Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, multimeter, fuel injector cleaner.
  • Disconnect the battery to ensure safety before working on electrical components.
2. Address Fault Code
  • Use the OBD-II scanner to retrieve and note the specific fault codes.
  • Research the codes to determine the affected components or systems.
3. Inspect and Replace Spark Plugs
  • Remove the ignition coils using a socket set.
  • Take out the spark plugs; inspect them for wear, carbon buildup, or damage.
  • Replace with OEM or high-quality aftermarket spark plugs if necessary (Torque to manufacturer specifications).
4. Clean or Replace Fuel Injectors
  • If fuel injectors are clogged, use a fuel injector cleaner to clean them.
  • If cleaning does not resolve the issue, remove and replace any faulty injectors.
5. Test and Replace MAF Sensor
  • Disconnect the MAF sensor and use a multimeter to check its voltage output while the engine is running.
  • If the readings are out of specification, replace the MAF sensor.
6. Reconnect and Test
  • Reconnect the battery.
  • Clear the fault codes using the OBD-II scanner.
  • Test drive the vehicle to ensure the check engine light does not reappear.
