When is the distributor replaced by the coil pack?
When the energy reaches the spark plugs, it starts the combustion process. In more modern cars today, the distributor is replaced by the coil pack. This is typically because the coil pack is more reliable and consistent than the distributor.
What should ignition resistance be on Honda Accord?
To check the ignition coil, measure the resistance between the + terminal (black/yellow wire) and the – terminal (white/blue wire) of the coil. The resistance should be about 0.6 to 0.8 ohms at 70° F. Then check the resistance between the + terminal (black/yellow wire) and the coil wire terminal. It should be about 12,000 to 19,200 ohms at 70° F.
Why does my Honda Accord not get a spark?
There are three primary things that will keep the engine from getting a spark: A bad ignition coil, a bad igniter, and a bad distributor. To check the ignition coil, measure the resistance between the + terminal (black/yellow wire) and the – terminal (white/blue wire) of the coil.
When did they start putting coil packs in cars?
Coil packs began to be implemented in many vehicles during the late 1990’s. The biggest reason most manufacturers have turned to coil packs is they are more reliable. Many coil packs don’t require service for up to 120,000 to 150,000 miles.
When to know if your Honda Accord has a bad coil pack?
When a Spark Plug is misfiring, it is often most pronounced at idle speed. This is because when the engine turns slower, it is easier to detect. You’ll feel a rough vibration.

A bad oil pack can make your Accord almost un-drivable. Or it may have little effect at all on the engine’s ability to run. It’ll get worse as they lose their ability to fire the spark plugs. 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.
What can cause a Honda Accord to misfire?
There is more to your Accord’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.
What happens if you have a bad coil pack?
Coil Pack Problems Usually, if a coil pack is bad, there will be a loss of fire or spark in one or more cylinders. This causes what’s commonly referred to as misfiring. Misfiring can cause drag on the crankshaft, and usually results in a very poor performing engine.

What happens if the ignition coil does not work?
If your ignition coil does not transmit enough energy to the spark plugs in your car, your vehicle will have to burn and use extra fuel. This is the only way that the vehicle can keep running – by burning the extra and residual fuel.
Which is more reliable wasted spark or single coil?
The wasted spark system consists of one coil generating two sparks per cycle to each cylinder. The fuel within the cylinder can then be ignited. The wasted spark system is more reliable than a single-coil system, and is also less expensive than a coil-on-plug option.
