How to test the ignition coils on a Honda Civic?
You don’t need any expensive or exotic diagnostic tools to diagnose a bad ignition coil on your 2001-2005 1.7L Honda Civic. The most important tool that you’re gonna’ need, to test the ignition coils for spark, is a spark tester.
What is the primary resistance of a Honda ignition coil?
So I measured the primary resistance between the coil (+) & (-) terminals and got 0.22 ohms, which I think is too low. Checking the secondary resistance between the coil tower (including the spark plug wire because it’s all one piece) and the (+) terminal I got 10 K ohms, which I think is okay.
What happens if you have a bad coil pack on a Honda Civic?
Bad Coil Packs are one of the more problematic ignition issues that can occur with the Honda Civic. A bad oil pack can make your Civic 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.
Can a Honda Accord ignition coil go bad?
CASE 3: You got NO spark from none of the Honda Accord’s (or Odyssey’s) Coil-On-Plug ignition coils. It is rare (next to impossible) for all of the ignition coils to go bad at the exact same time.

What can cause a Honda Civic to misfire?
There is more to your Civic’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 ignition coil cause a Honda to not start?
Extended cranking time (hard start). If more than one ignition coil is bad, your Honda won’t start. If your Honda is experiencing any of the above symptoms, chances are that you do have a bad COP coil on your hands. Let’s take a look at some of the basic tools you’ll need to diagnose and repair this yourself.
What do you call a bad ignition coil?
These ignition coils are known technically as Coil-On-Plug (COP) ignition coils. If you suspect that your Honda has a bad COP ignition coil that’s causing a misfire condition (and setting a misfire code that is lighting the check engine light (CEL)), then this is the tutorial you need. Contents of this tutorial: Symptoms Of A Bad Ignition Coil.
Do you need spark tester for Honda Civic?
This is why a spark tester becomes a must have tool. To get the ignition coil diagnostic going, the first thing that needs to be done is to find out which cylinder is misfiring. This usually means hooking up a scan tool (or a code reader) to your Honda Civic and checking for misfire trouble codes.
How to test the no spark ignition coil?
TEST 1: Checking For Misfire Codes. TEST 2: Check The Ignition Coil For Spark. TEST 3: Swap The ‘No Spark’ COP Coil. Spark Plug Tube Seals Leaking Engine Oil. Where To Buy The COP Ignition Coils.
What should I do if my Honda Civic is misfiring?
To get the ignition coil diagnostic going, the first thing that needs to be done is to find out which cylinder is misfiring. This usually means hooking up a scan tool (or a code reader) to your Honda Civic and checking for misfire trouble codes.
How can I tell if my ignition coils are working?
Different coils will have different touch-points depending on how the coil is designed. Your repair manual, or online information should tell you exactly where and which pins to touch off to. Check the reading on the multimeter and compare it to the resistance specifications for both the primary and secondary windings.
Can a faulty ignition coil keep a car from running?
A completely faulty ignition coil can often keep the vehicle, especially a 4 cylinder vehicle, from running at all. If you’re having an ignition coil issue, you’ll want to test your coils to determine which one is having problems. Follow these steps to test an ignition coil.
Where does the voltage go in an ignition coil?
Depending on the type of coil you have, this voltage either travels from the single ignition coil into a distributor, from the coil itself into a spark plug wire, or in the case of Coil-On-Plug (COP) systems, the coil sits directly on top of the spark plug.
What is the misfire code on ignition coils?
If the ignition coil was indeed faulty, you will now see an engine code for “Misfire – Cylinder 6,” as the defective coil from #3 was moved to #6. Your next step is to pull the #6 coil you just moved and replace.
Which is the best spark plug for a Honda Civic?
NGK 2477 is the best spark plugs for Honda Civic 1992-2000. These spark plugs feature a special fine wire iridium center electrode and taper cut ground electrode for maximum ignite ability and performance. These spark plugs still have a copper core electrode and the iridium is in the tip of the plug.
How often should I change the spark plug in my Honda Civic?
In general, it’d be better if you get a new spark plug installed after every 30 000 miles, however, it depends on the material, which was used for a spark plug production. Thus, iridium ones last the longest – up to 100 000 miles.

What kind of ignition coil does a Honda CRV use?
The BWD P-Series HEI ignition coils use high efficiency laminations to optimize magnetic field build-up, to produce high spark energy. After diagnosing a no spark condition on a 1997 Honda crv, had it running in 10 minutes with this replacement ignition coil.
What to do if your Honda Civic has no spark?
Now, with no spark in any of the engine cylinders, this what I would suggest: Check for spark directly on the ignition coil tower using a spark tester. This is the best way to test the distributor cap.
Why does my Honda Civic not start up?
I’ve found that most of the ‘cranks but does not start’ problems I’ve diagnosed and repaired on Honda Civics, have had their root cause in the ignition system. Specifically the ignition system is not creating Spark. So, my recommendation to you, is to test each spark plug wire with a dedicated spark tester.
Extended cranking time (hard start). If more than one ignition coil is bad, your Honda won’t start. If your Honda is experiencing any of the above symptoms, chances are that you do have a bad COP coil on your hands.

Is there a pulse generator for the pickup coil?
There is the stator and the pickup coil (pulse generator). To test the pulse (trigger to tell the computer when to send ignition to the spark plug) the motor needs to be turning over. I removed the stator. Now I just wanna make sure I check it correctly.

What should the peak voltage be on a stator coil?
Welcome to the forum. Thanks, I did order one but its not in yet. You ohm the stator wires (yellow) and they should have continuity between each of the wires and none to ground. You need a peak voltage tester to check the pulse generator (blue/yellow wire + and green/white wire -) and the peak voltage is 0.7V.
