Testing a coil pack with a multimeter is a crucial step in diagnosing ignition system issues in vehicles. A coil pack is responsible for providing high-voltage electricity to spark plugs, which ignite the air-fuel mixture in the engine’s cylinders.
A faulty coil pack can lead to misfires, reduced engine performance, and increased emissions. Using a multimeter to test a coil pack allows you to quickly and accurately determine if it is functioning properly.
