Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool if it has been running.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner onto a soft cloth and clean the inside of the throttle body to remove carbon deposits.
Ensure the throttle plate moves freely and reassemble the intake duct.

3. Replace Throttle Position Sensor (if necessary)

Tools Required: Socket set, torque wrench.
Disconnect the electrical connector from the TPS.
Remove the screws securing the TPS to the throttle body using the socket set.
Install the new TPS in the same position as the old one and torque to manufacturer specifications.
Reconnect the electrical connector.

4. Inspect and Replace Accelerator Pedal Position Sensor (if necessary)

Tools Required: Socket set, multimeter.
Remove any panels obstructing access to the accelerator pedal position sensor.
Disconnect the electrical connector and remove the sensor.
Test the new sensor with a multimeter to ensure it operates within specifications.
Install the new sensor and reconnect the electrical harness.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored trouble codes.
Start the engine and allow it to idle for a few minutes.
