The P0351 code means your engine control module (ECM) has detected a malfunction in the ignition coil “A” primary/secondary circuit, which corresponds to cylinder 1 on most engines. When this circuit ...

A windings road:It all starts with the concepts of inductance and electromagnetism. Inside an ignition coil there are two sets of wire windings (aka coils, that's why it's called a "coil," get it?).

An ignition coil is a vital component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into the high voltage needed to produce sparks at the spark ...

Ignition coils sit at the center of every gasoline engine’s spark, yet they usually stay invisible until something goes wrong. When a coil starts to fail, the symptoms can look like fuel problems, ...

Ignition coils play a crucial role in a vehicle's ignition system as essential components that facilitate the engine's combustion process. They are responsible for converting the low voltage supplied ...

Heat initiates the internal combustion process. Diesel engines utilize the temperature buildup from extremely high compression (pressure) to ignite the air/fuel mixture, with a little help from glow ...

Myth 1:A Voltmeter Is BestReality:A Scope Is Much BetterThe reason ignition systems are so hard to understand is because the flow of electricity cannot be seen. A common voltmeter used by many to ...

The ignition is easily the most misunderstood system in any car. Most enthusiasts treat ignitions like some sort of weird, black magic/voodoo curse best left alone until it fails. Either that or they ...

When you’re trying to learn about older cars, you might as well be signing up for the debate club. Every question, especially when it comes to breaker points, electronic, and multiple spark discharge ...
