And maybe you need consult 3 to clear this code?

Sorry can't help much as there's not much info out there about this fault.

Also try G37 forums as well.

And in EC.pdf see under contents..

ADDITIONAL SERVICE WHEN REPLACING
CONTROL UNIT (VVEL CONTROL MODULE) .......18

Theres only a handful of threads concerning the P1606 code on both 370z and G37 forums. Im not sure what one relay has to do with another though?

I had waited overnight with the "new" module installed, hoping that the ECU does its thing with updating, but it still had the code. So I put back the original module in with the new relay, hoping perhaps that the module was good, and relay was bad. Ill start her up in a couple hours and keep my fingers crossed.

Its pretty scary driving and all of the sudden the Z goes into limp mode.
