Solution

1. Preparation

Gather tools including an OBD-II scanner, socket set, multimeter, and tire pressure gauge.
Allow the engine to cool down before beginning any work.
Disconnect the battery for safety when working on electrical components.

2. Address Engine Trouble Codes

Use the OBD-II scanner to retrieve and document any error codes.
Research and address the specific issues indicated by the codes (e.g., replacing a faulty sensor).

3. Change Engine Oil

Drain the old engine oil using a socket set to remove the oil pan bolt.
Replace the oil filter using an oil filter wrench.
Refill with the manufacturer-recommended oil type and capacity.

4. Replace Air Filter

Locate the air filter housing and unsnap or unbolt the cover.
Remove the old air filter and clean any debris from the housing.
Install a new air filter, ensuring it fits securely.

5. Inspect and Repair Fuel System

Check fuel lines for any signs of wear or leaks and replace damaged sections.
Clean or replace fuel injectors using a fuel injector cleaning kit if necessary.

6. Examine the Cooling System

Check the coolant level and top off with the appropriate coolant mix if low.
Inspect the thermostat for proper operation by testing it in hot water.
Replace the thermostat if it does not open at the specified temperature.

7. Check Tire Pressure

Use a tire pressure gauge to measure each tire’s pressure.
Inflate tires to the recommended PSI as stated in the owner’s manual.
