Technical Information

• Manufacturer: Bosch
• Model: Citroën C5 (2002–2007), Peugeot 407
• Product Codes: 9650341780, 0280755012, F00C3E2429
• Additional Numbers: 1601Q4, 1601Q0, 280755012

Function And Features

The module measures accelerator pedal position via an internal potentiometer array and transmits an analogue/electronic signal to the engine/traction control systems. It also includes the cruise-control/kickdown switch used to disengage cruise and provide a rapid throttle input for automatic transmission kickdown. Because the unit is an electronic sensor, it eliminates mechanical cable wear common on older systems and improves pedal precision.

Replacement Procedure

• Disconnect Battery Before Work. Always isolate the vehicle battery to avoid short circuits and to protect vehicle electronics.
• Access Pedal Assembly. Remove lower dash trim or footwell panels to reach the pedal mounting points and connector.
• Disconnect Electrical Connector. Release the locking tab and carefully unplug the harness—do not pull on wires.
• Remove Fasteners. Unscrew the mounting bolts securing the pedal module to the bracket and remove the old unit.
• Fit New Unit. Position the replacement pedal, tighten bolts to the manufacturer’s recommended torque where available, and reconnect the electrical plug.
• Initial Checks. Reconnect the battery, clear any stored fault codes and verify pedal signal and cruise/kickdown operation with a diagnostic tool. Test drive to confirm correct response.

Installation Recommendations

• Perform Installation In A Dry, Clean Environment To Prevent Contamination Of Connectors.
• Use Proper Tools And Observe Torque Values If Specified By The Vehicle Manufacturer.
• Avoid Excessive Bending Or Strain On The Wiring Harness During Fitment.
• After Installation, Clear Fault Codes And Perform Throttle/Pedal Checks With A Diagnostic Scanner To Verify Signal Integrity.
• If Cruise Control Or Transmission Kickdown Is Affected After Replacement, Recheck Connections And Run A Full System Scan.

Why The Part Fails Most Often

• Electrical Wear And Degradation: Internal potentiometer tracks or sensor electronics can wear over time, causing incorrect or noisy signals.
• Moisture And Corrosion: Water ingress or corroded connectors lead to intermittent faults or total loss of signal.
• Physical Damage: Impact in a collision or excessive force during removal/installation can damage the housing or connector.
• Wiring Problems: Chafed or broken wires in the pedal harness produce unstable readings and fault codes.
• Symptoms Include: Erratic throttle response, delayed acceleration, cruise control failure, and engine limp mode with throttle-related fault codes.

Choose this Bosch throttle potentiometer pedal when you need an OE-referenced replacement that matches the original part numbers for Citroën C5 (2002–2007) and Peugeot 407. Ideal for professional garages and experienced DIYers seeking reliable performance and straightforward installation. Order now to restore precise throttle control and cruise/kickdown functionality.

This Bosch accelerator pedal assembly (throttle potentiometer) is a direct-fit solution for Citroën C5 (2002–2007) and Peugeot 407 models where the electronic throttle and cruise/kickdown sensor are integrated in the pedal unit. Designed to restore precise throttle response and reliable cruise control operation, the unit is commonly sought under OEM and Bosch reference numbers (see technical section). Ideal for professional workshops and experienced DIY mechanics who search by part number when repairing drive-by-wire systems.

As an electronic component that translates pedal travel into a throttle signal, this potentiometer assembly ensures smooth acceleration feedback and accurate kickdown input for automatic transmissions. The pedal communicates with the engine management and cruise systems; symptoms of a failing unit include intermittent throttle response, cruise control faults, fault codes stored in the ECU, or limp-home behavior.

Technical Information

• Manufacturer: Bosch
• Model: Citroën C5 (2002–2007); Peugeot 407
• Product Codes: 0280755012; F00C3E2429; 1601Q4; 1601Q0
• Other Numbers: 9650341780; 280755012

Installation Recommendations

• Safety First: Always disconnect the battery before starting work to avoid electrical damage and accidental throttle activation.
• Removal: Remove lower dash or footwell trim as required to access the pedal. Unplug the electrical connector and remove the retaining bolts holding the pedal assembly to the pedal carrier or bracket.
• Fitment: Fit the replacement pedal in the same orientation, secure bolts to the manufacturer’s recommended torque, and ensure the electrical connector is fully engaged and locked.
• Post-Installation: Clear any stored fault codes and perform a functional check of throttle response and cruise control. Some vehicles may require an adaptation or basic throttle relearn with diagnostic equipment to restore optimal response.
• Tooling: A basic set of hand tools is sufficient for mechanical swap; for fault-code clearing and adaptation, use appropriate diagnostic tools available at garages.

Why This Part Commonly Fails

• Wear Of Internal Potentiometer Contacts: Repeated pedal movement over years causes contact wear or drift, producing inaccurate position signals.
• Contamination And Moisture: Dirt, water ingress or corrosion in the connector or housing can lead to intermittent signals or complete failure.
• Mechanical Stress: Excessive force, impact, or misaligned installation can damage the sensor housing or linkage.
• Wiring And Connector Issues: Chafed wires or poor connector contacts can mimic a faulty pedal sensor.

Notes: Always follow the vehicle manufacturer’s repair manual for removal and installation procedures. After fitting, verify operation under real driving conditions—check smooth throttle response, absence of error codes, and proper cruise/kickdown function.
