FAQ About Ignition Coil
how to test ignition coil?
Look at it – Check for cracks, burns, or loose wires.
Check the spark – Use a spark tester or a spare spark plug. A strong, blue-white spark means the coil works; weak or no spark means it might be bad.
Measure resistance – Use a multimeter:
Primary coil (terminals): around 0.4–2 ohms.
Secondary coil (to high-voltage output): around 6k–15k ohms.
Very high or zero readings usually mean the coil is faulty.
Swap test – Replace it with a known good coil. If the problem moves with the coil, it’s faulty.
bad ignition coil symptoms
Engine misfires – The car shakes or runs rough, especially under load.
Hard starting – Engine struggles or takes longer to start.
Poor fuel economy – Coil issues can cause incomplete combustion.
Check Engine Light – Often triggers misfire codes (P0300–P030X).
Loss of power – The vehicle feels sluggish during acceleration.
Backfiring or unusual exhaust – Unburned fuel ignites in the exhaust system.
what does an ignition coil do？
An ignition coil is like a small transformer for your car’s engine. Its job is to take the low voltage from your car battery and turn it into a very high voltage. This high voltage is what creates a spark in the spark plugs, which then ignites the fuel-air mixture in the engine cylinders. Without the ignition coil, your engine wouldn’t be able to start or run, because there would be no spark to ignite the fuel.
how long do ignition coils last?
Ignition coils usually last anywhere from 100,000 to 150,000 miles (160,000 to 240,000 km), but it can vary depending on your car, driving habits, and the quality of the coil. Heat, vibration, and moisture can wear them out over time, so even if your car hasn’t hit that mileage, a coil can fail earlier.
how many ignition coils does a car have?
The number of ignition coils in a car depends on the engine type and design:
4-cylinder engine: usually 4 ignition coils (one per cylinder).
6-cylinder engine: usually 6 ignition coils.
8-cylinder engine: usually 8 ignition coils.
Some older cars use one coil for multiple cylinders with a distributor, but most modern cars have one coil per cylinder for more reliable sparks and better engine performance.
