P2101 on Nissan by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Rough or high idle
- Hesitation on acceleration
- Stalling at stops
- Check engine light (P2111/P2135)
- Surging idle
How to Fix
Remove and thoroughly clean the throttle body/plate with throttle-body cleaner, then perform the mandatory Idle Air Volume Learning (idle relearn) procedure to prevent high/unstable idle. If cleaning doesn't resolve it, replace the electronic throttle body and relearn idle. Also inspect for vacuum leaks and a dirty MAF that can mimic the symptoms.
What you need to fix it
Only diagnosis- and fitment-reviewed repair parts are linked here.
- CRC Throttle Body and Air-Intake Cleaner 05078
Universal consumable. Use only as directed on the label and exact Nissan service procedure; not MAF cleaner and not proof that deposits caused the fault.
- CRC Mass Air Flow Sensor Cleaner 05110
Do not substitute throttle-body or carburetor cleaner on the sensing element and do not replace the MAF without test evidence.
- Genuine Nissan throttle-body gasket 16175-ET80A
Cataloged for 2008-2015 Rogue/Rogue Select QR25DE applications; confirm VIN and current supersession.
- Genuine Nissan throttle body 16119-JA00A
2008-2010 Rogue S35 2.5L QR25DE by the inspected catalog branch; confirm VIN and supersession.
- Genuine Nissan throttle body 16119-JA00B
Confirm VIN; this is not the redesigned T32 part.
- Genuine Nissan throttle body 16119-3TA0A
Confirm VIN and perform required learn procedures.

The electronic throttle body uses internal polymer gears. During each ignition start-up the throttle chamber runs a diagnostic that drives the gear against a fixed stopper; ECM software introduced at the start of MY2024 production lengthened that contact, and the repeated loading can fracture the gear teeth, jamming the throttle valve. This causes sudden loss of power/stalling and, on restart, can prevent the transmission from engaging forward or reverse, increasing the risk of a crash. Nissan recall (NHTSA 26V-081, ~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.
Common Symptoms
- Sudden loss of engine power
- Stalling
- Engine will not restart
- Cannot shift into drive or reverse
- Reduced-power / limp mode warning
- Check engine light
How to Fix
Check VIN against the Nissan throttle-body recall. Dealers reprogram the ECM software and inspect/replace the electronic throttle body assembly free of charge. If the vehicle stalls and will not restart or will not shift into gear, do not leave it unattended without securing it; arrange towing to a dealer.

Frequently asked questions
What does P2101 mean on a 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 it is documented across 1 model: Rogue.
What are the most common causes of P2101?
The most common causes of P2101 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P2101 on a Nissan?
Published repair estimates on Nissan range from $100 to $900 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
