Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery's negative terminal to prevent electrical shorts.

2. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth, socket set.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reattach the air intake duct securely.

3. Inspect and Replace Throttle Position Sensor (If Necessary)

Tools Required: Multimeter, socket set, replacement throttle position sensor.
Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and remove the sensor using a socket set.
Test the new TPS with a multimeter to ensure it meets specifications before installation.
Install the new TPS, reconnect the electrical connector, and ensure it is properly secured.

4. Inspect and Repair Accelerator Pedal Position Sensor

Tools Required: Socket set, multimeter.
Locate the accelerator pedal position sensor under the dashboard near the accelerator pedal.
Inspect the wiring and connectors for damage or corrosion.
If the sensor is faulty, remove it using a socket set and replace it with a new one.
Reconnect the wiring harness, ensuring a secure connection.

5. Verify and Clear Error Codes

Reconnect the battery's negative terminal.
Use the OBD-II scanner to clear any error codes stored in the vehicle's computer.
Perform a test drive to ensure throttle response has improved.
