Solution
1. Preparation
  • Gather tools: OBD-II scanner, tire pressure gauge, socket set, oil filter wrench, and basic hand tools.
  • Ensure the vehicle is parked on a level surface and the engine is off.
2. Address Check Engine Light
  • Use the OBD-II scanner to read diagnostic trouble codes (DTCs).
  • If codes indicate issues (e.g., oxygen sensor, mass air flow sensor):
    • Replace faulty sensors based on manufacturer specifications.
3. Check and Adjust Tire Pressure
  • Use a tire pressure gauge to measure the pressure of all tires.
  • Inflate tires to the recommended PSI levels as stated in the owner's manual.
4. Replace Air Filter
  • Locate the air filter housing, typically near the engine.
  • Open the housing and remove the old air filter; clean any debris inside the housing.
  • Install a new air filter per manufacturer specifications.
5. Inspect and Clean Fuel System
  • Check fuel injectors for clogs; use a fuel injector cleaning kit if necessary.
  • Replace the fuel filter if it hasn’t been changed according to the maintenance schedule.
  • Reconnect all fuel lines securely.
6. Change Engine Oil
  • Drain old engine oil using an oil filter wrench to remove the oil filter.
  • Replace with the correct type and amount of new oil as per manufacturer specifications.
  • Dispose of old oil and filter according to local regulations.
