Going to pop it in this weekend. Do I need to reprogram the module or do anything else with it besides plug and play? It is coming from a used car so I wouldn't imagine needing to. Super frustrating.

Will report back once it's done.

Its plug and play. Youll have to reset the ECU, idle relearn, etc..
Make sure the relay box sits securely on the relay box bracket and it doesnt have too much play in it, and also, the little clips on the side that holds the relays make sure they arent broken. That can cause the relays to jar loose.

Just wanted to give an update. So after spending 15 minutes swapping out the VVEL control module with the one I got from ebay for $60, I did a full ECU reset and fired it up. Lights off and the problem hasn't come back for about a month now, ~500 miles.

Hello all, pleased to meet you.

Ive been rebuilding a salvage 2014 Nissan 370Z for the past year and it's just about done. Ive been following this thread for about a month but now that Im authorized I can chime in. I have 4 codes (P1606, U1024, P0112, P0102) as well as many other minor hiccups with drivability, but those are simply a matter of turning a wrench.

The car was running OK with no engine lights until about a week ago when it died at a left turn redlight on the highway... super limp mode was engaged... After getting it off to the side and letting it sit for less than 15 minutes it started up with no problems. No engine light. Ive replaced my VVEL module previously and recently replaced my VVEL relay.

I have a working theory that the issue isn't the VVEL module or relays at all but is in fact the IPDM module supplying inconsistent power to the VVEL module and destroying the components. Im going to go over my IPDM with a multimeter if replacing the relays and VVEL module again (+ better waterproofing) doesnt work.
