Description
Bosch Accelerator Pedal For Citroën And Peugeot Vehicles
This Bosch electronic accelerator pedal (throttle pedal assembly) is a direct-fit replacement for many Citroën and Peugeot models. Designed as an OEM-quality Bosch unit, it houses the accelerator position sensor that communicates driver input to the engine management system. The unit improves throttle response accuracy and restores safe, predictable pedal feel on vehicles where the original sensor has degraded or failed. Commonly searched by part numbers 0280755167, 9671416880, 1601EA and 1601AG, this pedal is suitable for both professional workshops and experienced DIY mechanics.

Function And Benefits
The accelerator pedal assembly contains the position sensor (potentiometer or Hall-effect sensor array) that converts pedal travel into an electrical signal for the engine control unit. A correctly functioning pedal ensures precise throttle control, stable idle, reduced hesitation and proper integration with traction and stability systems. Replacing a faulty pedal eliminates erratic acceleration signals and related fault codes.
Replacement Procedure
- Park the vehicle on a level surface, engage the parking brake and chock wheels for safety.
- Disconnect the negative battery terminal before any work on the pedal electrical system.
- Remove lower dash or footwell trim to access the pedal assembly.
- Unplug the electrical connector and release any retaining clips from the wiring harness.
- Unscrew the pedal mounting bolts (typically 2–3 fasteners), remove the old assembly and fit the new pedal in reverse order.
- Reconnect the electrical connector and reassemble trim. Reconnect the battery.
- Perform throttle adaptation/initialization if required by the vehicle—some models require a relearn procedure to restore correct pedal-to-throttle mapping.
Installation Recommendations
- Always disconnect the battery before starting to avoid short circuits and to protect electronic modules.
- Use appropriate tools and follow manufacturer torque specifications for mounting bolts where available.
- Inspect the wiring harness and connector for corrosion or damage; repair any compromised wiring before installing the new pedal.
- After installation, clear any stored diagnostic trouble codes and perform a throttle relearn if the vehicle manufacturer specifies it.
- When available, use factory service information for access steps and initialization routines.
Most Common Causes Of Failure
- Wear Of The Sensor Elements: Over time the internal sensor (potentiometer or Hall sensors) can degrade, producing erratic signals.
- Contamination And Moisture Ingress: Water or dirt entering the pedal housing can cause corrosion and electrical faults.
- Connector Or Wiring Damage: Broken wires, corroded pins or loose connectors lead to intermittent or permanent loss of signal.
- Mechanical Damage: Impact, worn return springs or broken mounting points affect pedal travel and sensor alignment.
- High Mileage Or Harsh Use: Faults are more likely on high-mileage vehicles or those exposed to moisture and aggressive cleaning methods.
Compatibility And Fitment
This accelerator pedal is listed for a range of Citroën and Peugeot models (see Technical Information above). The part is frequently identified and ordered by its OEM and Bosch reference numbers. Before installation, verify that one of the listed product codes matches the number on the original pedal to ensure correct fitment and connector compatibility.
Why Choose This Part
Choosing an OEM Bosch accelerator pedal restores original performance and reliability. For workshops and experienced DIYers, replacing a faulty pedal resolves throttle-related fault codes and unpredictable engine response, returning the vehicle to safe and predictable operation.
Notes
Do not attempt modifications to the sensor or connector. If the vehicle displays persistent driveability issues after replacement, further diagnosis of the throttle body, wiring harness and engine control unit is recommended.
