P0350 2002 KIA SEDONA - Ignition Coil Primary/Secondary Circuit
- Ignition Coil Primary/Secondary harness is open or shorted
- Ignition Coil Primary/Secondary circuit poor electrical connection
- Faulty Engine Control Module (ECM)
- Lack/Loss of Power
- Engine may be harder to start
- Engine hesitation
- Rough engine idle
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.
