Bosch Electronic Throttle Body Assembly

The Bosch Electronic Throttle Body Assembly (also called a drive-by-wire throttle body or electronic throttle control unit) regulates the amount of air entering the engine. It responds to commands from the engine control unit (ECU) and the accelerator pedal position sensor. This gives precise airflow control for smooth throttle response, steady idle, and efficient fuel metering.

Key Features:

• Electronic throttle actuation: an integrated motor positions the throttle plate based on ECU input, with no mechanical throttle cable.
• Built-in position sensors: they give the ECU accurate throttle angle feedback for correct air-fuel mixture control.
• OE-quality engineering: Bosch is a leading original equipment supplier of fuel injection and engine management components.
• Precision-machined housing and throttle plate: these help ensure consistent airflow and reliable sealing.
• Assembled and tested: each unit is built as a complete assembly for dependable operation.

A worn, dirty, or failing throttle body can cause rough idle, hesitation, stalling, reduced power, or a check engine light. Replacing it with a Bosch assembly helps restore smooth drivability and engine performance. Select the correct part number for your application from the available options in this product line.
