I have 0-1 ohms resistance from the TB to the ECM. Nearly perfect connection. I see voltage, but it is too low with the CEL on. I get a command for full throttle when the pedal is depressed, but the limp mode keeps the TPS at around 5%

Ok guys. Nissan covers the ECM for 8 years or 80k miles. Took the car to the dealer, they changed the computer, and now everything is good.

Hopefully if anyone runs into this issue, they can reference this thread under a search. If you get a code P2101, the Throttle body is bad or the computer is most likely the issue. Wiring issues are extremely rare without previous vehicle trama. Nevertheless, the problem is solved.

Thanks to everyone contributing to this thread.

glad youve resolved your issue! make sure your battery terminals are always tight and has good contact, check your battery voltage motor on & off occasionally.
