Description
Throttle Pedal for Citroën, Peugeot and DS Vehicles
High-quality Bosch throttle pedal assembly (part number 0280755164) compatible with selected Citroën, Peugeot and DS models. This accelerator pedal module integrates the electronic throttle position sensing element (potentiometer/accelerator position sensor) with the mechanical pedal support to ensure precise throttle response, reliability and easy replacement. Ideal for professional mechanics and experienced DIY enthusiasts looking for a direct-fit replacement often searched by part number.
Function And Application
The accelerator pedal assembly measures pedal travel and converts it into an electrical signal for the engine management system. Modern drive-by-wire systems rely on a precise, repeatable signal from the pedal sensor; a faulty pedal can trigger limp-home mode, throttle hesitation or error codes. This unit is manufactured by Bosch for Stellantis platforms and is commonly fitted to models from Citroën, Peugeot and DS.

How It Is Replaced
- Disconnect the negative terminal of the battery and wait a few minutes to ensure systems are powered down.
- Remove the lower dashboard trim or footwell cover to access the pedal assembly.
- Unplug the electrical connector from the pedal module (handle clips carefully to avoid damage).
- Unscrew the pedal mounting bolts and remove the old assembly.
- Fit the new pedal assembly, tighten mounting bolts to the manufacturer torque specification and reconnect the electrical connector.
- Reconnect the battery, clear any fault codes and perform throttle/pedal adaptation using a diagnostic tool if required.
- Verify correct operation with engine running and test drive to confirm throttle response and absence of warning lights.
Installation Recommendations
- Always disconnect the battery before starting work to avoid electrical damage and ensure safety.
- Inspect the connector and wiring harness for corrosion or damage; repair or replace wiring as necessary to prevent intermittent faults.
- Avoid pulling on wires — release connector latches and use appropriate tools if needed.
- Follow the vehicle manufacturer’s torque settings for pedal mounting bolts.
- After fitting, perform an accelerator pedal adaptation or throttle relearn with an appropriate diagnostic tool (DiagBox/Lexia/PP2000 recommended for Stellantis vehicles) to ensure correct mapping and elimination of fault codes.
Why The Part Most Commonly Fails
Failures typically stem from electrical contact wear inside the sensor (potentiometer), moisture ingress, connector corrosion, mechanical wear or impact damage to the pedal assembly. Symptoms include erratic throttle response, check engine light illumination, reduced engine power (limp mode) or no throttle response. Regular inspection of the connector and harness after water ingress or cabin contamination can prevent premature failure.
Search And Compatibility Tips
This part is frequently sought by its product numbers: 0280755164, 9671840280 and 1601CQ. Use these codes when searching parts catalogues or ordering to increase the chance of finding the correct direct-fit unit for Citroën C4, Citroën C4 II, DS4 and Peugeot 308 models.
Additional Notes
Being an electronic component, handle the unit carefully to avoid static or mechanical damage. If you are unsure about performing the replacement or performing the adaptation procedure, seek assistance from a workshop with PSA diagnostic equipment to ensure correct installation and calibration.
