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 circuit is made up of two sub-circuits: the primary, which carries low voltage; and the secondary, which carries high voltage. The primary circuit is controlled by the ignition key. 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 ...

For the average beginner in the fine art of auto mechanics, and some old-timers as well, installing and wiring a stock eight-cylinder ignition distributor can sometimes be quite a chore, and when he ...

Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the ...
