Description
Accelerator Pedal Potentiometer BOSCH for Citroën Berlingo, C4 and Peugeot Partner, 307
Product Overview
This Bosch accelerator pedal potentiometer is a direct-fit electronic throttle position sensor designed for a range of PSA Group vehicles. The unit measures pedal travel and converts it into an electrical signal for the engine control unit, ensuring precise throttle response and drive-by-wire operation. Suitable for professional workshops and experienced DIY mechanics, this part is commonly searched by its OEM codes and is ideal when replacing a worn or faulty pedal sensor to restore smooth acceleration and eliminate throttle-related fault codes.

Applications
Designed for use on a range of Citroën and Peugeot models from the PSA platform. Always verify fitment by checking the part number against the vehicle’s existing unit. Typical applications include Berlingo, C4, Partner and 307 models that use an electronic accelerator pedal potentiometer.
Symptoms Indicating Replacement
- Erratic throttle response or hesitation during acceleration
- Intermittent loss of power or engine entering limp-home mode
- Throttle-related fault codes stored in ECU (e.g. TPS circuit faults)
- Unstable idle or delayed engine response to pedal input
Installation Recommendations
For a safe and effective replacement follow these guidelines:
- Work In A Secure Environment: Park on a level surface, engage handbrake and remove ignition key.
- Disconnect Battery: For safety and to protect vehicle electronics, disconnect the negative battery terminal before starting electrical work.
- Access Pedal Assembly: Remove lower trim panels or footwell covers to reach the pedal unit.
- Unplug Connector: Carefully release the electrical connector latch before pulling it free. Inspect connector pins for corrosion or damage.
- Remove Fasteners: Unscrew the mounting bolts securing the pedal sensor to the pedal assembly or bulkhead and remove the old unit.
- Fit New Unit: Position the replacement pedal potentiometer, tighten fasteners evenly, and reconnect the electrical plug until it clicks.
- Calibration/Adaptation: Many PSA models require a throttle/pedal adaptation or relearn procedure via diagnostic equipment to ensure correct idle and throttle mapping. If unsure, perform an adaptation with appropriate diagnostic tools.
- Final Check: Reconnect the battery, clear any stored fault codes, and test drive to confirm correct throttle response and absence of warning lights.
Why This Part Fails Most Often
Failure of accelerator pedal potentiometers is typically caused by internal wear of the potentiometer element, contamination from moisture or debris, and connector corrosion. Frequent heavy use, ingress of dirt in older vehicles, or electrical spikes can accelerate wear. Mechanical damage to the pedal assembly or wiring harness faults also cause malfunction and erratic signals to the ECU.
Expected Service Life
There Is No Fixed Replacement Interval. Under normal conditions the unit should last many years, but failures commonly appear after high mileage or in vehicles exposed to moisture and contaminants. Replace the unit at the first sign of erratic behavior to avoid drivability issues.
Recommended Tools And Tips
- Basic Hand Tools: Socket set, Torx or hex keys as required by vehicle fasteners
- Multimeter: For quick checks of signal and supply voltage at the connector
- Diagnostic Tool: Recommended to clear faults and perform pedal/throttle adaptation
- Handling Tip: Avoid bending or tugging wiring, ensure connector locks fully, and do not force mounting bolts past their original torque.
