Solution

1. Preparation

Gather tools and parts: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, and any required replacement parts.
Ensure safety measures are in place: disconnect the battery before working on electrical systems.

2. Address Error Codes

Connect the OBD-II scanner and retrieve error codes.
Note any codes related to the engine or transmission and address them accordingly.

3. Inspect and Replace Air Filter

Remove the air intake duct using a socket set.
Take out the old air filter and inspect it for dirt and clogs.
Replace with a new OEM air filter, ensuring it fits snugly.

4. Check and Replace Fuel Filter

Locate the fuel filter and relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect fuel lines using the appropriate tools.
Remove the old fuel filter and install a new one, ensuring proper orientation and connections.

5. Transmission Fluid Check

Locate the transmission dipstick or fill plug.
Check the fluid level and condition; it should be a clear red color and at the correct level.
If low or dirty, drain the transmission fluid and replace it with manufacturer-recommended fluid, ensuring to torque the drain and fill plugs to specifications.

6. Exhaust System Inspection

Inspect the exhaust system visually for any signs of damage or blockages.
If a blockage is found, remove the affected section for cleaning or replacement.
