Applications
Compatible with a range of Stellantis small- and compact-car platforms. Confirm fitment by matching the vehicle model and the part numbers listed above. Typical applications include early 2000s Citroën C2 / C3 family and Peugeot 1007 / 307 models that use an electronic accelerator pedal sensor.
Function And Common Symptoms
The throttle pedal assembly measures pedal position and transmits an electrical signal to the engine control unit (ECU). In vehicles with electronic throttle control (drive-by-wire), this sensor is critical for accurate throttle response, cruise control operation and safety systems. When the pedal or its sensor fails, common symptoms include uneven idle, reduced engine power or limp-home mode, throttle hesitation, illuminated engine or throttle warning lights, and unresponsive accelerator input.
Replacement Procedure
General replacement steps (procedures can vary by model; always refer to the vehicle service manual):
- Disconnect the negative battery terminal before starting work to prevent electrical damage.
- Remove any trim or footwell covers to access the pedal assembly.
- Unplug the electrical connector from the pedal sensor and inspect the connector for corrosion or damaged pins.
- Unscrew the mounting bolts securing the pedal assembly to the pedal box and remove the old unit.
- Install the new pedal assembly, tighten bolts to the manufacturer’s specified torque, reconnect the electrical connector and reassemble trim.
- Reconnect the battery and carry out any required throttle/ECU adaptation or relearn procedure. Some vehicles may perform a self‑learn routine; others may require a diagnostic tool to complete adaptation.
Installation Recommendations
- Always disconnect the battery before removing or installing the pedal assembly to avoid short circuits and ECU damage.
- Inspect wiring harness and connector for chafing, corrosion or previous repair — faulty wiring is a common cause of new unit failures.
- Ensure connector pins are clean and fully engaged; use dielectric grease sparingly on terminals if exposed to moisture.
- Do not force the pedal into position; align mounting points and tighten fasteners to the correct torque values specified in the service manual.
- After installation, verify correct operation on a test drive and clear any stored fault codes. If throttle adaptation is required, perform it with a compatible diagnostic tool or follow the manufacturer procedure.
Why This Part Fails Most Often
- Electrical Wear: Internal potentiometers or Hall sensors degrade over time, causing inaccurate pedal position signals.
- Contamination And Corrosion: Moisture, dirt or salts entering the connector or housing can cause intermittent faults or permanent failure.
- Mechanical Damage: Impact, excessive pedal force or broken mounting points can impair the assembly.
- Wiring And Connector Issues: Damaged wires, poor crimps or corroded pins lead to signal loss and fault codes.
Buy with confidence when matching the listed product codes to your vehicle. Suitable for professional fitment or experienced DIY replacement; combining a correct installation with proper electrical checks will restore reliable throttle response and safe vehicle operation.
