Phoenix Ignition Coil Repair

Getting your vehicle serviced or repaired isn’t something most drivers in Phoenix want to have to do. Unfortunately, it’s not always an option. At Perez Auto Repair of Phoenix we want to help you as much as possible and part of that is sharing helpful information about your vehicle. So when those unexpected breakdowns happen you’ll be a bit more prepared. One of those more unknown fixes may be your ignition coil. Some of the symptoms of a failing ignition coil include trouble starting your engine, stalling, misfires, backfiring, a decrease in gas mileage, and your engine dying abruptly after running for a while. Higher fuel consumption is caused by your engine using more fuel in order to make up for the lack of power. If you continue to drive your car with a bad misfire, it may lead to more extensive and expensive damage, so you should get it taken of as soon as possible.

In most vehicles, a failing ignition can also cause a check engine light warning on your dash. This is caused either by your car’s computer detecting misfires, or detecting an issue with the ignition signal or circuit, such as when a shorts or burns out. Keep in mind that a check engine light can also be caused by a wide variety of other issues, so having the computer trouble codes read by a professional is highly recommended. A failing ignition coil, in most cases, will also cause your check engine light to illuminate. At Perez Auto Repair we have all the latest diagnostic equipment to read those codes.

Now for a better understanding of an ignition coil, or spark coil. Simply put it’s a part of your vehicle’s ignition system which transforms your battery’s low voltage into the thousands of volts needed to create a spark in your spark plugs. Without the ignition coil, your battery would not put out enough voltage to generate the spark needed to ignite gasoline inside of your engine. Ignition coils contain a few components, including an internal or external resistor or resistor wire, high voltage wires, and in most cases, a power transistor which provides pulses to the ignition coil. Most cars also have a distributor, which splits current from the ignition coil to each of the spark plugs, but many modern cars use one ignition coil for each cylinder or pair of cylinders, and do not require a distributor.

In modern ignition systems, ignition is electronically controlled. Modern ignition coils that do not have to power every spark plug are much smaller, and can be mounted either remotely or directly on top of the spark plug – called direct ignition. Modern cars may have all of their ignition coils contained inside of a single molded block, commonly called a coil pack. Diesel powered vehicles do not have ignition coils, because they rely on compression to ignite the air/fuel mixture.
