Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, cleaning solution, throttle body cleaner.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Throttle Body

Remove the air intake duct from the throttle body using a socket set.
Disconnect the throttle body electrical connectors.
Remove the throttle body mounting bolts with the socket set.
Carefully detach the throttle body from the intake manifold.
Inspect for carbon buildup and clean the throttle body using throttle body cleaner and a soft cloth.
Ensure the throttle plate opens and closes smoothly without binding.

3. Replace Throttle Position Sensor (if necessary)

If the TPS is found faulty, remove the throttle body as described in the previous step.
Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector from the TPS.
Remove the screws securing the TPS and replace it with a new one.
Reconnect the electrical connector securely.

4. Reassemble Components

Reinstall the throttle body onto the intake manifold, ensuring the gasket is in good condition.
Secure the throttle body with mounting bolts and torque to manufacturer specifications (refer to the service manual).
Reconnect the air intake duct and ensure all clamps are tightened.

5. Reconnect Battery and Perform Calibration

Reconnect the battery terminal.
Start the engine and allow it to idle for a few minutes to ensure the throttle body recalibrates.
