Reason why aftermarket coils throw codes. Enjoy

Part 1. Here's some analysis from one of my Nissan clubs about problems that come with aftermarket coils.

NOTE: Postings following these videos indicate this can happen to Toyota also. These videos go into detail about the "havoc" that can be brought to your cars ignition and fuel delivery system when you aren't using Denso, Aisin, Aisan, and NGK parts that are from OEM from reputable sources.

Like Toyota, Nissans are extremely picky, about OEM components from Hitachi, JECS, Hansin, and NGK.

Another mention from the video that I've learned through the years is a healthy charging system (e.g. battery and alternator) help keep the ignition system happy and performing optimally. Its all connected.

aftermarket ignition coils in newer toyotas can cause the weird problem of killing spark all together... never will buy aftermarket UNLESS its genuine denso..

 

Absolutely! Its amazing how many nice looking cars that I've seen in junk yards with easily recognizable aftermarket control system parts. I can just see where the owner gave up and traded the car off to a dealer that auctioned the car off to a scrap yard. Then I have my 30 year old car that I've kept OEM and it just keeps on running.

 

people just need to know you cant skimp on some stuff!
