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.
What does code 9141 mean on my maxima?
30 people found this helpful. The code 9141 means your code reader isn’t connected properly. 23 people found this helpful. I am puzzled with this Maxima! Recently tuned up with new coil packs, new air flow mass sensor, and plugs! It show code ISO 9141 on scanner and autoxone diagnosed it needs a tune up.
What does code 9141 on autoxone scanner mean?

When to know if your car has a p0302 code?
If there is more than a 10 percent variance, the Check Engine Light will blink or pulse in a steady manner to indicate that a harmful Catalytic Converter misfire is occurring. When diagnosing a P0302 code, it is important to record the freeze frame information and then duplicate the code setting conditions with a test drive.
When does an ignition module need to be replaced?
If the light blinks, the module is good. If the light is blank or constant, the module is bad. Before you attempt to replace the control module, you must rule out other ignition system components. The module is expensive and replacing it is a laborious process. Check the ignition coil for a spark.
What are the symptoms of a bad ignition coil?
These are the symptoms of a bad ignition coil: Misfires – Check Engine Light: Misfiring is usually the first and most common symptom, and in most vehicles today, this will appear as a Check Engine Light. The misfire will either be on a particular cylinder, or random.
What kind of misfire is a check engine light?
Misfires – Check Engine Light: Misfiring is usually the first and most common symptom, and in most vehicles today, this will appear as a Check Engine Light. The misfire will either be on a particular cylinder, or random. Most of the time, specific-cylinder misfires become easier to diagnose than the random-cylinder.
What kind of spark tester is used for ignition coils?
An ignition spark tester like OEM 25069 takes the place of a spark plug – is grounded to the engine and can easily show you whether a particular wire or coil is providing spark.

Where can I test the ignition coils in my car?
It’s easy enough to test your vehicle’s ignition coils yourself with a few tools from your local AutoZone. Even if you get a normal reading, ruling them out as the problem can help you narrow the issue with the ignition system.

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.
How can I tell if my ignition coil is shorted?
Check the reading on the multimeter and compare it to the resistance specifications for both the primary and secondary windings. If the reading falls outside the normal resistance range, you’ll need to replace the ignition coil. A zero means the coil shorted internally.

What should resistance be on a Harley Davidson ignition coil?
Measure the resistance across the two smaller terminals on the coil. The meter should read between 2.5 and 3.1 ohms. Set the ohmmeter to read resistance on the “Rx1000” setting. Measure the resistance across the two larger terminals on the coil. The ohmmeter should read between 10,000 and 12,500 ohms.
What should the resistance be on the rx1000 coil?
The meter should read between 2.5 and 3.1 ohms. Set the ohmmeter to read resistance on the “Rx1000” setting. Measure the resistance across the two larger terminals on the coil. The ohmmeter should read between 10,000 and 12,500 ohms.
What does a 1 ohm reading on an ignition coil mean?
A reading of “1” indicates complete resistance, or no connectivity. This indicates an ignition coil that has failed. Look at the reading on the ohm meter. Ideally, you should see a read-out of 2.5k to 5k ohms, indicating that the coil’s wiring is intact and working correctly.
What should the resistance be on a Harley Davidson ignition coil?
It is important to use the correct electrical manual for your ride. When testing your Harley Davidson ignition coil you will be testing ohms resistance. You will find that the primary resistance will be a low number; 0.5 to 5 ohms, for example.
What do you need to know about ignition coil failure?
Check your high tension leads (HT Leads). They run between the distributor and spark plugs. Ignition coil failures result in 1 or more spark plugs not receiving the appropriate amount of charge. If you have trouble starting your vehicle in the cold, this is a good sign of potential ignition coil failure.
What causes a misfire on a coil on plug?
When the engine cools off overnight, the fuel in the rail cools and condenses, leaving a small pocket of vapor at the highest point in the rail, right next to injector No. 1. Naturally the misfire clears up quickly as the rail fills with fuel, and there’s no reason to chase this problem any further (how could you possibly fix it?).
What’s the difference between dual and single fire coils?
Dual fire coils send spark to both cylinders, all the time. Regardless of which cylinder is on the compression stroke. Single fire coils designate spark to only the cylinder that is on the compression stroke. Spark is delivered to one cylinder at a time. Harley Davidson Ignition Coils are known to fail.
