Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Throttle Body Cleaning

Remove the air intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reinstall the air intake duct and secure it properly.

3. Accelerator Pedal Position Sensor Inspection

Locate the accelerator pedal position sensor, usually mounted near the throttle pedal.
Disconnect the sensor connector.
Use a multimeter to check the resistance of the sensor while moving the pedal from rest to full throttle. Resistance values should change smoothly.
If the readings are erratic or out of specification, replace the sensor.

4. Cruise Control System Check

Inspect the cruise control module for proper installation and connections.
Test the cruise control switch for functionality.
If malfunctioning, replace the cruise control module.

5. Final Assembly and Battery Connection

Reconnect the negative battery terminal.
Ensure all components are secured and there are no loose connections.
Start the vehicle and allow it to idle.
