The 1,000 RPM limit is the fail-safe for the electronic throttle and that relates to the P2101
If that was my car, I would examine VERY carefully all the wires related to the VVEL system and the throttle bodies. Unplug them and check for corrosion or bent pins, then plug back in.
After that my next step would be to scope the throttle body position sensors, VVEL power/grounds and the VVEL CAN bus to verify a proper signal.
Since most don't have a scope, a multi-meter will allow voltage checks.
If you don't have a good understanding of electricity/meter use, you might want to find mobile tech that has these tools and Nissan/Infiniti experience.
How did you determine the VVEL relay was "blown"?

Thank you, definitively I don't have any knowledge or experience in electric or ohms. That will be a job for another person.
For the relay I read here in the forum about that problem and some people mention to check the VVEL Relay. So when I opened the box and found the Relay I noticed that it was blown. So I though that would have fix all the problems. But it seems the car has more than one issue. Thank you for the codes clarifications.
