Description
Throttle Body For 1.0 1KR Engines Of CITROËN C1 And PEUGEOT 107. Throttle Body Housing. Hoses Are Not Included.
This electronic throttle body is a direct-fit unit for the 1.0 1KR engine used in Citroën C1 and Peugeot 107 models. Designed to restore precise air metering and stable idle, it is often sought by part number (0280750481 / 22030-0Q020 / 163617 / 163645), which makes finding the correct replacement quick for professional garages and DIY mechanics. The unit controls throttle opening via an actuator and position sensor (drive-by-wire), ensuring correct air supply for combustion and idle control.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C1, Peugeot 107 (1.0 1KR)
- Product Codes: 0280750481, 22030-0Q020
- Additional Numbers: 163617, 163645
Function And Symptoms
The throttle body regulates the amount of air entering the engine according to commands from the engine control unit. It contains an actuator and a position sensor that provide feedback for precise throttle control. Common symptoms of a faulty throttle body include unstable idle, hesitation or poor throttle response, stalling at low speed, increased fuel consumption and illumination of the engine management warning light (throttle/airflow related fault codes).
Installation Recommendations
- Before starting work, disconnect the negative battery terminal to avoid electrical damage and follow the vehicle manufacturer’s safety procedure.
- Remove the air intake hose and associated clamps to access the throttle body. Note: hoses are not included with this unit and should be inspected for wear.
- Unplug the electrical connector(s) and remove the mounting bolts. Keep the mating surface clean and remove old gasket material.
- Fit the new throttle body using a new gasket if required. Tighten bolts to the manufacturer’s torque specification.
- Reconnect the wiring and intake hoses. Reconnect the battery.
- After installation, a throttle adaptation or relearn procedure may be necessary. This can often be completed by a diagnostic tool or by following the vehicle-specific drive/relearn routine described by the manufacturer.
- Inspect electrical connectors and wiring for corrosion or damage; replace brittle intake hoses to prevent vacuum leaks.
Why This Part Most Often Fails
- Carbon and soot buildup on the throttle plate and bore, causing sticking or inaccurate position feedback.
- Wear or failure of the internal actuator or position sensor (electrical faults), causing loss of control or incorrect readings to the ECU.
- Contamination from oil vapors or moisture, leading to corrosion of sensors or electronic components.
- Damaged or leaking intake hoses and vacuum lines (not included), which change airflow and cause incorrect throttle behavior.
- Mechanical impact or improper handling during previous repairs.
Part numbers are commonly used when searching (0280750481, 22030-0Q020, 163617, 163645). Suitable for professional workshops and experienced DIYers who perform careful diagnostics and follow proper installation and adaptation procedures.
