Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool down before working on it.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver set, torque wrench.
Remove the air intake duct connected to the throttle body.
Unbolt the throttle body from the intake manifold using the socket set.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body thoroughly.
Reinstall the throttle body and secure it with the appropriate torque specifications (typically around 15-20 ft-lbs).
Reattach the air intake duct.

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

Tools Required: Socket set, multimeter.
Disconnect the electrical connector from the accelerator pedal position sensor.
Use a multimeter to test the sensor’s resistance across its terminals while manually moving the pedal.
If the readings are outside the manufacturer’s specifications, replace the sensor.
Reinstall the new sensor and reconnect the electrical connector.

4. Check and Reset the Throttle Position

Once repairs are complete, perform a throttle position reset.
Turn the ignition to the "ON" position without starting the engine.
Wait for a few seconds, then press the accelerator pedal fully to the floor and release it.
Start the engine and allow it to idle for a few minutes for the system to calibrate.
