SET CONDITION
If PCM detects that the secondary ignition burn time is incorrect, to short, or not present, an error is detected. One trip Fault. Three good trips to turn off the MIL.

Drivers side, 3rd coil back. It is a bit of a pain, it is the cyl directly underneath the brake booster. Make sure your connections are good and tight first, it could be a bad connection on you coil wires, or spark plug wires...

I had a bunch of those "Ignition Coil Circuit" codes when I installed the shortie wires. I even ensured that they were pushed all the way down. So I ripped them out and reinstalled my set of long Taylor Thunder Volt 50s. Codes went away.

well i checked all the connections to coil 5, and nothing appeared to be loose. so i guess ill try to turn off the truck, disconnect the neg. battery cable, let it sit, reconnect and turn it on again. see if that does anything. if not, i think ill just let it be cuz the truck drives fine, its def. not misfiring on that cylinder or anything

its your wires. I bet you that you have a wire lose. I used to get this code all the time. Just put your stock wires back on and clear the code and it wont come back again.

I have the stock wires on, never took them off. I replaced the plugs with the same ones that came out from the factory. I will try and switch coil packs to see if that makes a difference. Only happens when a programmer is on there. Weird...

well i switched the shorties around a bit, and i got the code again after about 300 miles. same coil so idk. the truck runs normal so like people said it might just be the wires, programmer idk. oh and the weirdest thing, i had codes for my read 02s cuz im not running cats, so i stuck them under the heat shields. now no codes from them however my front 02s are throwing codes. weird
