Hyundai Tucson: On-vehicle- Inspection
Inspect ignition coil assembly and Perform spark test
- Check for DTCs.
WARNING
If a DTC is present, perform troubleshooting in accordance with the procedure for that DTC.
(Refer to DTC guide)
- Check if sparks occur.
Without diagnostic tool
(1) Remove the engine cover.
(Refer to Engine Mechanical System - "Engine Cover")
(2) Remove the ignition coils.
(Refer to Ignition System - "Ignition Coil")
(3) Using a spark plug wrench, remove the spark plugs.
(Refer to Ignition System - "Spark Plug")
(4) Connect the connector after install the spark plug to ignition coil.
(5) Ground the spark plug to the engine.
(6) Check if sparks occur at each spark plug while engine is being cranked.
WARNING
Do not crank the engine for more then 5 seconds

Description
The ignition coil is mounted on the top side of the cylinder head cover end. The ignition coil consists of the primary coil that receives battery power and the secondary coil that generates high voltage.
When the current in the primary coil is cut off by the ignition signal of the ECM, the rapid change of the magnetic flux by the mutual induction action is induced to the secondary coil and high voltage is generated depending on the coil winding ratio.
This high voltage generated from the secondary coil is caught in the spark plug gap and discharges as the electric field is destroyed to generate a spark.
