Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery to prevent electrical shorts.
2. Scan and Clear Codes
  • Use an OBD-II scanner to check for stored codes.
  • Write down any fault codes for reference.
  • Clear the fault codes and observe if the engine light returns.
3. Inspect and Replace Components

A. Gas Cap Inspection

  • Check the gas cap for cracks or wear.
  • Replace the gas cap if faulty.

B. Air Filter Replacement

  • Remove the air filter housing cover.
  • Take out the old air filter and install a new one.
  • Ensure the housing is sealed properly before reassembly.

C. Spark Plug and Coil Inspection

  • Remove the ignition coil cover.
  • Disconnect the ignition coils and inspect for cracks or carbon buildup.
  • Replace any faulty coils and spark plugs as needed.
  • Torque spark plugs to manufacturer specifications (typically around 13-17 lb-ft).
4. Battery and Electrical System Check
  • Inspect battery terminals for corrosion and ensure tight connections.
  • Use a multimeter to measure battery voltage; it should be around 12.6 volts when fully charged.
  • Replace the battery if it is below 12.4 volts.
