Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the negative battery terminal to ensure safety during diagnostics and repairs.
2. Retrieve Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Turn the ignition to the "On" position without starting the engine.
  • Retrieve and note any error codes displayed on the scanner for further analysis.
3. Inspect and Address Issues
  • Engine Oil:

    • Check the engine oil level and condition.
    • If low or dirty, change the oil and replace the oil filter according to the manufacturer’s specifications (typically 5W-30 synthetic oil).
  • Fuel System:

    • Use a fuel pressure gauge to test the fuel system pressure.
    • If pressure is low, inspect and replace the fuel filter and fuel pump if necessary.
  • Air Intake:

    • Visually inspect the air filter and intake ducts for blockages or damage.
    • Replace the air filter if dirty or clogged.
  • Ignition System:

    • Remove the spark plugs and inspect for wear or carbon buildup.
    • Replace any worn or fouled spark plugs and ignition coils as necessary.
4. Clear Error Codes
  • After addressing the issues, reconnect the OBD-II scanner.
  • Clear the error codes from the vehicle’s computer and reset the service engine soon light.
5. Reconnect Battery
