The throttle body is a critical actuator in the engine management system, often called the engine's "throat." Its main functions include:
Controlling Air Intake: Based on the driver's accelerator pedal input (signals sent to the ECU), the ECU commands the throttle body to open or close, precisely regulating the amount of air entering the engine's combustion chambers.
Regulating Air-Fuel Ratio: The amount of air intake directly determines the fuel injectors' pulse width, thereby creating the optimal air-fuel mixture (14.7:1 stoichiometric ratio) for efficient combustion.
Managing Idle Speed: When the vehicle is idling (accelerator pedal fully released), the ECU maintains a very small throttle opening to keep the engine running smoothly without stalling.
Affecting Performance & Fuel Economy: The throttle body's response speed and opening accuracy directly impact acceleration performance, power delivery smoothness, and fuel economy.
When this throttle body fails or becomes excessively dirty with carbon deposits, the vehicle will commonly exhibit one or more of the following symptoms:
Rough or Unstable Idle: The engine RPM fluctuates up and down while stationary, accompanied by noticeable shaking/vibration.
Hard Starting: Difficulty starting the engine, either when cold or warm.
Lack of Power / Hesitation: Sluggish response when accelerating, accompanied by jerking or stumbling.
Increased Fuel Consumption: Inaccurate air metering leads to increased fuel injection, reducing fuel efficiency.
Check Engine Light (CEL): The ECU illuminates the warning light on the dashboard upon detecting a throttle position sensor fault or implausible signal.
Stalling at Idle: The engine may unexpectedly shut off when stopping at a light or coming to a temporary stop.
Please Note: The part number is the ultimate reference for cross-referencing. The list below is based on common applications for this part number but is not exhaustive. Always verify the original part number on your vehicle to ensure 100% compatibility.
