Cardone 6E-2003 Fuel Injection Throttle Body

Cardone 6E-2003 New Fuel Injection Throttle Body

Cardone 6E-2003 is a 100% new electronic throttle body built for direct replacement on select Honda Civic applications. It is engineered to match the original design, regulate incoming air through the throttle plate and integrated sensors, and restore proper throttle control after a failed unit.

Fits 2006-2011 Honda Civic, N/A. This Cardone New Fuel Injection Throttle Body is built and tested as a complete assembly for straightforward replacement on the listed Civic applications.

Key Features

• Engineered to match O.E. throttle body design
• Complete assembly built and tested before shipment
• Integrated motor and position sensors for electronic air control
• Direct replacement with no vehicle modification required
• Application-specific calibration and airflow characteristics
• Part number 6E-2003 for accurate catalog matching

How This Throttle Body Works

The throttle body is a powertrain component that uses a plate, motor, and integrated position sensors to control how much air enters the engine. On electronic throttle systems, the powertrain control module or throttle actuator control module commands the throttle valve to the required angle for idle, acceleration, cruise control, traction control, stability control, and other torque-management functions. Cardone 6E-2003 is built to follow the original equipment design so the engine receives the correct airflow across driving conditions.

When an electronic throttle body fails, the warning lamp may illuminate and the system can enter fail-safe mode, reducing engine speed to idle. This replacement is intended for 2006-2011 Honda Civic models listed in the fitment data and is also referenced by part numbers 16400RNAA01 and 16400RNBA01 for the same application.

Common Problems This Part Can Address

• Throttle response issues caused by a worn electronic throttle body
• Check engine light related to throttle position sensor faults
• Idle instability or reduced engine speed after throttle control failure
• Fail-safe or limp-mode operation triggered by throttle system errors
• Airflow control problems affecting acceleration and drivability

Installation Notes

• No vehicle modification is required for installation.
• A relearn calibration procedure is required after replacement.
• Do not install a larger-bore throttle body; this unit is application-specific.
• Do not use a throttle body spacer with this application.
• If the original unit uses coolant hoses, follow the OE routing instructions provided with the replacement; bypassing the hoses is not recommended.

Quality Assurance

Cardone’s New Fuel Injection Throttle Body line is built to proprietary engineering standards and tested as a complete assembly to help ensure proper fit and function.
