What is a throttle body air filter?
The throttle body is the part of the air intake system that controls the amount of air flowing into an engine’s combustion chamber. The throttle body is usually located between the air filter box and the intake manifold, and it is usually located near the mass airflow sensor.
What does the air box do in a car?
An airbox is an empty chamber on the inlet of most combustion engines. It collects air from outside and feeds it to the intake hoses of each cylinder. Older engines drew air directly from the surroundings into each individual carburetor.
What sensor is in the air filter box?
It is installed between the air filter and the intake manifold of the engine. See the diagram. The mass air flow sensor measures the amount of air entering the engine or the air flow. In modern cars, an intake air temperature or IAT sensor is built in the mass air flow sensor.
What is a throttle body and what does it do?
You are here. Home | Tips & Tutorials | Beginner’s Guide: What is a Throttle Body (and What Does it Do)? The throttle body is a tube containing a pivoting flat valve (butterfly) that is used to control the amount of air entering an engine.
Why do you need a good throttle filter?
A good air filter is absolutely critical to the operation of the throttle body, because dirt buildup on its surface over time can gum up the butterfly, causing a rough idle and drivability issues. Depending on how the PCV breather is plumbed on your car’s motor, you may also get a build up of oil residue. How can a throttle body be cleaned?
What makes throttle body sensors sensitive to solvent spray?
Mass Air Flow (MAF) sensors are very sensitive to being contaminated, and have a specific solvent spray just for cleaning them. Other throttle body problems can include faulty Idle Air Control (IAC) valves or Manifold Absolute Pressure (MAP) sensors.
Do you need to clean the throttle butterfly?
Pay particular attention to the throttle butterfly, which is attached with small screws (often staked to the throttle pivot to prevent removal) but you don’t need to remove it to clean it. If the throttle position sensor (TPS) or air flow sensor are on the throttle body, be careful with them.
