Sub-step 2: Research the codes to determine the necessary repairs.
Sub-step 3: Clear codes after repairs to reset the check engine light.

3. Inspect and Replace Air Filter

Sub-step 1: Locate the air filter housing and remove the cover.
Sub-step 2: Take out the old air filter and inspect it for dirt and damage.
Sub-step 3: Install a new air filter, ensuring it is seated properly.
Tools Required: Screwdriver or socket set.

4. Fuel System Inspection

Sub-step 1: Connect the fuel pressure gauge to the fuel rail.
Sub-step 2: Start the engine and check for the specified fuel pressure (consult manufacturer specifications).
Sub-step 3: If pressure is low, check the fuel pump and replace if necessary.

5. Inspect and Replace Spark Plugs

Sub-step 1: Remove the ignition coils and spark plugs using a socket set.
Sub-step 2: Inspect the spark plugs for wear or damage.
Sub-step 3: Replace with new spark plugs, ensuring proper gap and torque settings.
