Intended Applications
Primarily fitted to CITROËN C4 I vehicles. The pedal assembly may also be used on other CITROËN or PEUGEOT models that share the same Bosch part numbers—searching by the product codes above is the most reliable method to find matching applications.
How The Part Functions
The accelerator pedal assembly contains a position sensor (potentiometer or hall-effect sensor) that converts pedal travel into an electrical signal for the engine management system. Modern vehicles use this signal for throttle-by-wire control, traction management and cruise control functions. A properly functioning pedal ensures smooth acceleration, predictable throttle response and correct idle behavior.
How To Replace
- Disconnect the vehicle battery before starting work to avoid short circuits and protect electronic modules.
- Remove lower dash or footwell trim panels to access the pedal assembly.
- Unplug the electrical connector and remove mounting screws or bolts securing the pedal bracket.
- Fit the new pedal assembly, secure fasteners to the manufacturer’s recommended torque, and reconnect the electrical plug.
- After installation, check throttle operation with the ignition on (engine off) and perform any required throttle relearn or adaptation procedure using a diagnostic tool if vehicle symptoms persist.
Installation Recommendations
Always follow safety procedures and the vehicle manufacturer’s service manual. Disconnect the battery before removal. Inspect the connector and wiring harness for corrosion or damage and replace or repair as necessary. If the vehicle displays throttle faults or limp-home mode after installation, perform a throttle position adaptation or use a diagnostic scanner to clear fault codes and confirm correct signal readings.
Why This Part Most Commonly Fails
Accelerator pedals typically fail due to internal sensor wear, contamination (dust or moisture ingress), connector corrosion, or mechanical damage from impact or excessive pedal force. Electrical faults and intermittent signals are common symptoms; these can trigger engine warning lights, reduced power modes or erratic idle and acceleration.
Notes For Professionals
Mechanics searching by part number will often find this item listed under Bosch 0280755120 or the Stellantis references provided. When replacing an electronic pedal, verify wiring integrity and module responses before concluding that the pedal is faulty to avoid unnecessary replacements.
