Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
Steps:
1. Remove the air intake duct connected to the throttle body using a screwdriver.
2. Spray throttle body cleaner onto a soft cloth.
3. Wipe the throttle body interior, ensuring to remove all carbon deposits and dirt.
4. Reattach the air intake duct securely.

3. Test and Replace the Throttle Position Sensor

Tools Required: Multimeter, socket set.
Steps:
1. Locate the throttle position sensor on the throttle body.
2. Disconnect the electrical connector from the TPS.
3. Use a multimeter to check the voltage output of the TPS while moving the throttle plate.
4. If readings are inconsistent or outside the manufacturer's specifications, replace the TPS.
5. Install the new TPS and reconnect the electrical connector.

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

Tools Required: Socket set.
Steps:
1. Locate the accelerator pedal position sensor under the dashboard.
2. Remove the connector and unbolt the sensor from the assembly.
3. Install the new sensor and reconnect the electrical connector.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any stored trouble codes.
