- Check engine light illumination

Diagnosis:
- Inspect ignition components (spark plugs, wires, coils) for wear or damage
- Check fuel injectors and fuel pressure for proper operation
- Perform a compression test to assess cylinder health
- Examine timing belt condition and alignment
- Look for vacuum leaks or intake manifold gasket deterioration
- Scan ECU for stored fault codes related to sensors (oxygen sensor, MAF, TPS)

Fixes:
- Replace worn spark plugs and ignition wires to restore proper firing
- Clean or replace faulty fuel injectors to ensure correct fuel delivery
- Replace timing belt and tensioner if worn or past service interval to prevent engine damage
- Repair or replace leaking gaskets and seals to stop oil leaks
- Address vacuum leaks by replacing cracked hoses or intake gaskets
- Service or replace malfunctioning sensors to improve engine management
- Change engine oil and filter regularly to maintain lubrication and reduce wear

Prevention:
- Follow manufacturer’s recommended maintenance schedule, especially timing belt replacement every 60,000 to 90,000 km
- Use high-quality fuel and oil to reduce deposits and wear
- Regularly inspect ignition system components and replace as needed
- Keep air intake system clean and free of debris
- Monitor engine performance and address issues promptly to avoid escalation
- Avoid prolonged idling and aggressive driving to reduce engine stress

By adhering to these diagnostic steps, fixes, and preventive measures, owners of vehicles equipped with the 3S-GE engine can maintain reliable performance and extend engine life.
