Description
Product Overview
This intake throttle valve (throttle body) is intended for PSA 1.6 HDi diesel engines. Commonly referenced by part numbers 9649832580 and 0345C1 and supplied in a Delphi style configuration, it is designed as a direct-fit replacement for a range of Citroën and Peugeot models. The component controls air metering into the intake tract and works with the engine management system to stabilise idle and manage EGR-related airflow on diesel applications.
Function And Common Failure Modes
The throttle valve modulates intake air and provides position feedback to the ECU. Typical causes of malfunction include carbon buildup around the valve and shaft, electrical faults in the actuator or position sensor, and wear of moving parts. Symptoms of a failing unit are rough or fluctuating idle, stalling at low speed, reduced throttle response, increased fuel consumption and diagnostic trouble codes stored in the engine control module.
Replacement Guide
Service should be carried out by a qualified technician or an experienced DIY mechanic following vehicle-specific procedures. Typical replacement steps:
- Disconnect the negative battery terminal to avoid electrical damage.
- Locate the throttle body on the intake manifold and remove the air intake ducting and any obstructing components.
- Unplug the electrical connector and remove any vacuum lines or hoses carefully.
- Unscrew the mounting bolts, remove the old unit and replace the gasket if applicable.
- Install the new throttle valve, reconnect wiring and hoses, reattach the intake duct and reconnect the battery.
- Clear fault codes and perform any ECU adaptation or throttle relearn procedure required by the vehicle manufacturer.
