Component Details:
An
ignition coil
(also called a
spark coil
) is an induction coil in an automobile's ignition system which transforms the
battery's low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel.
The wire that goes from the ignition coil to the distributor and the high voltage wires that go from the distributor to each
of the spark plugs are called spark plug wires or high tension leads.
Preliminary Checks:
1) Loose/ Damaged Connections between Ignition coil B and EMS ECU.
2) Check for back out of pins at both Ignition Coil connector and ECU connector.
3) Check for damage of pins at both Ignition Coil connector and ECU connector.
