Solution
1. Preparation
  • Gather tools and equipment: OBD-II scanner, socket set, multimeter, and fuel pressure gauge.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Address Diagnostic Trouble Codes
  • Use the OBD-II scanner to identify and document the specific error codes.
  • Research the error codes to determine potential causes and necessary repairs.
3. Inspect and Replace Components
  • Ignition System:

    • Remove the engine cover (if applicable).
    • Replace spark plugs using a torque wrench set to manufacturer specifications (typically 13-15 lb-ft).
    • Test ignition coils with a multimeter for proper resistance; replace if outside specifications.
  • Fuel System:

    • Connect the fuel pressure gauge to the fuel rail.
    • Start the engine and check the fuel pressure; refer to service manual for specifications.
    • Replace the fuel filter if pressure is below specifications or if it has not been changed as per maintenance schedule.
  • Air Intake System:

    • Inspect the air filter and replace if clogged.
    • Check for vacuum leaks in hoses and the intake manifold; replace any damaged hoses.
4. Final Checks
  • Reconnect the battery and reset the check engine light using the OBD-II scanner.
  • Monitor for any reoccurrence of the error codes after repairs.
