How does the ignition coil work on a Nissan Altima?
The Nissan Altima ignition coil bears the crucial operational task of powering the spark plugs in the engine by converting the battery’s current-which is high amp but low voltage-into a high-voltage, low-amp current. Over time, this constant exposure to high-voltage wears down the connections in the coil, necessitating a replacement.
How to remove spark plug from Nissan Altima?
Press the release tab on the grey plastic electrical connector and slide the plug straight off the ignition coil. Loosen the single bolt that holds the ignition coil in place by turning it counterclockwise with a 10mm socket and 1/4″ drive ratcheting wrench. Set the bolt aside in a safe place.
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.
