What is an ignition coil and how does it work?

An ignition coil transforms ignition voltage (12 volts) to the very high voltage pulses (20,000 volts or more) that fire the spark plugs. The number of ignition coils varies depending on car model and year of production. Older cars will have one coil covering all engine cylinders while newer cars may have a coil-on-plug type arrangement — that is every cylinder will have its own dedicated ignition coil.

Ignition Coils

When to consider replacing an ignition coil:

  • Hard starting or no start. Ignition coils are subject to heat damage and electrical overload, both of which can cause partial or total failure. If the coil is faulty, you may have difficulty starting your car or it may not start at all.
  • Misfiring, loss of power, poor acceleration. Once the car is running, a bad ignition coil can cause poor operation of the engine. Should you have misfiring or loss of power, faulty ignition coils would be among the list of causes a mechanic would investigate. The Check Engine Light will often come on with a trouble code(s) indicating which cylinders are involved.

How do mechanics replace the ignition coil?

  • The ignition is checked to assure it is in the “off” position.
  • For single coils that supply all cylinders, the coil is disconnected from either a bracket located in the engine compartment or, in some cases, is removed from within the distributor. The replacement coil is secured and all electrical connections reattached. If the distributor was removed for any reason, the timing is adjusted as required.
  • For individual coil-on-plug applications, the coil is detached from the top of the individual spark plug and replaced.
  • Once the coil is securely in place, all electrical connections are reattached, and timing adjusted as needed, the car is road tested to ensure normal operation.

Is it safe to drive with an ignition coil problem?

Yes. A malfunctioning ignition coil will cause loss of power and lower fuel efficiency but that will not present an immediate safety issue. If the coil malfunction is causing misfiring, this will allow unburned fuel to enter and permanently damage the catalytic converter from overheating.

When replacing an ignition coil keep in mind:

  • Ignition coil failure can be caused by faulty spark plugs or wires. The mechanic will inspect and may recommend replacement of those components.
  • In a coil-on-plug ignition system, if only one coil fails, you need only replace the faulty coil. Remaining functioning coils can be left in place.
  • In systems with the coil located in the distributor, it may be more cost-effective to replace the entire distributor rather than remove and replace just the coil.

Mercedes-Benz SL600 V12-6.0L - Loud screeching noise when I start the car - Goodyear, Arizona
I have an older Mercedes 600SL and was somewhat concerned about using some one other than a dealer, but my fears were put to rest after my initial conversation with Steve. Steve was on time, knowledgeable, had all of the required tools. diagnose the problem and gave me a stalemate of cost for the repair. He did not try to over sale me on something I didn't need. He made the repairs made sure that everything was correct and assured me that if I needed anything more he was just a phone call awaly. Steve called me the next day just to check that the repair was good.

Mercedes-Benz SL600 V12-5.5L Turbo - Brake Pads Replacement (Front) - Huntington Beach, California
Highly recommend Chris and will request him next time I need service on my Mercedes SL600 V12 Turbo Roadster! Chris is an expert craftsman who really knows about my Mercedes. I was happy about saving money by not going to the dealer for service. Who knew you can have your car serviced at home while getting things done around the house instead of wasting time driving to a dealer and hanging out in their waiting area! I will definitely request Chris next time my car needs service!!
