Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical components.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver set, safety goggles.
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner onto a soft cloth and wipe the inner surfaces of the throttle body.
Open the throttle plate manually to clean both sides thoroughly.
Ensure no cleaner residue is left and allow it to dry.

3. Inspect and Test the Throttle Position Sensor

Tools Required: Multimeter.
Locate the throttle position sensor on the throttle body.
Disconnect the sensor’s electrical connector.
Measure the voltage output at the sensor while slowly moving the throttle from closed to wide open.
Compare the readings to the specifications in the service manual (typically 0.5V at closed and around 4.5V at full throttle).
If the readings are outside the specified range, replace the throttle position sensor.

4. Check the Throttle Cable (if applicable)

If your model has a throttle cable, inspect it for any signs of wear or binding.
Ensure it moves freely without any obstructions.
If damaged, replace the throttle cable with a new one.

5. Reassemble and Reconnect

Reattach the air intake duct securely.
Reconnect the battery and ensure all connectors are tight.
Start the engine and allow it to idle for a few minutes to reset the throttle position learning.
