Solution

1. Preparation

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

2. Inspect and Clean the Throttle Body

Tools Required: Throttle body cleaner, screwdriver set, soft cloth, torque wrench.
Remove the air intake duct from the throttle body by loosening the hose clamps.
Disconnect the throttle body electrical connector and remove the mounting bolts.
Carefully remove the throttle body and inspect for carbon buildup.
Clean the throttle body with throttle body cleaner and a soft cloth, ensuring the throttle plate moves freely.
Reinstall the throttle body and torque the bolts to the manufacturer’s specifications.

3. Check Accelerator Pedal Position Sensor

Inspect the accelerator pedal position sensor’s connector for damage or looseness.
If necessary, remove the sensor and test it using a multimeter to ensure it provides the correct voltage output when the pedal is depressed.
Replace the sensor if the output is outside of the manufacturer’s specified range.

4. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any diagnostic trouble codes stored in the system.

5. Test Drive and Calibration

Start the engine and allow it to idle for a few minutes.
Perform a test drive to ensure throttle response is restored.
If issues persist, perform a throttle body relearn procedure as per manufacturer specifications.
