Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Throttle Body Cleaning

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body while moving the throttle plate manually.
Use a clean rag to wipe away carbon deposits.
Reassemble the air intake duct and reconnect the negative battery terminal.

3. Inspect and Replace Accelerator Pedal Position Sensor

Locate the accelerator pedal position sensor, typically mounted on the throttle pedal assembly.
Disconnect the electrical connector from the sensor.
Remove the mounting screws and take out the old sensor.
Install the new sensor and secure it with screws.
Reconnect the electrical connector and ensure proper alignment.

4. Transmission Fluid Check and Change (if necessary)

Locate the transmission dipstick, usually near the back of the engine bay.
Pull the dipstick out, wipe it clean, and reinsert it to check the fluid level.
If low, add the recommended transmission fluid type (check the owner’s manual).
If the fluid is dark or has a burnt smell, consider performing a transmission fluid change.
