Solution

1. Preparation

Gather tools and parts required.
Disconnect the negative battery terminal to avoid electrical shorts.
Allow the engine to cool down before starting work.

2. Clean Throttle Body

Tools Required: Throttle body cleaner, soft brush, rags.
Remove the air intake duct connected to the throttle body.
Spray the throttle body cleaner into the throttle body and scrub gently with a soft brush.
Wipe clean with a rag to remove any remaining dirt and residue.
Reattach the air intake duct securely.

3. Inspect and Replace Throttle Position Sensor (if necessary)

Tools Required: Socket set, torque wrench.
Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector from the sensor.
Remove the mounting screws and carefully take out the sensor.
Install the new throttle position sensor, tightening the screws to manufacturer specifications (usually around 10-15 ft-lbs).
Reconnect the electrical connector.

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

Tools Required: Socket set, multimeter.
Locate the accelerator pedal position sensor.
Disconnect the wiring harness.
Use a multimeter to check the sensor's resistance as per manufacturer specifications.
If faulty, remove the sensor and install a new one, ensuring it is securely attached.

5. Reconnect Battery and Reset ECU

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