Description
Bosch accelerator pedal for Citroën Berlingo and Peugeot Partner vehicles.
This Bosch electronic accelerator pedal assembly is a direct-fit replacement for Citroën Berlingo and Peugeot Partner models. Designed for workshop use and experienced DIYers, the unit integrates a precision potentiometer-type throttle position sensor to provide accurate pedal position feedback to the engine management system. The assembly restores smooth throttle response, reduces hesitation, and resolves pedal-sensor related error codes when the original unit has failed.
Technical Information
- Manufacturer: Bosch
- Model: Citroën Berlingo, Peugeot Partner
- Product Codes: 1601T8
- Additional Numbers: 9655467180, 0280755035
Function And Application
The pedal assembly converts the driver’s foot movement into an electrical signal (throttle position) that is sent to the engine control unit. On modern throttle-by-wire systems the pedal has no direct mechanical linkage to the throttle body; instead the ECU calculates throttle opening based on the pedal sensor input. This part is intended as a replacement for original electronic accelerator pedals on compatible Citroën and Peugeot diesel and petrol variants that use this pedal design.
Installation Recommendations
- Park the vehicle on a level surface and disconnect the battery before starting work to avoid short circuits.
- Access the pedal assembly from under the dashboard. Remove any trim panels necessary to reach the mounting bolts and electrical connector.
- Unplug the electrical connector, remove the retaining bolts, and swap the old unit for the new one. Ensure the pedal moves freely and that mounting surfaces are clean.
- Reconnect the connector and battery. Perform throttle adaptation/relearn according to the vehicle manufacturer’s procedure or with an appropriate diagnostic tool. If in doubt, use a diagnostic interface to clear related fault codes and to confirm correct sensor values.
- Check for proper pedal travel and smooth response during a road test before returning the vehicle to service.
Why The Part Fails Most Often
- Wear Of Internal Potentiometer Contacts — Repeated use causes gradual wear or inconsistent resistance readings.
- Moisture Or Corrosion — Water ingress or corrosion of contacts and connectors leads to intermittent signals or failure.
- Electrical Damage — Short circuits, poor grounding, or wiring harness damage can cause sensor faults.
- Mechanical Stress — Physical impacts, improper installation, or binding of the pedal mechanism can impair function.
Symptoms And Troubleshooting
- Unresponsive Or Jerky Throttle Response During Acceleration.
- Illumination Of Engine Warning Light Or Throttle-Related Error Codes.
- Reduced Engine Power Or Limp-Home Mode Triggered By The ECU.
- Intermittent Loss Of Drive-By-Wire Control Or Inconsistent Idle.
