Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the battery to prevent electrical shorts while working.
2. Address Fault Codes
  • Use the OBD-II scanner to read fault codes and note them down.
  • Research the codes to determine the faulty components or systems.
3. Inspect and Replace Components
  • Air Filter:
    • Remove the air filter housing.
    • Replace the air filter if dirty or clogged.
  • Spark Plugs:
    • Remove the ignition coils.
    • Replace spark plugs with OEM parts, ensuring proper gap settings.
  • Gas Cap:
    • Inspect the gas cap for cracks or damage.
    • Replace with a new one if necessary, ensuring it seals properly.
4. Electrical System Check
  • Battery:
    • Use a multimeter to test the battery voltage (should be around 12.6 volts).
    • Replace the battery if voltage is low or if it shows signs of corrosion.
  • Charging System:
    • Start the vehicle and measure voltage across the battery terminals; should be between 13.7-14.7 volts while running.
    • Replace the alternator if voltage is outside this range.
5. Reassemble and Test
  • Reconnect the battery.
  • Clear the error codes using the OBD-II scanner.
  • Start the engine and monitor for any warning lights or unusual behavior.
