Solution

1. Preparation

Tools Required: OBD-II scanner, screwdriver set, throttle body cleaner, multimeter, torque wrench.
Disconnect the battery to prevent electrical shorts.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a screwdriver.
Spray throttle body cleaner into the throttle body while manually opening the throttle plate.
Wipe excess carbon buildup with a clean cloth.
Reattach the air intake duct securely.

3. Inspect and Test the Throttle Position Sensor (TPS)

Locate the TPS on the throttle body and disconnect the electrical connector.
Use a multimeter to check the TPS voltage; it should vary smoothly from 0.5V to 4.5V when the throttle is opened.
If the readings are inconsistent or outside specifications, replace the TPS.

4. Check the Accelerator Pedal Position Sensor

Disconnect the accelerator pedal connector.
Measure the resistance using a multimeter while pressing the pedal.
Confirm the resistance values match the manufacturer specifications. Replace if faulty.

5. Update ECU Software (if necessary)

Connect the OBD-II scanner and check for available updates.
Follow the manufacturer’s instructions to update the ECU software as needed.
