2005 nissan maxzima when you rweplace the engine control moldule do you have to

Yes, you'll always need to program a control module. It's hard to know the source of your old module, so I can't really say for sure. I also don't know the reason your'e replacing it - rarely does a control module need to be replaced. I'd recommend professional assistance at a shop near you. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
