Description
Throttle body housing for 1.4 16V VTI and 1.6 16V VTI engines for Citroën and Peugeot vehicles.
This Siemens VDO electronic throttle body assembly (drive-by-wire) is designed for Stellantis 1.4 16V VTI and 1.6 16V VTI petrol engines used in a range of Citroën and Peugeot models. Commonly searched under part numbers V760491980, V760491980-01, A2C53386323 or 163673, the unit controls the amount of intake air entering the engine and contains the throttle plate and position sensing/electronic actuator components. For professional mechanics and DIY enthusiasts, this replacement part restores precise throttle response, idle stability and drivability when the original throttle body shows wear or electronic faults.
Compatibility
Fits engines: 1.4 16V VTI, 1.6 16V VTI.
Typical compatible models (examples): Citroën Berlingo B9; Citroën C3; Citroën C3 II; Citroën C3 Picasso; Citroën C4 II; DS3; Peugeot 207; Peugeot 308; Peugeot Partner Tepee. Always check part numbers against the vehicle’s requirements.
Key Benefits
- Direct OE-style replacement by Siemens VDO design.
- Restores smooth idle, throttle response and fuel efficiency.
- Reduces hesitation, stalling and limp-home mode related to throttle faults.
- Includes common OEM reference numbers for easier matching (see Technical Information).
How It Works And Symptoms Of Failure
The throttle body regulates airflow to the engine via a throttle plate controlled by an electronic motor and monitored by a throttle position sensor. Symptoms of a failing throttle body include irregular or high idle, poor throttle response, engine hesitation, stalling at low revs and persistent check engine lamp codes related to throttle position or airflow. Carbon buildup around the throttle plate and electrical faults in the actuator or sensor are the most frequent causes.
Replacement Procedure (Overview)
- Prepare: Work on a cool engine, park on level ground and use appropriate hand and safety tools.
- Disconnect intake ducting and airbox to access the throttle body. Unplug electrical connectors and any vacuum hoses or sensors attached.
- Unbolt the throttle body from the intake manifold and remove the old gasket. Fit the new unit with a new gasket if supplied.
- Reconnect electrical connectors, hoses and intake ducting. Reattach battery if disconnected and follow relearn/adaptation procedure as required.
- Start engine and check for smooth idle and absence of fault codes. Perform throttle adaptation using a diagnostic tool if necessary.
Installation Recommendation
Always follow the vehicle manufacturer’s service manual. Replace the throttle body gasket and clean surrounding mating surfaces before installation. After fitting, perform throttle adaptation or idle relearn as specified for the vehicle—many drive-by-wire systems require an electronic relearn via a diagnostic tool or a specific ignition/idle procedure. Torque fasteners to manufacturer specifications.
Most Common Reasons For Failure
- Carbon and oil deposits accumulating on the throttle plate causing sticking or incorrect air metering.
- Wear or failure of the electronic actuator or throttle position sensor leading to incorrect position feedback.
- Corroded or damaged electrical connectors and wiring causing intermittent faults.
- Vacuum leaks or intake leaks affecting airflow and idle control.
