Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool down before beginning work.

2. Throttle Body Cleaning

Remove the air intake duct for better access.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Inspect the throttle body gasket and replace if damaged.

3. Throttle Position Sensor (TPS) Replacement

Locate the TPS on the throttle body.
Disconnect the electrical connector.
Remove the mounting screws and take out the old TPS.
Install the new TPS in the correct orientation and secure it with screws.
Reconnect the electrical connector.

4. Accelerator Pedal Position Sensor (APPS) Inspection/Replacement

Remove the screws securing the accelerator pedal assembly.
Disconnect the electrical connector from the APPS.
Inspect the sensor for damage; replace if necessary.
Install a new APPS if required and reconnect.

5. Reassembly and Connection

Reattach the air intake duct and ensure all clamps are secure.
Reconnect the negative battery terminal.
Clear any diagnostic trouble codes using the OBD-II scanner.
