Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and the engine is cool.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, socket set.
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner onto the throttle plate and surrounding area.
Use a soft cloth to gently wipe away carbon buildup and debris.
Open and close the throttle plate manually to ensure it operates freely.
Reconnect the air intake duct.

3. Inspect and Adjust Throttle Cable

Tools Required: Socket set, pliers.
Locate the throttle cable at the throttle body.
Check for any signs of wear or binding; replace if frayed.
If adjustable, ensure proper tension is maintained without being overly tight.

4. Test the Throttle Position Sensor

Tools Required: Multimeter.
Disconnect the throttle position sensor connector.
Set the multimeter to measure voltage.
Check the output voltage while slowly moving the throttle pedal; it should change smoothly.
Replace the sensor if the readings are erratic or outside manufacturer specifications.

5. Reassemble and Reconnect

Reconnect any components removed during the cleaning and inspection process.
Reconnect the negative battery terminal.
Start the vehicle and allow it to idle for a few minutes.
