P2101 on Nissan
Throttle Actuator "A" Control Motor Circuit Range/Performance
P2101 on Nissan vehicles indicates throttle actuator "a" control motor circuit range/performance. Au7o has documented this code across 1 Nissan model — most commonly on Rogue. This powertrain code means the engine computer commanded the electronic throttle actuator motor to a certain position but the motor did not respond within the expected range. Modern engines use a drive-by-wire throttle, where a motor opens and closes the throttle plate based on signals from the computer rather than a cable. When the actual throttle position disagrees with the commanded position, the computer sets this code, often forcing the vehicle into a reduced-power 'limp' mode to protect the engine. This can cause poor acceleration or stalling and should be addressed promptly. Typical repair costs on Nissan range from $100 to $900, depending on the specific model and root cause.
Common Causes of P2101
- •Faulty throttle actuator control motor (throttle body)
- •Dirty or carbon-fouled throttle plate causing binding
- •Wiring or connector problems in the throttle actuator circuit
- •Failed throttle position sensor inside the throttle body
- •Poor electrical connection or corroded terminals
- •Faulty engine control module (less common)
P2101 on Nissan by Model
Nissan Rogue(2 issues)
- Electronic Throttle Body Polymer Gear Fracture Causing Sudden Loss of Power and No-Restart (Recall)2024-2025
The electronic throttle body uses internal polymer gears (chosen for thermal stability at the engine's ~250F operating temperatures). The teeth on these polymer gears can fracture, jamming the throttle valve. This causes sudden loss of power/stalling and, on restart, can prevent the transmission from engaging forward or reverse — creating a rollaway risk. Nissan recall (NHTSA 26V-080-related throttle campaign, ~318,781 units, MY2024-2025 built Nov 13 2023-Apr 28 2025) covers the defect. Over 3,100 warranty claims reported. Separate from the VC-Turbo bearing recall even though both were announced together.
- Throttle Body Carbon Buildup Causing Rough Idle, Hesitation, and Stalling (P2111/P2135)2008-2015
On the naturally-aspirated QR25DE Rogue, carbon and oil grime accumulate inside the electronic throttle body and physically stick the throttle plate, causing rough idle, hesitation, surging, stalling, and a check engine light. P2111 (throttle actuator stuck open) is very commonly triggered by this buildup rather than an electronic failure, so a thorough cleaning is often the first fix; if the internal motor or position sensor has failed, the throttle body is replaced. This is a different mechanism and era from the VC-Turbo polymer-gear fracture recall.

What does P2101 mean on Nissan?▼
P2101 stands for "Throttle Actuator "A" Control Motor Circuit Range/Performance." This powertrain code means the engine computer commanded the electronic throttle actuator motor to a certain position but the motor did not respond within the expected range. Modern engines use a drive-by-wire throttle, where a motor opens and closes the throttle plate based on signals from the computer rather than a cable. When the actual throttle position disagrees with the commanded position, the computer sets this code, often forcing the vehicle into a reduced-power 'limp' mode to protect the engine. This can cause poor acceleration or stalling and should be addressed promptly. On Nissan specifically, this code is documented across 1 model.
What causes P2101 on Nissan vehicles?▼
Common causes on Nissan: Faulty throttle actuator control motor (throttle body), Dirty or carbon-fouled throttle plate causing binding, Wiring or connector problems in the throttle actuator circuit, Failed throttle position sensor inside the throttle body, Poor electrical connection or corroded terminals. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2101 on a Nissan?▼
