Acura MDX Throttle Body

The V6 engine of the Acura MDX gets a readily available air supply thanks to the Throttle Body. Throttle response is crisp and fuel economy is balanced. Positioned between the air filter housing and the intake manifold is a Throttle Body. It consists of a butterfly plate that opens and closes in accordance with the accelerator pedal position. The Powertrain Control Module (PCM) modulates fuel injector pulse width to attain the correct air fuel ratio. The earlier MDX generations had a plate that connected to the cable. The later MDX versions switched to electronic throttle control. Electronic throttle control is a drive by wire setup. It has an electric motor that replaces the mechanical linkage. Furthermore, the motor is commanded by pedal position sensors. This makes for a much smoother throttle input. It also allows for the addition of traction and stability features. Regardless of the version, sensors like the throttle position sensor and an idle bypass port connected to an idle air control valve allow the computer to fine-tune idle speed. Over mileage, wear and tear of the shaft and carbon deposits in the Throttle Body can cause rough running. Periodic cleaning of the Throttle Body will make it functional again. For each MDX, multi port injection is applied. This means fuel is delivered in the intake runners and not in the Throttle Body. This is different from body injection units and helps Acura buyers. The current Acura design keeps the aluminum housing light yet strong.

We provide a broad range of OEM Acura MDX Throttle Body at unbeatable prices on our website. For your OEM parts, You can count on the guaranteed quality, manufacturer's warranty, outstanding customer service, and prompt delivery. We look forward to your visit.
