Description
Accelerator pedal for Citroën, Peugeot and DS vehicles. It is from Citroën C4 II.
This Bosch accelerator pedal module (part numbers 0280755164, 9671840280, 1601CQ) is a direct-fit electronic throttle position sensor used on a range of Stellantis models. Designed for modern drive-by-wire systems, the unit converts pedal travel into an electrical signal for the engine control unit (ECU). The assembly is a common replacement item for workshops and DIY mechanics searching by OE number or model fitment. Installing a genuine Bosch pedal restores precise throttle response and eliminates accelerator-related fault codes that affect drivability.
Technical Information
- Manufacturer: Bosch
- Model: Citroën C4 II; Compatible With DS4, Peugeot 308
- Product Codes: 0280755164, 9671840280, 1601CQ
- Other Numbers: OE/PSA References Often Used By Dealers And Garages
Function And Application
The pedal module houses a position sensor (potentiometer or Hall-effect sensor) that measures the driver’s throttle input and transmits a proportional signal to the ECU. The ECU then controls the throttle body or engine management to match the demanded torque. Correct operation is essential for smooth acceleration, cruise control function and emission control. This unit is typically fitted on passenger cars with electronic throttle control rather than a mechanical cable.
Installation Recommendations
- Disconnect the negative battery terminal before starting work to prevent electrical faults.
- Access the pedal from the driver’s footwell: remove any lower dash or trim panels as required to reach the mounting bolts and electrical connector.
- Unplug the electrical connector and remove the pedal assembly mounting bolts. Keep the mounting area clean and check the wiring harness for damage or corrosion.
- Fit the new pedal in the original position and secure the fasteners to the manufacturer’s specification where available. Reconnect the electrical connector and reassemble trim.
- After replacement, clear stored fault codes and perform a throttle adaptation or relearn procedure with a diagnostic tool if required by the vehicle. Verify idle and throttle response during a test drive.
Common Failure Causes
Accelerator pedal modules typically fail due to sensor wear, contamination, or electrical connector problems. Frequent causes include:
- Wear of internal sensor elements (potentiometer wear or Hall sensor drift) leading to inconsistent signal output.
- Moisture ingress or dirt contamination causing intermittent faults or corrosion of contacts.
- Damaged wiring or connector corrosion from mechanical stress or exposure.
- Physical damage to the pedal arm or return spring from heavy use or accidents.
Compatibility & Notes
This part is commonly searched by OE numbers 0280755164, 9671840280 and 1601CQ. It is known to fit Citroën C4 II and is compatible with related Stellantis models such as DS4 and Peugeot 308 where the same pedal module is specified. Always confirm visual match of connector and mounting points during fitment.
Suitable for professional workshops and independent mechanics looking for reliable replacement parts with clear OE identification. Replace a faulty pedal to restore accurate throttle control and improve drivability.
