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.
