Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Clean Throttle Body

Tools Required: Socket set, cleaning brush, throttle body cleaner, rag
Remove the air intake duct to access the throttle body.
Use the throttle body cleaner and a brush to clean the inside of the throttle body.
Ensure no debris falls into the intake manifold during cleaning.
Reinstall the air intake duct securely.

3. Check and Replace Throttle Position Sensor (if necessary)

Tools Required: Socket set, multimeter
Disconnect the electrical connector from the throttle position sensor.
Use a multimeter to check the resistance and voltage output of the TPS according to manufacturer specifications.
If readings are outside specifications, remove the TPS using a socket set and replace it with a new unit.
Reconnect the electrical connector securely.

4. Inspect Accelerator Pedal Assembly

Tools Required: Socket set
Remove the accelerator pedal assembly from its mounting (if binding is suspected).
Inspect for any physical damage or binding in the pivot points.
Lubricate or replace components as necessary and reinstall.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and allow it to idle for a few minutes to reset the ECU.
Test the throttle response by gently pressing the accelerator pedal.
