Best Ignition Coils For Toyota Corolla – Comparison Chart with Features

Why do people vastly prefer Toyota Corolla? Because of its fuel efficiency with low-cost maintenance, right? Let me give you a reality check; forget about good mileage and cheap maintenance if you don’t use the best ignition coils for your Corolla.

Toyota Corolla ignition coils aren’t expensive at all. Most of them come at a reasonable price. You don’t have to hesitate too much in replacing old plugs. Here are 10 options for you that can both perform and last longer.

How To Choose Ignition Coils For Toyota Corolla?

Ignition coils are available with different features; they are not universal. Therefore, it is important that you use a checklist before purchasing a new ignition coil.

Type Of Coil

The coils can differ according to the ignition system of the engines. Coils such as single coil, coil packs and coil-on-plug are the one of the most basic coil designs that are used in ignition systems. So, check what type of coil your engine needs.

Single coil: There is only one coil which transfers power to all spark plugs and it can be externally located inside the distributor cap.

Coil packs: Car engines might have multiple cylinders and to ignite them you would need coil packs. Here, one coil can supply power to 2 spark plugs at the same time. The number of coil packs generally depends on the following configuration:

4 Cylinders	2 Coils
6 Cylinders	3 Coils
8 Cylinders	4 Coils

Coil-on-Plug: If you have a Direct ignition system in the engine, you will require individual coils for each spark plug. You can spot them near or over the plugs.

Primary Resistant

It is measurement of the level of current flow which passes through the primary windings of the coil. The electric distributors of the engines need to have a coil which can provide a minimum primary resistance. So, it ensures that the spark plugs get maximum voltage to create sparks.

You can measure the resistance with a multimeter like the Actron CP7677 digital multimeter. The value should normally read between 0.4-2 ohms. Coils with higher energy will have lower primary resistance.

However, the current may damage the distributor points if the resistance is too low. Hence, before buying the coil, ensure the compatibility of the primary resistance with the other components of the ignition system.

Turns Ratio: The ratio mainly shows the comparison of numbers of the windings used in primary and secondary circuits. The higher ratio indicates the higher amount of voltage. The general ratio is 100:1.

Maximum Output Of Voltage: On an average ignition coil can produce 20,000 to 30,000 volt powers. So, check the amount of the voltage that the coils can supply when you go to purchase them.

Replacement Part Numbers: Before changing the ignition coils, ensure that the replacement parts are compatible with your car model and manufacturing year. For example, the ECCPP ignition coils pack will have the right replacement parts for Corolla 1999-2008 cars, but they will not work for cars made between 2009-2017.

OEM: It is important to choose the replacement coils made by the original equipment manufacturer. As they make the parts with the same materials and for the same specifications, it is wise to select OEM components. So, in the case of Corolla, try to find coils which are made by the company to use as a replacement part.

It is a single 90919-02258 coil.

Car Manufactured from 2009 to 2017

Below you will find the answers of some common questions about the ignition coils:

Why Are Ignition Coils Important?

Ignition coils are mainly electric power transformers which help to convert the low voltage into a high voltage power through the spark plugs. The spark plugs use the power to create a spark in the engine cylinder so that the fuel gets ignited and forces the cylinders to move.

This movement causes the engine to spin and subsequently makes your car wheels roll over the road. So, in order to start your car engine or in other words to keep the vehicles usable, you need ignition coils.

What are the symptoms of Bad Ignition Coils?

Whenever your ignition coils go bad, it starts causing some problems. If the following things are happening to your car, it is because the coils are failing or have already failed:

Check Engine Light (CEL) Illuminates: If for some reason the coils fail, it will cause misfire in the engine and the CEL will be illuminated in the instrument cluster. To be sure of the misfire, you can connect an OBD2 scanner like ANCEL AD310 to your car and look for error codes from P0300 to P0312. If you see any codes from this range, it means that there is a misfire in your car engine.

Slow Acceleration: When the ignition coils fail, it causes the engine to lose power. As a result you won’t be able to accelerate your car to the desired speed.

Idle Gets Rough: If you see that the engine is not running smoothly in the time of idling, it means the coils are in bad condition. You may even feel a bit of vibration in the cabin.

Excessive Fuel Consumption: Your car will start to consume a lot of fuel when the ignition coils start to fail. You will also notice that the car is really getting lower gas mileage.

Difficulty In Starting: Due to the lack of ignition energy, the spark plugs won’t be able to produce enough sparks to ignite the fuels. So, it will be hard to start the engine or worse the engine may not start at all until you replace the ignition coils.

What Can Cause Ignition Coils To Go Bad In Toyota Corolla?

One thing you should remember is that with time these coils eventually fail, however, they can also fail prematurely due to the following reasons:

Oil Leakage In The Spark Plug Wells: When there is oil leakage in the spark plug tube, it causes misfires in the engine, hence, damages the coils. You can solve the problem just by replacing the seals.

Faulty Connectors Or Wires: Sometimes the electrical wires connected to ignition coils can get damaged which ultimately leads to the power failure in the coils. If you use a code scanner and notice that it is showing error codes between P0350 to P0362, it means there is a circuit malfunction in your engine.

Blown Fuse: Due to the faulty fuse, the circuit gets interrupted and consequently, the coils fail to produce power in the engine. In order to check the fuse, you have to pull out the fuse box by using a fuse puller. Then hold it against the light and see whether the metal strip in the middle is broken or not. If it is broken, it means the fuse has blown and it would require a replacement.

How To Replace The Bad Ignition Coil in a Corolla?

Though the ignition coils differ according to the car manufacturing years, the process of changing them is more or less the same. In order to replace them you will need only two things:

• A socket set or a wrench
• Corolla ignition coil

Once you have the equipment, follow the given steps to change the coils:

• Step 1: Open the hood and remove the plastic cover from the engine (if it has any cover).
• Step 2: Now disconnect the cables from the negative battery so that you don’t fall into any accident.
• Step 3: By using a wrench or a socket set, loosen up the nuts and clips that keep the cylinder head cover right in place.
• Step 4: Then inspect whether you need to change one coil or all of the coils. The coils are connected to the cylinder head by the connectors. They also ensure that the coils are in the correct position. So, in order to change the coils you have to remove the connectors.
• Step 5: Now gently pull and twist the ignition coils to free them from the cylinder head.
• Step 6: Lastly, install the new coil in the reverse process.

How To Maintain Ignition Coils?

Following is the list of suggestions that can be used to maintain the coils:

• Avoid the things that could heat up or damp the coils.
• If your engine is not running, don’t turn on the ignition switch.
• To prevent short circuits, you have to check, clean and tighten the circuits regularly.
• You should control the engine performance so that you don’t have to face overvoltage issues.
• If there is moisture on the ignition coils, dry it with clothes. But don’t roast it with fire because it will damage the coils.

Conclusion

To sum up, ignition coils are one of the important parts of the ignition system. You cannot begin to think of powering up the engine without them. However, with passing time they start to fail and make it difficult for you to use your car. So, try to find the right replacement according to the checklist and also follow the installation steps accurately.

Like other Toyota models, Corolla has its own specifications and engine system so whenever you buy an ignition coil, make sure it fits to the car. Lastly, match the replacement part numbers with the original parts so that you can ensure the compatibility of the coils.
