Description
Accelerator pedal for Citroën C4 and Peugeot 307. With switch for speed limiter. Tested, fully functional – 6.3 kΩ and 372 Ω.
This Bosch accelerator pedal assembly is a direct-fit electrical throttle position unit commonly used on Citroën C4 and Peugeot 307 models. It integrates a dual-channel potentiometer for accurate pedal position feedback and includes a mechanical/electrical switch for the speed limiter/cruise control function. Supplied with original equipment part numbers, it is a frequent search item for workshops and DIY enthusiasts who look up parts by OEM code.
Technical Information
Manufacturer: Bosch
Model: Citroën C4; Peugeot 307
Product Codes: 0280755001
Other Numbers: 9650889180, 1601P3
Function And Key Features
The unit measures the pedal position and converts it into an electrical signal sent to the engine/drive-by-wire system. It contains two potentiometer channels to provide redundancy and signal validation. The integrated switch operates the speed limiter/cruise control input. Measured resistances provided with the unit are approximately 6.3 kΩ and 372 Ω, corresponding to internal potentiometer channels used for position sensing.
Replacement Procedure
1. Park the vehicle on a level surface, engage the handbrake and switch off the ignition.
2. Disconnect the battery before starting work to avoid short circuits and to protect vehicle electronics.
3. Remove the lower dash trim or footwell cover to access the pedal assembly.
4. Unplug the electrical connector and remove any securing clips or bolts holding the pedal to the bracket.
5. Fit the replacement pedal, secure bolts to manufacturer torque where specified, and reconnect the electrical connector.
6. Reinstall trim pieces and reconnect the battery.
7. After installation, read and clear any fault codes. Some vehicles may require a pedal adaptation or throttle relearn procedure; consult vehicle service information for exact steps.
Recommended For Installation
Best performed by a trained technician or an experienced DIYer familiar with electrics and interior trim removal. Use correct hand tools and observe bolt torque specifications where available. Always ensure connectors are fully seated and locking tabs engaged. If fault codes persist after fitment, perform diagnostics with an appropriate diagnostic tool to confirm signal integrity.
Why This Part Fails Most Often
Common failure causes include wear of the potentiometer tracks, contamination from dust or moisture, corrosion or poor contact in the electrical connector, and mechanical wear in the pedal pivot or return spring. Intermittent or incorrect pedal position signals typically result in throttle response issues, limp-home mode or cruise/speed limiter faults.
Notes For Mechanics And DIYers
Searchable by OEM and Bosch numbers (0280755001, 9650889180, 1601P3), this part is often identified by part code during procurement. The presence of dual resistance readings (6.3 kΩ and 372 Ω) can help verify correct sensor channels when bench-testing a unit before fitment. Always clear and monitor fault codes after replacement to confirm correct operation.
