Solution
1. Preparation
  • Gather necessary tools and parts before starting the repair.
  • Disconnect the negative terminal of the battery to prevent electrical shock.
2. Address Fault Codes
  • Use the OBD-II scanner to retrieve codes. Note the codes for reference.
  • Research the specific code(s) to determine the necessary repairs.
3. Inspect and Replace Components

A. Gas Cap

  • Tools Required: None
  • Ensure the gas cap is properly tightened. If damaged, replace with a new gas cap.

B. Ignition Components

  • Tools Required: Socket set, torque wrench
  1. Remove the engine cover if applicable.
  2. Disconnect the negative battery terminal.
  3. Remove spark plug wires by pulling straight out.
  4. Use a socket to remove the spark plugs; check for wear and replace if necessary.
  5. Inspect ignition coils for any cracks or signs of damage; replace if needed.
  6. Reassemble components, ensuring all bolts are torqued to manufacturer specifications.
4. Air Filter Replacement
  • Tools Required: None (if no additional tools are required for the housing)
  1. Locate the air intake housing.
  2. Open the housing and remove the old air filter.
  3. Install a new air filter, ensuring it fits snugly in place.
  4. Close the housing securely.
5. Battery and Charging System Check
  • Tools Required: Multimeter
  1. Reconnect the negative battery terminal.
