Thread: Code p2101 on QG18de sentra

Been getting this code on a 2006 sentra. Just replaced the TB with a Hitachi replacement factory unit, but still getting code.

The FSM says that either the wiring is bad, or the TB is no good. But since the TB is replaced, I was wondering who else has had this issue pop up or knows a common fix at this point.

Car starts fine. After clearing codes, idle is a bit high. Code gets thrown the first time you press the pedal. The FSM says that the pedal sensor will not throw this code, so I would guess this code is localized to just the TB or wiring. However, I don't want to keep throwing parts at this issue. It could be bad wiring, a bad ecu, bad ground somewhere...

Hopefully this issue is common enough that someone here can help. Google hasn't been helpful.

After replacing the TB, is it absolutely necessary to do the idle relearn immediately to prevent the code? Any info on this issue would be greatly appreciated.

The Dash is the smartest group of guys I've had the pleasure of learning with, so hopefully someone else has run into this issue in the past and can give me some pointers on it.

I guess I should tell you guys the definition of the code.

P2101 Electric throttle control function.

I checked all wiring, relays etc. All checked out good. Nissan covers the computer for 8 years or 80k. My buddy took the car in, and after a little bit of a dealer hissy-fit, they ordered him a new computer.

Computer fixed the issue. Car runs 100% now.

Hopefully google can direct people to this thread if they run into the same issue. Either the TAC motor is bad, wiring, or the ECM is dead. Knowing what I know now, the TAC and computer are most likely the cause for the P2101.
