Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the battery to prevent any electrical issues.
  • Ensure the vehicle is on a level surface and safely supported.
2. Inspect Engine Oil
  • Check the oil level using the dipstick.
  • If oil is low, add the manufacturer-recommended oil type to the proper level.
  • If oil is dirty or smells burnt, consider an additional oil change.
3. Check Oil Filter Installation
  • Locate the oil filter and ensure it is properly installed.
  • If it is loose, tighten it by hand until snug, then check for leaks.
  • If damaged, replace it with a new filter.
4. Tighten Oil Drain Plug
  • Locate the oil drain plug on the oil pan.
  • Use a socket wrench to ensure it is securely tightened to manufacturer specifications (typically 20-25 lb-ft).
  • Check for signs of leaking around the plug.
5. Inspect Gas Cap
  • Remove the gas cap and inspect for damage or dirt on the seal.
  • Clean the gas cap and the filler neck with a cloth.
  • Reinstall the gas cap and ensure it clicks securely in place.
6. Clear Error Codes
  • Reconnect the battery.
  • Use the OBD-II scanner to clear any error codes.
  • Start the engine and monitor the check engine light.
