How to test the ignition coils ( Nissan 1.8L )?
Testing the ignition coils (most commonly known as the COP ignition coils), on your 1.8L Nissan Sentra is pretty easy. You don’t need any expensive diagnostic equipment to see if they have failed and causing the misfire code or condition your Nissan Sentra is currently experiencing.
What happens when one of the ignition coils fails?
The Coil-On-Plug (COP) ignition coils are the ones that create and deliver the Spark that each engine cylinder needs to burn the air/fuel mixture. When one COP ignition coil fails, that cylinder goes ‘dead’ due to a lack of Spark and is said to be misfiring.
How does the PCM activate the ignition coils?
The PCM (Powertrain Control Module = Fuel Injection Computer) gets the crankshaft position signal from the crank sensor. The PCM now activates each COP Ignition Coil.

Can a bad coil pack cause an Altima to misfire?
There is more to your Altima’s ignition system than just the coil packs. There’s also spark plugs and plug wires. There are also non ignition related circumstances that can cause a misfire. That would include lack of fuel pressure, bad fuel injectors, or even a timing chain (or belt) that has jumped.
Can a bad coil pack cause a bad spark plug?
Coil Packs take the place of the distributor and coil in older vehicles. They receive instruction from the engine’s computer on when to fire the spark plugs. The symptoms of bad coil packs are almost the same as bad spark plugs. So much so that it’s actually a better idea to look at the plugs first.
How much does it cost to replace ignition coil?
I’m working on my wife’s 2000 Maxi, with 70,000 miles on it. It had the 0306 code, and a shop told me that the ignition coil should be replaced on number 6 cylinder. They wanted a ridiculous amount of money to do it, including changing all 6 spark plugs, and charging me $28 each for the NGK plugs, and $160 for the coil.
