  2. Interpret Codes: Refer to the vehicle’s service manual to understand the meaning of the codes.
  3. Clear Codes: After repairs, clear the codes using the scanner and reconnect the battery.
3. Repair Identified Issues
  1. Gas Cap Replacement (if applicable):

    • Remove the old gas cap and install a new one if it was found faulty.
    • Torque the cap to the manufacturer's specification.
  2. Sensor Replacement (if applicable):

    • If codes indicate a faulty sensor (e.g., oxygen sensor, MAF sensor):
      • Disconnect electrical connectors.
      • Remove the sensor using a socket wrench.
      • Install the new sensor and reconnect the wiring.
  3. Fix Leaks or Damaged Components:

    • If any leaks or damaged hoses are found, replace or repair as necessary.
