Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before working on the throttle assembly.

2. Inspect and Clean Throttle Body

Tools Required: Socket set, throttle body cleaner, soft cloth or brush.
Remove the air intake duct connected to the throttle body.
Clean the throttle body with throttle body cleaner and a soft cloth or brush, paying special attention to the throttle plate and surrounding areas.
Inspect the throttle plate for proper movement, ensuring it opens and closes freely.

3. Check and Adjust Throttle Cable

Tools Required: Socket set, pliers.
Locate the throttle cable connection at the throttle body.
Inspect the cable for fraying or binding; replace if necessary.
Adjust the cable tension if applicable, ensuring it has the proper amount of slack.

4. Inspect Throttle Position Sensor

Tools Required: Multimeter, socket set.
Locate the TPS on the throttle body.
Disconnect the electrical connector and use a multimeter to test the TPS resistance while moving the throttle plate.
Replace the TPS if readings are outside manufacturer specifications.

5. Reassemble and Test

Reattach the air intake duct securely.
Reconnect the negative battery terminal.
Start the vehicle and check for throttle operation; ensure it responds correctly throughout the pedal range.
