Product Overview

This Bosch throttle potentiometer (accelerator pedal module) is a direct-fit electronic pedal assembly designed for Citroën and Peugeot models. Built to OEM standards, it restores precise pedal position sensing in drive-by-wire systems, improving throttle response, drivability and eliminating erratic acceleration or limp-home modes caused by a faulty pedal potentiometer. Commonly searched by part numbers, this unit matches the reference codes used across Stellantis applications.

Function And Benefits

The pedal potentiometer converts mechanical pedal movement into an electrical signal that the engine control unit uses to control engine torque and throttle response. In modern Citroën/Peugeot cars this component is critical for smooth acceleration, cruise control behavior and safety interventions. Replacing a worn or faulty pedal module returns accurate pedal mapping, reduces hesitation, and clears pedal-related fault codes.

Replacement Procedure (Overview)

Replacing the accelerator pedal potentiometer is a straightforward task for a trained technician or an experienced DIYer with basic tools. Typical steps:

• Disconnect the vehicle battery before beginning work to avoid electrical damage and for safety.
• Remove interior trim panels around the pedal box to access the pedal assembly.
• Unplug the electrical connector and remove the retaining bolts securing the pedal module.
• Install the new pedal module, tighten bolts to manufacturer torque, and reconnect the electrical connector.
• Reconnect the battery and perform pedal/idle adaptation if required by the vehicle (some models may need a throttle or pedal calibration procedure via diagnostic tool).

Installation Recommendations

• Always disconnect the battery before removal and follow the vehicle manufacturer’s safety procedures.
• Inspect wiring harnesses and connector pins for corrosion or damage; replace or repair any compromised wiring before fitting the new unit.
• Use appropriate torque settings for pedal mounting bolts to avoid damage; if uncertain, consult a repair manual for the specific model.
• After installation, clear related fault codes and confirm pedal signal values with a diagnostic tool. If the vehicle requires adaptation, perform it with a compatible diagnostic interface to ensure correct response.

Most Common Causes Of Failure

Pedal potentiometers typically fail due to internal wear of the sensor tracks, contamination from dust or moisture, connector corrosion, or mechanical stress at the pedal pivot. Symptoms include irregular throttle response, delayed acceleration, sudden loss of power or persistent pedal-related fault warnings on the instrument cluster.

Compatibility

Fits various Stellantis platforms used on Citroën C2, C3 and C3 Pluriel as well as Peugeot 307. Always verify the part number against the existing component on the vehicle before ordering.

Function

The unit contains position sensors (usually hall-effect or potentiometric sensors) that convert driver pedal movement into an electrical signal sent to the engine control unit (ECU). In modern vehicles this signal controls throttle opening, cruise control and can interact with traction control and stability systems. A precise and responsive pedal ensures correct engine behavior and safe drivability.

Common Faults And Typical Lifetime

Electronic throttle pedals generally last many years, but failures can occur due to wear of internal sensors, contamination (dirt, moisture), connector corrosion or damage to the wiring harness. Symptoms of a failing pedal include erratic throttle response, reduced engine power, throttle warning lights or limp-home mode. Lifetime depends on usage and environment; high mileage and exposure to moisture accelerate sensor degradation.

Installation Recommendation

• Disconnect the battery before starting work and follow the vehicle manufacturer’s safety procedures to avoid damage to electrical systems and stored fault memory.
• Locate and remove the retaining bolts securing the pedal assembly, unplug the electrical connector, and replace with the new unit. Ensure connector pins are clean and fully engaged.
• After fitting, some vehicles may require throttle relearn or calibration via a diagnostic tool for correct idle and response. If you are unsure, perform a basic throttle check and read fault codes with an OBD-II scanner.
• Torque fasteners to manufacturer specification and check for correct pedal travel and smooth operation before road testing.

Why The Part Fails Most Often

Failures are most often caused by internal sensor wear, contamination from water or road grime, and connector or wiring corrosion. Mechanical impacts or improper handling during previous repairs can also damage the unit. Regular inspection of the pedal area and wiring can prevent unexpected faults.

Who Should Fit This Part

Suitable for professional mechanics and experienced DIYers comfortable with electrical connectors and basic calibration procedures. For vehicles that require advanced coding or adaptation after replacement, use professional diagnostic equipment or seek a qualified workshop.
