Original HELLA gas pedal – accelerator position sensor for Citroën/Peugeot cars. This is a used, fully functional part dismantled from a PSA car. Suitable as a direct replacement for a faulty pedal/pickup for the models listed below. With accurate signal and redundant sensing, it restores smooth throttle response and eliminates emergency mode caused by APP (Accelerator Pedal Position) error.

Key benefits
– HELLA/PSA original – exact compatibility and reliability
– Direct plug & play replacement without modification
– Redundant (double) sensor for safe operation
– Addresses RPM fluctuations, worse throttle response, safe mode and APP errors

OEM and catalog numbers
– PSA: 1601.Z7 (1601Z7)
– PSA: 9681844480
– Manufacturer: HELLA
Note: The number on your original part must match or be fully interchangeable.

Compatibility (selected models)
– Citroën: C-Elysée, C3 III
– Peugeot: 207, 301, 308
As part of PSA, the pedal was installed in several engines and years. Before purchasing, verify by VIN and part number, or by body shape and connector.

Technical information
– Construction: electronic pedal with double (redundant) position sensor
– Signal to ECU: 2 independent analog channels (A/B) with different characteristics
– Power supply: reference 5 V from engine control unit (common for PSA)
– Connector: multi-pin PSA (typically 6pin; check on the car)
– Mounting: bolted pedal module, located next to the pedal wall in the driver’s compartment
– Communication with the ECU: no need for coding; the control unit adapts the values automatically after switching on the ignition
The specified parameters correspond to the standard design of this part at PSA/HELLA.

Typical fault symptoms that this part addresses
– Delayed or irregular throttle response
– Activation of emergency mode (reduced power)
– OBD fault codes: e.g. P0120-P0124, P0220, P2138 (APP signal mismatch)
– Unstable idling when pressing/releasing the pedal

Installation recommendations
– Before replacing, disconnect the battery and check the wiring and the connector (oxidation, loose pins)
– Replace the entire pedal module as a set
– After assembly, turn on the ignition for approx. 30 s without starting, then start – the ECU usually automatically reads the pedal
– Do not confuse with pedals with a different connector or a different position of the stops

Condition and origin
– Used original HELLA/PSA part
– Normal service wear, fully functional
– Compare the part numbers and visuals to your original pedal

This HELLA accelerator (throttle) pedal is a direct-fit electronic pedal assembly designed for a range of Citroën and Peugeot models. Built to OEM specifications, it replaces worn or faulty pedal position sensors and restores precise drive-by-wire response. Ideal for professional workshops and experienced DIY mechanics, the unit helps eliminate hesitation, limp-home mode and related driveability issues caused by faulty pedal position signals.

Technical Information

• Manufacturer: HELLA
• Model: Fits Citroën C-Elysée, Citroën C3 II, Citroën C3 III, DS3, Peugeot 207, Peugeot 301, Peugeot 308
• Product Codes: 9671433780, 1601CW, 1601Z7
• Other Numbers: 1601.CW, 1601.Z7, 1601z7, 1601.CW; Common Fault Codes: P0120–P0123, P2122–P2127, P2138

Function And Features

The accelerator pedal assembly contains position sensors (potentiometer/hall sensors depending on version) that measure pedal travel and send an electrical signal to the engine control unit (ECU). The ECU uses this input for throttle control, cruise functions and safety interlocks. Benefits of a correctly functioning pedal include smooth throttle response, predictable acceleration and reliable interaction with traction- and stability-control systems.

Symptoms Of A Faulty Pedal

• Check Engine Light with codes such as P0120–P0123, P2122–P2127 or P2138
• Intermittent or delayed throttle response and hesitation under acceleration
• Engine entering limp-home/reduced power mode
• Unstable idle or unexpected engine behavior during throttle input
• Diagnostic scanner shows inconsistent or implausible pedal position readings

Why Pedals Fail

• Wear of internal sensor elements or potentiometer tracks over time
• Contamination from moisture, dirt or corrosion at the connector or inside the assembly
• Mechanical damage from impact or improper handling during removal/installation
• Wiring harness damage, connector corrosion or poor electrical contact

Replacement Interval

There is no fixed service interval for accelerator pedals; they are typically replaced when faulty. Failures are more likely on high-mileage cars or after water ingress or physical damage. Inspect the pedal and wiring if the vehicle shows related fault codes or driveability symptoms.

Installation Recommendations

• Always disconnect the battery before starting work to avoid electrical damage and follow the vehicle manufacturer’s removal/installation procedure.
• Handle the electrical connector carefully; check pins and connector housing for corrosion or deformation.
• Secure the pedal to the mounting points with correct fasteners and torque as specified by the manufacturer.
• After fitting, clear diagnostic trouble codes and perform any required throttle/pedal adaptation or ECU relearn procedure if the vehicle requests it.
• Inspect related wiring and connectors while the pedal is accessible to prevent repeat failures.

Why Choose This Part

This HELLA pedal assembly carries OEM-referenced numbers (9671433780 / 1601CW / 1601Z7) and is a reliable replacement option for Citroën and Peugeot models listed above. It helps restore correct pedal signalling and vehicle drivability—critical for professional repairs and confident DIY maintenance.
