Good day,

I have a 2007 Accord SE and I'm trying to find the resistance specs for the Hitachi ignition coils the car has. There are not in my manual and I cannot find online.

Can anyone point me in the right direction? I need the specs to bench test the coils.

Appreciate any input, thanks!!

 

Resistance specs arent a very reliable indicator of a components health. As such those specs have mostly gone away......

 

Good morning, appreciate your reply. Wasn't aware of that.

I've seen a few videos where they say to start the engine and then disconnect each coil and listen for a change in how the cars running to determine if the coil is bad. Is that a good test? The car is running a little rough at idle and idling a little high as well. The engine noise also seems a little louder. The car used to be very quiet, but when my daughter pulls into the drive way and stops, it sounds louder than it used to be, a deeper base sound if that makes sense. When you put the car in reverse after starting you don't even have to put your foot on the gas, the car just wants to take off. The car has 150K miles with new plugs 1 year ago. Starter, Alternator and battery are all newer too. Trying to teach myself how to do some car work as I can't really afford to take it to the garage. Since it's running rough at idle and the plugs are new, thought I should check out the coils. I have the OEM manual to help me. Once the car warms up she runs fine.

 

When a coil fails you'll know it.

It will run extremely rough, have low power and the check engine light will either flash or come on solid.
