Description
Throttle potentiometer Bosch for Citroën Peugeot vehicles.
High-quality Bosch throttle potentiometer designed for a range of Citroën and Peugeot models. This accelerator pedal position sensor is commonly searched by OE numbers (e.g. 0280752251, 9646702180) and is suitable for professional workshops and DIY mechanics who require reliable measurement of pedal position for correct engine management and driveability. Replacing a faulty potentiometer restores precise throttle response, eliminates hesitation or limp-home mode, and clears related fault codes when the rest of the throttle system is in good condition.
Technical Information
- Manufacturer: Bosch
- Model: Citroën C2; Citroën C3; Citroën C3 Pluriel; Peugeot 1007; Peugeot 307
- Product Codes: 0280752251

Function
The throttle potentiometer (accelerator pedal position sensor) converts the driver’s pedal movement into an electrical signal that the engine control unit (ECU) uses to regulate fuel injection, ignition timing and, in drive-by-wire systems, the throttle valve. Accurate sensor output is essential for smooth acceleration, correct idle control and safe engine management.
Symptoms Of A Faulty Unit
- Intermittent or poor throttle response; hesitation under acceleration.
- Engine Warning Light (MIL) or Stored Fault Codes Related To Pedal Position.
- Limp-home mode or reduced engine power.
- Unstable idle or surging when releasing the throttle.
Most Common Failure Reasons
- Wear Of Internal Resistive Tracks Or Sensors Caused By Prolonged Use.
- Contamination From Dirt, Moisture Or Road Salt Leading To Corrosion Or Short Circuits.
- Connector Damage Or Broken Wiring Due To Mechanical Stress Or Poor Contact.
- Impact Or Mechanical Damage To Pedal Assembly During Repairs.
Installation Recommendations
For safe and reliable replacement follow these steps:
- Disconnect The Negative Battery Terminal Before Starting Work To Avoid Electrical Faults.
- Remove Any Interior Trim Panels Required To Access The Accelerator Pedal Assembly.
- Unplug The Electrical Connector And Inspect Pins For Corrosion Or Damage.
- Unscrew The Mounting Fasteners, Replace The Potentiometer, And Refit Using The Original Fixings.
- After Installation Reconnect Battery And Clear Any Stored Fault Codes; Carry Out Throttle/Accelerator Adaptation If Required Using A Diagnostic Tool.
- Check For Proper Pedal Travel, Smooth Signal Behavior And That No Additional Faults Persist In The Throttle System.
Notes For Mechanics And DIYers
This Bosch unit matches popular OE numbers and is a direct-fit solution for the listed models. There Is No Fixed Replacement Interval—failure is influenced by driving conditions, exposure to moisture and mechanical handling. When replacing, always verify connector integrity and ensure the ECU adaptation procedure is completed where applicable to restore correct throttle mapping.
Buying by OE number is common for quick identification: include 0280752251, 9646702180 or 1601K7 when searching to find the correct part for Citroën and Peugeot applications.
