Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety during work on electrical components.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloths, socket set.
Remove the air intake duct connected to the throttle body.
Spray the throttle body cleaner onto a clean cloth and wipe the throttle body interior, focusing on the throttle plate and surrounding areas.
Open the throttle plate manually to clean behind it, ensuring no cleaner residue remains.

3. Inspect and Replace the Throttle Position Sensor (if necessary)

Tools Required: Multimeter, socket set.
Disconnect the wiring harness from the throttle position sensor.
Use a multimeter to check the sensor’s resistance and output voltage according to the manufacturer’s specifications.
If the sensor is faulty, remove the old sensor and install a new one, ensuring it's calibrated properly.

4. Reassemble Components

Reattach the air intake duct securely to the throttle body.
Reconnect the battery terminals.
Ensure all bolts and clips are tightened to the manufacturer's torque specifications.
