Ignition System: MIL On, Ignition Coil DTCs Set

Some 2006 Zephyr; 2006-2008 Fusion and Milan; 2007-2008 MKZ, Edge, and MKX; and 2008 Taurus, Taurus X and Sable vehicles may exhibit a malfunction indicator lamp (MIL) on with diagnostic trouble codes P0351, P0352, P0353, P0354, P0355 and/or P0356 present in the Powertrain Control Module (PCM) and with one or more damaged ignition coil-on-plug(s).

Secondary Ignition: The Art Of Spark

From the beginning of the internal combustion engine, several different ignition systems have been used to create a high-energy spark. The most popular system, and the one that’s in use today, is a step-up coil.

Staying ‘Current’ on Ignition Coil Changes

During the past century, ignition coil configurations have evolved from oil-filled canister to epoxy-filled to e-core to waste spark and to the most modern coil-on-plug or “pencil” coils. Whatever the configuration, an ignition coil creates a spark by transforming amperage into volts. To illustrate, an oil-filled ignition coil might require about 4 amperes of current
