P1606 VVEL issue/code

BlackieChanz · 01-08-2020, 03:19 PM

reviving an old thread but this happened to me twice in a year's time. first time I swapped the module and left it overnight then it started and ran fine for several months. recently it's been happening a couple times a week and luckily I was able to clear the code and restart and it would run fine but yesterday the P1606 popped up and WOULD NOT CLEAR. took a Lyft to a nearby dealership where they had 1 relay left in stock, swapped it in and still nothing. limped it home at 5mph and let it sit overnight and now it runs like nothing ever happened. I'd really like to know the definite fix for this. even though I have AAA I'd rather fix it once and be sure.

tl;dr new relay + sitting overnight fixed my P1606

Check your grounds for vvel. Wire brush and make sure they are tight on the chassis.

My dealer says it's the wiring harness. They wanted 8k between parts and labor. There's 2 harnesses they wanted to replace. The engine harness and the body control harness. Talking to the mechanic himself he said he thinks it's just the body control harness but he had to run it by some area Nissan engineer who told him replacing both is the only way to garuntee it's fixed since I kept coming back with the same issue.
