Description
Overview
The Throttle Potentiometer is a precision electronic sensor used on PSA (Citroën and Peugeot) vehicles to monitor throttle position on 1.6, 2.0 and 2.2 HDi engines. Supplied under OE reference numbers 963977180, 1920X1, 1920AK, it is a common replacement part sought under product codes.
Key Benefits
Accurate throttle position feedback for stable idle and responsive acceleration. Designed for professional fitment by mechanics and suitable for experienced DIYers. Retains compatibility with original electrical connectors and mounting points to simplify installation.
Compatibility And Typical Applications
Commonly fitted to PSA diesel models equipped with 1.6 / 2.0 / 2.2 HDi engines, including many Citroën and Peugeot models (e.g. C4, C5, Berlingo, 307, 308). Always cross-reference OE numbers before purchase to ensure exact fitment.
Symptoms And When To Replace
Failing throttle potentiometers typically cause erratic idle, poor throttle response, engine management warning lights or limp-home mode. Failure may result from wear, contamination, water ingress or electrical connector corrosion. Replacement interval depends on use and environment; failures are more common after high mileage or harsh conditions.
Replacement And Installation Notes
Typical replacement steps: disconnect the battery, locate the potentiometer at the throttle body or pedal assembly, unplug the electrical connector, remove retaining screws, install the new unit, reconnect and secure to manufacturer’s torque, then perform throttle/ECU adaptation if required. Keep mating surfaces clean and avoid touching sensor elements. If unsure, have a professional perform final calibration.
