Tips on Diagnosing Nissan Altima Ignition Coil Problems
The ignition coil in your Nissan Altima is one of those parts that don't usually cause any trouble, but when it does it leads to huge headaches. Also known as the spark coil, the Nissan Altima ignition coil is part of the modern automobile's ignition system which converts the dismal voltage of the car battery into the thousands of volts needed by the spark plug to ignite the fuel and air mixture in the engine cylinders. Typically, an ignition coil can last for 60,000 to 100,000 miles before starting to show signs of wear, but various factors such as abnormally high operating temperatures and adverse weather conditions can cause the coil to wear out prematurely. In this article, we're going to discuss some of the common problems of Nissan Altima ignition coils and how to diagnose them.
Overheating is one of the worst kinds of ignition coil failure, and it's typically due to excessive spark gap. Spark plugs that have wide gaps need more voltage in order for the spark to jump from one electrode to another. This creates additional load on the ignition coils and causing it to overheat. Even if the coil survives the overheating in one piece, the excessive heating and cooling process causes the coils to expand and contract, reducing their integrity and eventually leading to malfunction or total breakdown of the coil.
Backfiring and misfiring
If your Altima is frequently backfiring or misfiring, it could mean a loosely connected or poorly mounted ignition coil. Loose ignition coil wirings or improper mounting can damage to the ignition coil and result in complete failure of the device. Loose spark plug wires can also cause the coil to fail, as the high voltage the spark produces can jump to the coil and damage it in the process.
On the other hand, if you are having trouble starting the engine the spark plug may no longer be receiving enough charge from the ignition coil. This problem is especially noticeable during cold weather or in environments where there is high humidity, as it would be next to impossible to start the car up during such conditions.
