Fuel System > Engine Control System > P0356 Ignition Coil 'F' Primary / Secondary Circuit
Component Location
General Description
With the ignition switch in the ON or START position, voltage is applied to the ignition coil. Each ignition coil consists of
two coils. High tension leads go to each cylinder from the ignition coils. The ignition coils fire two spark plugs on every
power stroke (the cylinder under compression and the cylinder on the exhaust stroke). The Engine Control Module
(ECM) provides a switching circuit to ground for energizing the primary ignition coils. The ECM uses the crankshaft
position sensor and camshaft position sensor signal to time the energizing of the coil. When a primary ignition coil is
energized and de-energized, the secondary coil produces a high voltage spike to the attached spark plugs.
DTC Description
Checking output signals from ignition coils every 10 sec. under detecting condition, if the signals indicating open or
short in the circuit are detected for more than 5 sec., ECM sets this DTC. MIL(Malfunction Indication Lamp) turns on
when the malfunction lasts till consecutive 2 driving cycle.
