What is the cost of a mother board replacement for a 2001 Infiniti
Engine light is on. Was told the mother board needs to be replaced. What can I
anticipate as the cost for this repair and the time frame to repair?
What the garage is telling you is the cars computer module or PCM/ECM is faulty. If you buy a new one it will cost more than a used one. I'd have the garage find a used one from an auto recycler. Install procedure is to remove a plug on the end and reinstall, the hard part is removing panels to access it.
