Description
Throttle potentiometer, BOSCH accelerator pedal for Citroën and Peugeot vehicles.
Product Overview
High-quality Bosch throttle potentiometer (accelerator pedal) designed for a range of Citroën and Peugeot models. This electronic accelerator pedal assembly converts driver input into an electrical signal for the engine management system (drive-by-wire). It is a direct-fit replacement for worn or faulty pedals, offering precise throttle response and reliable signal transmission for smooth drivability. Common OEM references include 0280752235 and 9645851580 (also found as 1601K7 NFP in some catalogs).
Technical Information

Compatibility
Fits selected Stellantis Group (Citroën / Peugeot) vehicles listed above. Always verify the part number on the existing unit before installation to ensure exact match and connector type.
Function And Typical Failure Modes
The accelerator pedal assembly contains a potentiometer (or Hall-effect sensors in some designs) that measures pedal position and sends a voltage or digital signal to the engine ECU. Over time the potentiometer elements or electrical contacts can wear, become contaminated, or corrode. Symptoms of a failing pedal include inconsistent throttle response, hesitation, reduced engine power, limp-home mode, or illumination of the engine management warning light.
Installation Recommendations
- Park vehicle on level ground, engage parking brake, and follow safety procedures.
- Before starting work, disconnect the battery to prevent short circuits and protect electronic systems.
- Remove lower dash/footwell trim to access the pedal assembly. Unplug the electrical connector and remove the mounting bolts securing the pedal.
- Install the replacement pedal, tighten mounting bolts to the manufacturer’s torque specification, and ensure the connector is fully seated and locked.
- After installation, reconnect the battery and clear any stored fault codes. On some vehicles a throttle/pedal relearn or adaptation procedure may be required using a diagnostic tool to restore correct idle and throttle mapping.
- Verify pedal travel is free and unobstructed, then perform a road test to confirm normal operation.
Why This Part Most Commonly Fails
- Wear Of Potentiometer Tracks Or Sensors: Repeated use gradually wears sensing elements, producing erratic signals.
- Moisture And Corrosion: Water ingress or corrosion at the connector degrades the electrical contact.
- Contamination: Dirt and dust in the pedal mechanism cause mechanical binding or sensor contamination.
- Electrical Faults: Wiring damage, poor grounding, or intermittent connector faults lead to signal loss.
- Physical Damage: Impact or excessive force can deform the pedal assembly or break mounting points.
Practical Tips For Mechanics And DIYers
- Compare all part numbers and connector pins before fitting to avoid returns and downtime.
- Use a quality diagnostic tool after replacement to check live pedal position values and clear errors.
- If intermittent faults persist, inspect wiring harness and ground points for corrosion or chafing.
- Keep the footwell clean and ensure floor mats do not interfere with pedal travel after fitting.
Warranty And Quality Notes
Bosch components are manufactured to high automotive standards. Replacing a faulty throttle potentiometer restores accurate pedal feedback and helps eliminate drivability issues stemming from incorrect pedal position signals.
