Solution

1. Preparation

Gather tools and materials including an OBD-II scanner, multimeter, socket set, and a torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety before working on electrical components.

2. Air Filter Replacement

Remove the air intake duct by loosening the clamps with a socket set.
Take out the air filter and inspect for dirt and debris; replace if necessary.
Reinstall the intake duct, ensuring all clamps are tightened evenly.

3. Transmission Fluid Inspection and Change

Remove the transmission dipstick and check fluid level; add fluid if low.
If the fluid appears dark or burnt, drain and replace the transmission fluid.
- Use a socket set to remove the transmission pan bolts.
- Clean the pan and replace the filter if applicable.
- Refill with manufacturer-recommended transmission fluid.

4. Throttle Position Sensor Testing

Locate the throttle position sensor on the throttle body.
Disconnect the sensor and use a multimeter to check voltage output as per the service manual specifications.
Replace the sensor if it does not meet the required voltage readings.

5. Fuel System Evaluation

Connect a fuel pressure gauge to the fuel rail and turn the ignition to the "ON" position without starting the engine.
Check if the fuel pressure is within specifications; replace the fuel pump if pressure is inadequate.
Inspect fuel lines for leaks or damage.

6. Spark Plug and Ignition System Inspection

Remove spark plug wires and pull out the spark plugs using a socket wrench.
Inspect the spark plugs for wear or deposits; replace if necessary.
Check ignition coils for proper operation using a multimeter and replace any faulty components.
