Nissan Repair Questions? Ask a Mechanic for Answers ASAP
What is the model of your Nissan.
I cant find a wiring diagram to this. How many wires run to coil?
Sorry but I still haven't been able to find wiring diagrams. I will release your question. Good luck.
Hey there, thanks for the question.
The ICM is not going to be the culprit for a single coil getting hot. The ICM merely is like a switch for the coils.
You need to check your grounds, especially if you have a ground to the transmission or the intake manifold.
I have seen hundreds of coils burn up on altimas from a bat battery ground to the transmission bellhousing.
regardless your issue here is likely a grounding issue.
If you need further assistance let me know, if not just remember to leave a kind rating please.
