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

How To Replace

Replacement is straightforward for experienced technicians: disconnect the battery, remove lower dash or trim panels to access the pedal module, unplug the electrical connector, remove the mounting bolts securing the pedal assembly, fit the replacement unit and torque bolts to manufacturer specification, reconnect the electrical connector and reassemble trim. After installation clear any stored fault codes and perform throttle adaptation/calibration if required by the vehicle.

Mounting Recommendations

• Always disconnect the battery before starting work and follow the vehicle manufacturer’s removal/installation procedure to avoid electrical damage.
• Inspect the wiring harness and connector for corrosion, bent pins or damaged locking tabs before fitting the new pedal.
• Ensure the pedal moves freely without obstruction from trim or carpeting after installation.
• Perform diagnostic checks and throttle adaptation with a suitable scan tool after fitting to restore correct throttle response and clear DTCs.

Reason Why The Part Fails Most Often

• Wear of the internal potentiometer or Hall sensors over time leading to intermittent or incorrect position signals.
• Contamination from moisture, dirt or debris that corrodes contacts or damages sensor electronics.
• Damage to wiring or connector (water ingress, rodent damage, poor previous repairs) causing signal loss or short circuits.
• Mechanical damage from impact or excessive force on the pedal assembly.
• Electronic faults that trigger throttle-related diagnostic trouble codes (e.g., P0120–P0123, P0220) and may place the vehicle in limp mode.

Diagnostic Notes

Common symptoms indicating pedal or sensor faults include throttle hesitation, sudden loss of drive, limp-home mode, inconsistent idle, or illumination of the engine management/warning lamp with codes such as P0120–P0123 and P0220. Use a diagnostic tool to read live pedal position values and compare them to expected ranges while operating the pedal to confirm faults before replacement.

Additional Information

Because this is an electronic pedal assembly, proper electrical connection and calibration are essential for safe operation. Keep part numbers handy when searching or ordering to ensure correct fitment and faster procurement.
