What happens if one ignition coil goes bad?
One of the most common symptoms associated with a faulty ignition coil is engine performance issues. Faulty coils may cause the vehicle to experience misfires, a rough idle, a loss in power and acceleration, and a reduction in gas mileage. In some cases the performance issues may even result in the vehicle stalling.
What causes an ignition coil to burn out?
The main cause of ignition coil burnout is the insulating material aging. For example, when the ignition coil high voltage can’t output smoothly, the current turbulence in coil will occur, causing the temperature to rise rapidly and accelerate the insulating material aging.
How many miles can an ignition coil go?
The ignition coil on your car is supposed to last around 100,000 miles or more. There are a number of factors that can lead to this part become damaged prematurely. Most of the newer cars on the market have a hard plastic cover that is designed to protect the coil from damage.
How do you test a ignition coil connector?
The only safe way to test for spark is to use a spark plug tester tool. If a coil problem is suspected, measure the coil’s primary and secondary resistance with an ohmmeter. If either is out of specifications, the coil needs to be replaced. A coil can be easily bench tested with a digital 10 megaohm impedance ohmmeter.
Are there ignition coil problems on a 2009 Toyota Corolla?
On a 2009 Toyota with less than 50k miles. . . That doesn’t sound, right huh. Well, I took it to a mechanic and they gave me a new battery, an oil change and ran another diagnostic test (after switching the ignition coil (b) to another (acord).
What causes a misfire on a 2009 Corolla?
2009 Corolla Misfire (Ignition coil, ECM?) A couple weeks ago, my check engine light popped on and I noticed my engine misfire. I happened to be driving by an autozone, so I pulled in and had them check the code. Came back as a misfire on cylinder 4, possibly bad ignition coil or clogged injector.

What causes a Toyota ignition coil to burn out?
Coils mainly burn out if the spark plugs are not changed in time and the spark plug gap get too large and then the duty cycle of the coils is increased by the PCM to overcome the extra gap. This duty cycle increase causes the coils to die prematurely…………..SO CHANGE YOUR PLUGS REGULARLY!!
