Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety during repairs.
Allow the engine to cool down if it has been running.

2. Inspect the Throttle Pedal Assembly

Remove any floor mats or obstructions around the throttle pedal.
Check for loose connections or debris around the pedal mechanism.
Clean the area with a soft cloth to remove dirt or obstructions.

3. Check and Clean the Throttle Body

Remove any air intake ducting connected to the throttle body using a socket set.
Inspect the throttle body for carbon buildup and clean it with throttle body cleaner.
- Spray the cleaner directly into the throttle body while manually actuating the throttle plate.
Reattach the air intake ducting securely.

4. Examine the Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and inspect for corrosion or damage.
Using a multimeter, check the resistance across the sensor terminals while moving the throttle plate.
- Compare readings with manufacturer specifications.
Replace the sensor if readings are outside acceptable ranges.

5. Reconnect Battery and Test

Reconnect the vehicle's battery.
Start the vehicle and check for any error codes using the OBD-II scanner.
Test the throttle pedal for proper function and ensure it returns to the idle position.
