Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool if it has been running.

2. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
- Tools Required: Socket set, screwdrivers.
Clean the throttle body using throttle body cleaner and a soft brush.
- Ensure the throttle plate moves freely.
Reinstall the air intake duct securely.

3. Inspect and Replace Accelerator Pedal Position Sensor (if faulty)

Locate the accelerator pedal position sensor, typically mounted on the pedal assembly.
Disconnect the electrical connector from the sensor.
Remove the sensor using the appropriate socket or screwdriver.
Install the new accelerator pedal position sensor and reconnect the electrical connector.
- Tools Required: Socket set.
Clear any diagnostic trouble codes from the ECM.

4. Check for Software Updates

Use an OBD-II scanner or manufacturer-specific scan tool to check for available ECM updates.
If updates are available, follow the manufacturer’s procedure for reprogramming the ECM.
