Description
Throttle pedal for Citroën, Peugeot and DS vehicles. It is from Citroën C4 II.
This Bosch accelerator pedal assembly (part number 0280755164) is a direct-fit electronic throttle/accelerator pedal designed for a range of PSA/Stellantis models including Citroën C4 II, DS4 and Peugeot 308. The unit integrates an accelerator pedal with a position sensor (potentiometer-type sensor) that communicates pedal position to the engine control unit (ECU). Ideal for professional workshops and DIY mechanics, this replacement restores precise throttle response, eliminates erratic acceleration and resolves pedal-related limp-home modes when the original sensor or connector has failed.
Technical Information
- Manufacturer: Bosch (Supplied To Stellantis)
- Model: Citroën C4 II; DS4; Peugeot 308 (selected versions)
- Product Codes: 0280755164
- Other Numbers: 9671840280, 1601CQ, 1601.CQ, 280755164
Key Features And Benefits
- Electronic accelerator pedal with integrated position sensor for precise throttle control.
- OEM-quality Bosch design and fitment for direct replacement on compatible PSA vehicles.
- Restores smooth and predictable acceleration, reducing hesitation and eliminating pedal-related warning lights.
- Plug-and-play electrical connector and mounting pattern for straightforward installation.
Installation Recommendations
- Work Safely: Disconnect the negative battery terminal before starting to avoid accidental ECU inputs and airbag system faults.
- Access: Remove lower dash trim or footwell covers to access the pedal assembly and electrical connector.
- Disconnect: Unplug the electrical connector and remove the retaining bolts securing the pedal assembly to the mounting bracket.
- Fitment: Install the new pedal assembly in the correct orientation, tighten fasteners securely (follow factory torque specs if available) and reconnect the electrical connector.
- Post-Installation: Reconnect the battery. Some vehicles may require a throttle/idle relearn or ECU initialization—start the engine and allow the ECU to complete its adaptation routine or consult workshop procedures for electronic throttle calibration.
- Inspection: Check wiring and connector for corrosion or damage and ensure pedal moves freely without obstruction.
Why This Part Most Commonly Fails
Accelerator pedal position sensors fail most often due to internal wear of the sensor elements, contamination or moisture ingress in the connector area, and mechanical stress from heavy or improper use. Electrical issues such as corroded pins, broken wires at the harness entry, or intermittent connector contact can also produce erratic pedal signals. Over time, the potentiometer or hall-effect sensing components can drift, causing inconsistent throttle response or triggering engine warning lights and limp modes.
Symptoms Of A Faulty Pedal
- Check Engine Light or throttle warning lamp illuminated.
- Intermittent or delayed throttle response and hesitation under acceleration.
- Limp-home mode with reduced engine power.
- Unstable idle or unexpected engine surges when the pedal is released.
Replacing the accelerator pedal assembly with the correct Bosch part number listed above typically resolves these symptoms. For professional results, follow manufacturer procedures for handling electrical connectors and ECU adaptation after replacement.
