Fitment And Applications

Primarily intended for Peugeot 307 CC (Coupe Cabriolet) models equipped with electronic throttle control. Always verify physical match of mounting points and electrical connector before installation. This item is commonly sought using the listed part numbers.

Function

The pedal assembly measures the driver’s accelerator input and sends an electronic signal to the engine control unit (ECU) or throttle body. Proper function is essential for smooth throttle response, accurate idle control and drivability. A faulty pedal can cause hesitation, limp-home mode or throttle-related fault codes.

Replacement Procedure

1. Disconnect the negative battery terminal before starting work to avoid electrical damage.
2. Remove lower dash or footwell trim to access the accelerator pedal assembly.
3. Unplug the multi-pin electrical connector and inspect for corrosion or damaged pins.
4. Unscrew the pedal mounting bolts and remove the old assembly.
5. Install the new pedal, tighten bolts to manufacturer recommendations, and reconnect the electrical connector.
6. Reconnect the battery, check for fault codes and clear them with a diagnostic tool if present. Cycle ignition and perform a basic throttle check; some vehicles may require ECU adaptation or throttle relearn using diagnostic equipment.

Installation Recommendations

• Always disconnect the battery prior to removal/installation and follow vehicle manufacturer procedures to prevent damage to electronic components.
• Inspect wiring harness and connector for wear or corrosion and repair any damaged wiring before fitting the new pedal.
• Use appropriate hand tools and torque settings; avoid over-tightening mounting fasteners.
• After installation, clear fault codes and verify throttle response on the road or on a diagnostic tester.
• Estimated replacement time: 30–60 minutes depending on trim removal and workshop experience.

Why It Fails Most Often

Common causes of pedal assembly failure include wear of the internal position sensor, contamination or moisture ingress into the connector, connector corrosion, and physical damage from impact or excessive force. Wiring faults and connector problems are frequent contributors to intermittent signals or failure.
