General Description

When the ignition switch is 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 ignition coils. Ignition coils fire two spark plugs on every power stroke (the cylinder under compression and the one on the exhaust stroke). PCM provides ground to a switching circuit for energizing the primary ignition coils. PCM uses the crankshaft position sensor and camshaft position sensor signals to meet the timing of energizing coil. When a primary ignition coil is energized or de-energized, the secondary coil produces a high voltage spike to the attached spark plug.

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., PCM sets this DTC. MIL (Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
