Compatibility
Fits petrol engines: 1.8i, 1.8 16V, 2.0i, 2.0 16V. Check engine model and connector type before installation to ensure correct fitment. Often searched by OE code 9652682880 or 1635W8.
Installation Recommendations
- Disconnect Battery Before Work: Always isolate the battery before removing the throttle body to avoid electrical damage and erroneous ECU inputs.
- Procedure Overview: Remove air intake ducting, unplug the electrical connector, unbolt the throttle body from the inlet manifold, remove old gasket and fit the new unit with a correct gasket surface. Reconnect connector and intake hose.
- Clean Mating Surfaces: Ensure intake manifold mating face is clean and free of carbon and gasket residue to prevent air leaks.
- Post-Installation: Perform throttle adaptation/relearn using a diagnostic tool or follow manufacturer idle adaptation steps to restore correct idle and throttle mapping.
- Use Proper Tools: Avoid damaging sensor pins and the throttle actuator. Torque bolts evenly to manufacturer recommendations.
Why This Part Fails Most Often
- Carbon Build-Up: Accumulation on the throttle plate and bore causes sticking, erratic idle and poor throttle response.
- Wear Of Internal Components: Stepper motor or potentiometer deterioration leads to incorrect position feedback and faults.
- Vacuum Or Air Leaks: Failing gasket or intake leaks around the throttle body produce unstable idle and drivability issues.
- Electrical Problems: Corroded connectors, broken wires or poor contacts cause intermittent faults or loss of signal.
- Age And Mileage: Symptoms are more common on higher-mileage vehicles or where intake maintenance has been neglected.
Practical Tips For Fitters
– Inspect And Replace Gasket: Always fit a new gasket when replacing the throttle body to ensure a sealed connection.
– Check Air Intake System: Verify the air filter and intake hoses for leaks or damage that could affect performance.
– Diagnostic Check: After installation, clear stored fault codes and confirm correct operation under load and idle. If problems persist, inspect wiring and throttle actuator function.
Notes For Buyers
This unit is a direct-replacement option for the listed Citroën and Peugeot applications and is commonly referenced by OE codes 9652682880 and 1635W8. Suitable for both workshop fitment and competent DIY installation when basic diagnostic and adaptation tools are available.
