I have searched for this but unable to find what i need. I even YouTube'd videos but still don't understand. Can someone please explain how I can test my ignition coil for resistance? My car is giving me code 21 and 34. 34 is knock sensor but I think the ignition coil is what is causing 21 (ignition code) which is also triggering 34 so I am wanting to check the coil for resistance. I have the FSM here and I have my multimeter but I'm unsure what specifically to do. Can someone please walk me through it?
