WHAT DOES YOUR IGNITION COIL DO?

The Ignition Coil takes the battery’s 12-volt output and amplifies it to over 30,000 volts. This higher
voltage is then routed to the spark plug via coil boot or wire, which ignites the air/fuel mixture inside
engine’s cylinder.

WHERE IS THE IGNITION COIL LOCATED?

The Ignition Coil is mounted either directly to the top of the spark plug or near the spark plugs. The
Ignition Coil is connected to the spark plug(s) by the coil boot or ignition wires.

WHY DOES THE IGNITION COIL FAIL?

The primary cause for failure is voltage overload caused by worn spark plugs or damaged cables
and wires. The hot and cold temperatures plus engine vibrations can cause the coil’s windings and
insulation to break.

HOW TO DIAGNOSE A FAULTY IGNITION COIL?

The vehicle could experience misfiring, backfiring, hard starting, poor performance, or poor fuel
economy - these are all potential signs of a faulty ignition coil. The vehicle’s check engine light could be triggered by a faulty ignition coil.

HOW DO YOU FIX FAULTY IGNITION COILS?
