Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Disconnect the vehicle's battery to prevent electrical issues.

Tools Required:

Socket set
Screwdrivers
Multimeter
Throttle body cleaner
Cleaning cloths

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Detach the throttle body from the intake manifold, taking care to remove any bolts or clamps.
Inspect the throttle body for carbon buildup or debris.
Use throttle body cleaner and a cleaning cloth to thoroughly clean the inside of the throttle body.
Ensure the throttle plate moves freely without sticking; if it does, check for wear or damage.

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

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector from the sensor.
Use a multimeter to test the sensor's resistance and voltage output according to manufacturer specifications.
If the readings are outside specifications, replace the throttle position sensor with a new one.
Reconnect the electrical connector securely.

4. Reassemble Components

Reattach the throttle body to the intake manifold, ensuring all bolts are tightened to the manufacturer’s torque specifications.
Reconnect the air intake duct.
Reconnect the vehicle’s battery.
