Description
Throttle Potentiometer For Peugeot 307 CC
This replacement throttle potentiometer (accelerator pedal position sensor) is intended for use on Peugeot 307 CC. Ideal for professional workshops and experienced DIYers, the unit restores accurate pedal position feedback to the engine control unit, eliminating erratic throttle response, surging, or limp-home mode caused by a faulty sensor. Searchable by OEM and supplier numbers—useful when customers look up parts by reference.
Technical Information
- Manufacturer: Bosch
- Model: Peugeot 307 CC
- Product Codes: 0280755029
- Additional Numbers: 9647781377, 1601N7, NFP
Fitment
Fits: Peugeot 307 CC (Coupe Cabriolet) models indicated by the listed part numbers. Confirm that the vehicle uses an electronic throttle/pedal position sensor when matching by application.
Function And Typical Symptoms
The pedal potentiometer measures the position of the accelerator pedal and sends an electrical signal to the engine control unit (ECU) in vehicles with drive-by-wire throttle systems. Common symptoms of a failing unit include irregular idle, delayed or jerky throttle response, sudden loss of power, illumination of the engine/ABS warning lights, or the vehicle entering limp-home mode.
Why The Part Commonly Fails
Failures are typically caused by internal wear of the potentiometer contacts, contamination or corrosion of connector pins, water ingress into the pedal module, or wiring/connector damage from heat and vibration. Repeated heavy use and exposure to moisture accelerate degradation of the sensor’s electrical components.
Installation Recommendations
- Disconnect The Battery Before Starting Work To Avoid Electrical Shorts And Unintended Throttle Activation.
- Inspect Wiring And Connector Pins For Corrosion Or Damage; Repair Wiring Looms Before Installing The New Sensor.
- Replace The Sensor According To Vehicle Manufacturer Fastening Points; Tighten Fasteners Securely But Avoid Over-Torquing.
- After Installation, Perform Throttle/Pedal Adaptation Or Calibration Using A Diagnostic Tool Or Follow The Vehicle-Specific Relearning Procedure To Ensure Proper ECU Recognition.
- Apply A Light Coat Of Dielectric Grease To The Connector Pins If Appropriate To Improve Corrosion Resistance.
- Verify Operation With A Test Drive And Check For Stored Fault Codes; Clear Codes After Successful Adaptation.
