Description
Product Overview
This throttle body is designed for the 2.0 HDI diesel engine, commonly found in Peugeot and Citroën vehicles. It regulates the air intake flow to the engine, directly influencing combustion efficiency and engine response. The throttle body part number 9657522480 (alternative codes 0345F0, 0345E9) suits models equipped with the RHR 100 kW engine.
Function and Importance
The throttle body controls the amount of air entering the intake manifold, working in conjunction with the engine control unit (ECU) to optimize fuel injection and maintain ideal air-fuel mixture. A properly functioning throttle body ensures smooth acceleration, engine idling stability, and overall vehicle performance.
Common Issues and Replacement
Over time, throttle bodies may accumulate carbon deposits or suffer electronic sensor faults causing poor idle, engine hesitation, or reduced power delivery. Regular inspection is recommended, especially if engine warning lights are present or performance issues arise. Replacement involves disconnecting the air intake hose, unplugging electrical connectors, and unbolting the throttle body from the intake manifold.
