The throttle body in your INFINITI G37 is responsible for monitoring and controlling the amount of air that flows into your engine's combustion chamber. Without it, your car or SUV's engine would be starved of one of the elements it needs most to produce the power you rely on.

How A Throttle Body Works

The largest, and most essential, part of the throttle body is the throttle plate. Most vehicles have just one, but some boast more to boost throttle response. The throttle plate features a butterfly valve that rotates on a shaft. When you press and release the accelerator pedal, the shaft rotates the valve and causes air flows into and out of the engine. That helps to keep your vehicle running at the desired speed.

Other parts of the throttle body include the housing, a barrel valve, and a side valve.

How to Spot Throttle Body Problems

Even the best throttle body parts can go bad due to wear and tear, electrical shorts, or broken wires. Signs of trouble include:

  • Poor fuel efficiency
  • Worsening acceleration
  • Unusual engine idle speeds
