Description
HELLA Throttle Pedal for Citroën and Peugeot Vehicles
High-quality HELLA accelerator (throttle) pedal assembly designed for select Citroën and Peugeot models. This electronic pedal integrates the position sensing element used by the engine management system to control throttle response and idle stability. Ideal for professional workshops and experienced DIYers looking for a direct-fit replacement by part number 9671433880 / 1601CX. Clear OE references and robust construction make this unit suitable for routine repairs or powertrain diagnostics where throttle signal faults are present.

Application
Direct fit for various Stellantis models including (but not necessarily limited to): Citroën C-Elysée, Citroën C3 III, Peugeot 207, Peugeot 301, Peugeot 308. Often searched and identified by OE number 9671433880 or internal code 1601CX.
Function And Technical Notes
The accelerator pedal assembly contains a position sensor (typically a potentiometer or Hall-effect sensor) that converts pedal travel into an electrical signal for the engine control unit. Accurate pedal position data is essential for throttle-by-wire systems to ensure correct engine response, cruise control operation and fault-free idling. This unit is a plug-and-play mechanical assembly when matched to the correct connector and vehicle wiring harness; electrical coding or adaptation may be necessary in some vehicles depending on configuration.
How To Replace
Replacement is straightforward for a trained technician. General steps:
- Disconnect Battery Before Work: Always isolate the vehicle battery to avoid accidental short circuits and to protect electronic systems.
- Access Pedal Module: Remove lower dash trim or driver footwell covers to reach the pedal assembly.
- Unplug Electrical Connector: Release the locking tab and carefully unplug the connector to avoid damage to pins.
- Remove Mounting Bolts: Unscrew the retaining bolts and remove the old pedal assembly.
- Install New Unit: Fit the new pedal, torque bolts to manufacturer specifications, and reconnect the electrical connector.
- Re-connect Battery And Check: Reconnect battery and perform basic checks for throttle signal and any ECU fault codes. Clear errors if present and verify pedal response by performing an ignition cycle and observing idle/throttle behavior.
Installation Recommendations
- Use Proper Tools: Remove and install the pedal with appropriate hand tools to avoid damaging mounting points or the sensor housing.
- Observe ESD And Handling Care: Avoid contact with electronic contacts and do not expose the sensor to liquids or contaminants during installation.
- Follow Manufacturer Torque Specs: Fasteners should be tightened to the vehicle manufacturer’s recommended torque to ensure secure mounting.
- Post-Installation Checks: Verify there are no throttle-related fault codes and confirm smooth pedal travel without binding. If faults persist, inspect wiring harness and connector continuity.
Why This Part Most Commonly Fails
Failures are usually caused by electrical wear or mechanical issues rather than scheduled wear-out. Common causes include:
- Sensor Drift Or Internal Wear: Over time the sensing element (potentiometer or hall sensor) can lose accuracy, causing inconsistent throttle signals.
- Contamination Or Moisture Ingress: Dirt, moisture or corrosion on connectors or inside the housing can lead to intermittent faults.
- Damaged Wiring Or Connector: Chafed wiring, broken pins or poorly seated connectors produce signal loss or false readings.
- Mechanical Damage: Impact, excessive pedal force or broken return springs can impair pedal travel and sensor alignment.
Service Life And Diagnostics
There is no fixed replacement interval for accelerator pedals; many last the vehicle’s lifetime. Replacement is recommended when diagnostic trouble codes indicate pedal sensor faults, when there is erratic throttle response, or when the pedal shows mechanical binding. Use a diagnostic scanner to read throttle position values and compare against expected ranges during pedal travel.
Why Choose This Unit
Purchasing a genuine HELLA-coded accelerator pedal by the OE references ensures a direct-fit, correctly specified sensor for the listed Citroën and Peugeot applications. Using the correct part number speeds up repair, reduces diagnostic time and restores reliable throttle control.
