How are coil on plugs used in spark plugs?
Coil-on-plug assemblies are designed to convert a low voltage (primary side) to a high voltage (secondary side) to fire the spark plugs. They perform the functions of both the ignition coil, which creates the spark energy.
What does zero mean on a spark plug ignition coil?
If a reading of zero is displayed, that signifies that the ignition coil has shorted internally in the primary windings and needs to be replaced. A reading over the specification signals that the ignition coil is open, which would also indicate a need to replace the coil.
How many wires are in a coil on plug?
Today’s coil-on-plug assemblies come in a variety of physical and wiring configurations. The typical configurations are two wires, three wires and four wires. Some ignition coils contain a solid-state driver module, which is part of the ignition coil and is controlled by the Powertrain Control Module (PCM).
What is an ignition coil and what does it do?
An ignition coil is a vital component of today’s modern engine management system. Virtually all vehicles manufactured today use ignition coils to provide the spark for the engine’s spark plugs. An ignition coil is an inductive coil that is a part of the vehicle’s secondary ignition system.
How often do I change my spark plug coils?
While experts generally recommend replacing them every 30,000 miles, it will vary depending on your specific model. Refer to your owner’s manual for specific information.
Can a bad coil cause weak spark?
Either one of these windings can go bad and cause your ignition coil to fail. Sometimes an ignition coil is clearly bad because it makes no spark at all. But if a coil is only on its way out and not yet dead, it can make a weak spark that will make your car run poorly.
