Overview

This throttle body housing is a direct-fit part for the 1.0 1KR engines used in Citroën C1 and Peugeot 107 models. Built to replace the OE unit identified by part numbers 0280750481 and 22030-0Q020, it restores proper airflow control, throttle response and idle stability. Ideal for professional workshops and DIY mechanics looking for a reliable replacement during routine maintenance or when diagnosing drivability issues.

Features And Function

• Controls intake air flow into the engine by housing the throttle plate and associated sensors/actuator.
• Essential for idle control, throttle response and engine load management.
• Designed to mate with existing intake hoses and sensors on the 1KR engine family; hoses are not included.

Compatibility And Applications

Primary fitment: Citroën C1 and Peugeot 107 with 1.0 1KR engines. Commonly referenced by OE/product numbers 0280750481 and 22030-0Q020 and additional identifiers 163617 and 163645. Always verify the part number listed for your vehicle chassis and engine code when replacing the throttle body.

Common Symptoms Indicating Replacement

• Rough or unstable idle, especially after cold start.
• Loss of engine power or poor throttle response.
• Check Engine Light with related throttle/airflow fault codes.
• Stalling at low speeds or hesitation under load.

Reasons For Failure

• Carbon and oil deposits on the throttle plate and bore causing restricted movement or incorrect position feedback.
• Wear or failure of internal sensors/actuators (potentiometer/stepper motor) leading to incorrect throttle position readings.
• Vacuum leaks or damaged intake hoses that affect airflow and force the throttle to compensate.
• Electrical issues such as damaged wiring or connector corrosion.

Replacement Interval And Maintenance

There is no fixed replacement interval for a throttle body; lifespan depends on driving conditions and maintenance. Inspect and clean the throttle bore during major services (for example every 30,000–60,000 km) or when drivability symptoms appear. If cleaning does not restore proper function, replacement is recommended.

Installation Recommendations

• Always disconnect the battery before starting work and follow the vehicle manufacturer’s instructions to avoid damage to electronic components.
• Remove intake hoses and electrical connectors to access the throttle body. Unbolt the unit from the intake manifold, transfer any required gaskets or seals, and replace with new ones if damaged.
• Do not overtighten mounting bolts; tighten to the manufacturer’s torque specifications.
• Replace intake hose clamps and inspect hoses for cracks or leaks. Hoses are not included with this part and should be checked separately.
• After installation, perform the required throttle adaptation/idle relearn procedure with an appropriate diagnostic tool (many PSA vehicles require a relearn step). If you do not have the correct diagnostic equipment, have the adaptation carried out by a trained technician.

Why Choose This Part

This throttle body housing is supplied to match common OE reference numbers used on 1.0 1KR installations. It provides a cost-effective and straightforward replacement for workshops and competent DIYers restoring proper airflow control and drivability. When replacing the throttle body, also check the intake tract and perform a throttle adaptation to ensure optimal performance.

Installation Tips For Professionals

• Use a clean workspace and avoid introducing debris into the intake while the throttle body is removed.
• If fault codes persist after replacement, inspect wiring, connectors and vacuum lines before replacing additional components.
• Consider replacing the intake gasket and checking the air filter and PCV system for excessive oil contamination, which accelerates throttle bore fouling.
