Solution

1. Preparation

Gather necessary tools including an OBD-II scanner, multimeter, basic hand tools, and a torque wrench.
Ensure the vehicle is parked on a level surface, and the ignition is turned off.
Disconnect the negative battery terminal for safety.

2. Inspect and Test Accelerator Pedal Position Sensor

Locate the accelerator pedal position sensor under the pedal assembly.
Disconnect the wiring harness from the sensor.
Using a multimeter, test the resistance of the sensor according to manufacturer specifications (typically between 1kΩ and 5kΩ).
If the readings are outside the specified range, replace the sensor.

3. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Refer to the owner's manual to identify the fuse related to the throttle control.
Inspect the fuse; replace it if it is blown.

4. Inspect Wiring and Connections

Visually inspect the wiring harness for any frays, cuts, or disconnections.
Repair any damaged wires and securely reconnect any loose connections.
Ensure that all connectors are clean and free from corrosion.

5. Check Throttle Body Operation

Remove the air intake duct to access the throttle body.
Inspect the throttle body for carbon buildup or physical obstructions.
Clean the throttle body using throttle body cleaner and a soft cloth.
Reassemble the intake duct securely.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check for warning lights.
Test the accelerator pedal functionality to confirm resolution.
