Fitment And Application Notes
This throttle body housing is intended for petrol VTI engines listed above. It is commonly used as a direct replacement when the original throttle body exhibits sticking, poor idle control or electronic fault codes related to throttle position. Always verify engine type (1.4 16V VTI / 1.6 16V VTI) and part number before ordering to ensure correct fitment.
How To Replace
- Prepare: Park vehicle on level ground, engage handbrake and disconnect the negative battery terminal to avoid electrical faults.
- Access: Remove the intake hose and airbox parts obstructing access to the throttle body. Take care not to damage vacuum lines or sensors.
- Disconnect: Unplug the electrical connector(s) and any vacuum hoses attached to the throttle body.
- Remove: Unscrew the mounting bolts and gently separate the throttle body from the intake manifold. Inspect and remove the old gasket or seal.
- Fitment: Clean the mating surfaces, fit a new gasket (recommended), position the new throttle body and tighten bolts evenly to the manufacturer’s specification.
- Reconnect: Reattach electrical connectors, hoses and intake plumbing. Reconnect the battery.
- Finalise: Perform throttle adaptation/idle relearn according to the vehicle manufacturer’s procedure or using a compatible diagnostic tool if required.
Installation Recommendations
- Disconnect the battery before starting work to protect electronics.
- Replace the throttle body gasket or O‑ring when installing the new unit to prevent vacuum leaks.
- Do not force connectors or hoses; inspect harness condition and pins for corrosion.
- Perform throttle adaptation/idle relearn per manufacturer’s instructions after installation; a diagnostic tool may be required for full calibration.
- Use proper hand tools and avoid overtightening fasteners—follow the vehicle service manual for torque values.
Common Failure Reasons
Throttle bodies on small PSA petrol engines typically fail or cause drivability issues for several reasons:
- Carbon and soot build‑up on the throttle plate and bore, causing sticking and rough idle.
- Wear or failure of the internal potentiometer/position sensor or electronic actuator in electronically controlled units, leading to throttle position faults.
- Vacuum or intake leaks at the throttle housing gasket or associated hoses, creating unstable idle and poor response.
- Contaminated intake air or poor maintenance of the air filtration system accelerating deposit formation.
Expected Service Life
With correct maintenance (clean air filter, periodic intake inspection), throttle bodies typically last well beyond 100,000 km. Failure frequency increases when intake contamination is present or when electrical components degrade with age. Regular inspection during scheduled servicing can prolong component life.
Who Should Fit This Part
Suitable for professional mechanics and competent DIYers with experience on petrol engines. If in doubt about adaptation procedures or electrical diagnostics, consult a workshop with appropriate diagnostic equipment.
