How does an EFI throttle body work in a car?

Here’s what you need to understand: While a carburetor moves both fuel and air (and must be sized according to engine size and horsepower), an EFI throttle body moves only air, essentially serving as an air door. Fuel delivery is controlled by the electronically operated injectors.

What happens when the throttle body goes bad?

Nowadays there is an electric system that’s far more efficient than the old ways but it can still have issues. When a TPS goes bad, then the car’s throttle body won’t function properly. It could either stay shut or it won’t close properly which is a severe issue. If it stays shut then your engine is not going receive air and it won’t start.

What are the different types of throttle bodies?

Where is the throttle body located in a car?

Typically, in most vehicles, the throttle body can be found in between the intake manifold and the air filter or air cleaner of the engine system. Usually, the aluminum is used for the making of the throttle body. The location of the throttle body can be a little different for different vehicles.

What’s the difference between dry and wet throttle bodies?

Performance Perspectives: EFI Throttle Bodies. A throttle body that incorporates one or more fuel injectors provides both fuel and air and can be referred to as a wet throttle body. A throttle body that serves only to regulate intake air is usually referred to as a dry throttle body.
