• Description:

  Rough idle, stalling, or poor acceleration? Restore smooth engine response and precise airflow control with the OEM Nissan Throttle Body (Part #16119-9NT0C), engineered to maintain accurate throttle position and optimal fuel delivery.

  Throttle Body (16119-9NT0C) – OEM Replacement Part for Nissan

  This genuine Nissan throttle body regulates the volume of air entering the engine, allowing the ECM to balance fuel mixture and maintain smooth idle and acceleration. Over time, carbon buildup or electronic wear can reduce response and trigger performance codes. Installing an OEM throttle body ensures correct airflow calibration, consistent idle speed, and proper throttle response.

  Specifications

  • Part Type: Electronic Throttle Body Assembly

  • Function: Controls intake air volume via electronic throttle control (ETC)

  • Construction: OEM-grade aluminum housing with factory-calibrated motor and TPS sensor

  • Position: Mounted between air-intake duct and intake manifold

  • Includes: Complete electronic throttle body unit with integrated sensors

  Compatible Nissan Models

  • 2015 – 2025 Nissan Maxima (A36US)

  • 2012 – 2021 Nissan Pathfinder (R52US)

  Key Features

  • Genuine Nissan OEM part ensures exact voltage range and calibration with ECM

  • Restores smooth idle, acceleration, and throttle response

  • Factory-tested electronic motor and position sensor for precise control

  • Die-cast aluminum housing resists heat and carbon deposits

  • Plug-and-play fit — no wiring modifications required

  Important Installation Notes

  • Always perform an ECM idle air-volume learn procedure after installing the throttle body; skipping this step may cause rough idle or high RPM.

  • Clean the throttle bore and intake air ducts before installation to prevent contamination.

  • Some vehicles may require ECM reprogramming or throttle relearn based on service bulletins.

  • Use only Nissan-approved gasket materials and torque values to ensure proper sealing.

  If unsure, consult the factory service procedure or have installation completed by a certified technician.

  Failing to Replace a Faulty Throttle Body Can Lead To:

  • Check Engine Light (CEL): Common codes include P2101, P2119, or P0507

  • Unstable Idle or Stalling: Improper air control at low RPM

  • Reduced Acceleration or “Limp Mode”: ECM limits throttle for safety

  • Poor Fuel Economy: Unbalanced air-fuel mixture

  • Failed Emissions Test: Due to incorrect idle speed control

  Related Components to Inspect or Replace

  • Throttle Body Gasket (16175-xxxx): Replace any time the throttle body is removed

  • Mass Air Flow Sensor (22680-series): Clean or replace if airflow codes persist

  • Intake Manifold Gasket: Inspect for air leaks near throttle mounting surface

  • PCV Valve: Check for restriction affecting idle control

  • Air Filter: Replace to maintain proper airflow

  Order with Confidence

  Order the OEM Nissan Throttle Body (16119-9NT0C) to restore factory-smooth engine performance and responsiveness. Genuine Nissan throttle bodies ensure correct sensor feedback and idle control for long-term reliability.

  Throttle Body & Airflow FAQ

  Q: Do I need to perform a throttle relearn after installing this part?
  A: Yes — an ECM idle air-volume learn is required to sync the new unit with the vehicle’s computer.

  Q: Can I clean and reuse the old throttle body?
  A: Minor carbon build-up can be cleaned, but worn motors or position sensors require replacement.

  Q: Do I need to reprogram the ECM?
  A: Some models may require an update — refer to Nissan service instructions for your VIN.

  Q: Should I disconnect the battery during installation?
  A: Yes, disconnect the negative terminal before removal to avoid ECM faults.
