Description
Throttle Pedal Potentiometer For Citroën C5 2002–2007 And Peugeot 407 With Cruise Control Sensor – Kickdown Tested – All Values OK
This Bosch accelerator pedal assembly (reference 1601Q4) is a direct-fit electronic throttle potentiometer designed for Citroën C5 (2002–2007) and Peugeot 407 models. Ideal for professional garages and DIY mechanics, the unit includes the cruise control/kickdown sensor and is commonly searched by OEM and supplier codes, so listing part numbers when ordering speeds up correct selection. Robust Bosch manufacturing ensures precise pedal position feedback to the engine control unit for smooth throttle response and reliable cruise/kickdown signalling.
Function And Benefits
The pedal potentiometer converts mechanical pedal travel into an electrical signal (accelerator pedal position) for the engine ECU and transmission management. Integrated cruise control/kickdown sensing provides the signal required to disengage cruise or request downshift for maximum acceleration. Benefits include accurate throttle modulation, improved drivability, and compatibility with original wiring and mounting points.
Replacement Guide
- Preparation: Park vehicle on a level surface, engage parking brake and disconnect the negative battery terminal before starting work.
- Access: Remove lower dashboard trim and protective panels around the pedal box to reach the pedal assembly.
- Disconnect: Unplug the electrical connector and release any retaining clips; note connector orientation and locking tab position.
- Remove: Unscrew the mounting bolts securing the pedal assembly to the bulkhead or pedal bracket and remove the old unit.
- Install: Fit the replacement pedal, tighten mounting bolts to manufacturer recommendations, reconnect the electrical plug and reassemble trims.
- Post-Installation: Clear related fault codes with a diagnostic tool and perform any required throttle/pedal adaptation or calibration. Some vehicles may learn pedal parameters automatically after driving, while others may require a diagnostic interface to complete adaptation.
Installation Recommendations
- Always Disconnect The Battery Before Handling Electronic Components To Prevent Damage And Fault Codes.
- Check Connector Pins And Wiring For Corrosion Or Damage Before Fitting The New Pedal.
- Use An Approved Diagnostic Tool To Clear Fault Codes And, If Necessary, Perform Pedal/Throttle Adaptation After Replacement.
- Tighten Mounting Fasteners Securely And Ensure The Pedal Moves Freely Without Obstruction From Mats Or Trim.
Why The Part Most Commonly Fails
Failures Typically Result From Electrical Wear Or Contamination Of The Internal Potentiometer, Corrosion Or Broken Pins In The Connector, Water Ingress, Or Mechanical Damage From Excessive Force Or Impact. Intermittent Signals Or Sticking Pedal Feel Are Common Symptoms. Heat And Long-Term Use Can Accelerate Wear Of Internal Components.
