Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, cleaning solvent, soft brush
Disconnect the vehicle battery to ensure safety while working on electrical components.
Allow the engine to cool before starting repairs.

2. Inspect and Clean Throttle Body

Remove the air intake hose connected to the throttle body using a socket set.
Inspect the throttle body for dirt and carbon buildup.
Use a cleaning solvent and a soft brush to clean the throttle body surfaces. Ensure the throttle plate moves freely after cleaning.
Reattach the air intake hose securely.

3. Check and Replace Throttle Cable (if necessary)

Locate the throttle cable on the engine and inspect it for any signs of damage or binding.
If damaged, disconnect the throttle cable from both the throttle body and the accelerator pedal.
Install the new throttle cable by connecting it to the throttle body first, then to the accelerator pedal. Adjust the cable tension if adjustable.

4. Test and Replace Throttle Position Sensor (if necessary)

Disconnect the electrical connector from the throttle position sensor.
Using a multimeter, check the voltage output while opening the throttle manually. It should provide a smooth voltage change.
If the sensor is faulty, remove the old TPS and install the new one, ensuring it is aligned and secured.

5. Reconnect Battery and Verify

Reconnect the vehicle battery.
Start the engine and allow it to idle. Check for any abnormal RPM fluctuations.
Test drive the vehicle to ensure the throttle operates smoothly without sticking.
