Saturn Ion-2 Ignition Coil

Bad Indicators of a Saturn Ion-2 Ignition Coil Going Down the Dumps

The internal combustion engine is one of man's greatest contributions to society. The one part that starts the ball rolling is called the ignition coil. The ignition coil is a simple electromagnet that cranks up the engine, providing as much as 100,000 volts of energy to make sure that all is running well. With such a big responsibility, this part will undoubtedly fail in the passing of time. But before it goes bye-bye, fortunately, there are signs that can help you figure out what's wrong. Here are those indicators when the ignition coil is at its last leg.

Declining fuel economy

Let's start with the most subtle of all the indicators. Declining fuel economy is, of many things, caused by the lack of power received by the spark plugs to start the combustion process. A defective ignition coil is sure to be a suspect for this one because it provides the primary and necessary energy for the spark plugs to work. With less power, the fuel can't be burned fully. Thus, the car feels sluggish. More fuel than usual has to be burned in order to provide the acceleration needed at high speeds. Therefore, the fuel economy of your car will decrease dramatically.

Backfires in the exhaust

With this indicator, you're going to realize more and more that the problem might be with the ignition coil. Backfiring occurs when the fuel that is not completely combusted continues to burn off inside the exhaust system. This creates a small explosion and can make gaskets and seals in the exhaust come loose. These backfires must be corrected immediately before the problem takes a turn for the worse.

Problems with starting the engine

By now, you already know that the ignition coil acts like an instigator for the combustion engine to get fired up. Obviously, when the ignition coil goes bad, it cannot give the means for the spark plug to ignite the combustion and therefore, the car will be suffering from hard starting. The car will have a harder time starting once the cold days arrive or if humidity is high so consider yourself warned.

Engine misfires.

Misfires in the engine is manifested through stuttering, vibrating, hesitating, jerking, and stalling; all of which are spark plug problems. However, if upon investigation and you find out that there's no fault with the spark plug, then the problem lies with the ignition coil. Like the other symptoms, this is caused by an ignition coil failing to supply electricity to the spark plug regularly and properly.

  • Make Your Saturn Ion-2 Ignition Coil Stay Alive

    The ignition coil is as important as any other engine part in the vehicle. The engine needs a constant supply of power to keep it going, and the ignition coil provides that. Therefore, taking care of the ignition coil is imperative to maintain the engine's overall wellness. You can make use of these easy maintenance tips to make sure that the ignition coil in your Saturn Ion-2 is alive and kicking.


    Check the resistance reading.


    Resistance is a mode of measurement used to recognize if the part can make use of the power or electricity that is supplied. Reading the resistance of the ignition coil is a great place to start knowing if it's messed up or not. All you need here is a good old-fashioned multimeter. This tool is great for a lot of other uses aside from checking engine parts. By placing the multimeter's probe on the negative and positive terminals a reading of 0.7 to 1.7 ohms must be shown for the primary resistance. For the secondary resistance, the reading should be 8,000 to 11,500 ohms.


    Make sure it's rust-, moisture-, and corrosion-free.


    The ignition coil is made of metal, so it can become rusty once it gets old and moisture creeps in to its surface. Rust can do a lot of bad things to your ignition coil. For one, it can mess up the contact between the terminals in the coil and the connectors that supply it with electricity. Therefore, rust, moisture, corrosion and, engine muck are to be kept away from the ignition coil. Remember to just wipe it up with dry, lint-free cloth from time to time in order to prevent rust from accumulating. You can also use an air blower to sweep away any moving bits and pieces off the surrounding area. Disconnecting the negative battery terminal is utterly important to ensure your safety against electrocution.


    Test the wires.


    If the wires get tripped for some reason, electricity won't be able to flow from the battery to the coil then to the spark plugs. Use a test wire and test the wiring one by one to pinpoint which wire exactly has the problem.
