Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.
Gather tools: socket set, screwdrivers, and a multimeter.

2. Inspect Throttle Cable

Locate the throttle cable attached to the throttle body.
Check for fraying, kinks, or binding along its length.
If damaged, remove the cable by:
- Loosening the retaining bracket bolts.
- Disconnecting the cable from the throttle body.
Replace with a new throttle cable if necessary.

3. Clean Throttle Body

Remove the air intake duct connecting to the throttle body.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
Ensure the throttle plate moves freely without obstruction.
Reattach the air intake duct securely.

4. Test Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Disconnect the wiring harness.
Use a multimeter to check the voltage output of the TPS while moving the throttle plate.
Compare readings to manufacturer specifications (typically 0.5V at idle and up to 4.5V at wide open throttle).
Replace the TPS if readings are out of spec.

5. Reassemble and Test

Reconnect the battery.
Start the engine and observe throttle response.
Test drive the vehicle to ensure proper throttle function.
