery, increases the voltage using an induction coil, and distributes the current to the spark plugs to ignite the fuel-air mixture. The distributor and an ignition-timing system ensure that current flows to the correct cylinder as fuel enters the system, keeping the engine firing efficiently.Full Answer >
To use a compression test to diagnose an engine, first disconnect the fuel pump, fuel injection fuses, the wire leading to the coil and spark plugs, and all spark plugs. Next, place the end of the compression gauge into one of the spark plug holes, inserting the threaded end first. Turn on the ignition and press on the throttle until the engine hits four revolutions. If the reading on the compression gauge is unstable, try taking it to 10 revolutions.Full Answer >
A coil pack, also referred to as an ignition coil, is a component in the car's engine that changes current generated by the battery into a high-voltage current used by spark plugs. A typical coil pack transforms the 12 volts generated by the battery to the required voltage.Full Answer >
The spark plugs on a Kia Sportage are located under the coil cover. Removing this cover reveals the ignition coils, wires and plugs. About.com states to note carefully where the wires are placed before removal to avoid crossing them after the plug replacement.Full Answer >
