Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, screwdrivers, cleaning brush, throttle body cleaner, safety glasses, gloves.
Safety Warnings: Disconnect the battery before working on electrical components.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using the socket set.
Access the throttle body and inspect it for carbon buildup or debris.
Spray throttle body cleaner onto the throttle body and use a cleaning brush to scrub away deposits.
Wipe the throttle body with a clean cloth and let it dry.

3. Inspect and Test the Throttle Position Sensor

Disconnect the throttle position sensor connector.
Use a multimeter to check the voltage output of the TPS while moving the throttle plate.
Ensure the voltage changes smoothly as the throttle opens. If not, replace the TPS.

4. Check the Accelerator Pedal Position Sensor

Locate the accelerator pedal position sensor under the dashboard.
Disconnect the sensor connector.
Test the sensor with a multimeter to ensure it provides the correct resistance values as the pedal is pressed.
If faulty, replace the accelerator pedal position sensor.

5. Reassemble and Reconnect

Reconnect the throttle body and air intake duct, ensuring all clamps are secure.
Reconnect the battery and clear any error codes with the OBD-II scanner.
