Solution

1. Preparation

Gather the necessary tools and parts.
Disconnect the negative battery terminal to avoid any electrical shorts during repair.

2. Inspect and Clean Throttle Body

Remove the engine cover if necessary.
Detach the air intake ducting from the throttle body.
Tools Required: Socket set, throttle body cleaner, clean cloths.
Spray throttle body cleaner onto a clean cloth and wipe the throttle body to remove carbon deposits.
Open the throttle plate manually to clean inside thoroughly.
Reattach the air intake ducting securely.

3. Replace Throttle Position Sensor (if necessary)

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector from the TPS.
Remove the mounting screws and lift the sensor off.
Install the new throttle position sensor and secure with screws.
Reconnect the electrical connector.

4. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes that may have been logged.
Start the vehicle and allow it to idle for a few minutes to recalibrate the throttle system.
