Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Battery

Tools Required: Socket set, multimeter
Check the battery voltage with a multimeter. If the voltage is below 12.4 volts, the battery may need to be charged or replaced.
If replacing the battery, remove the battery cover and disconnect the positive terminal followed by the negative terminal.
Install the new battery by connecting the positive terminal first, then the negative terminal.
Reinstall the battery cover and reconnect the negative terminal.

3. Check Power Electronics Module

Tools Required: Torque wrench
Remove the access panel to the power electronics module.
Inspect for any signs of damage or overheating.
If damaged, remove the module by unscrewing the mounting bolts with a torque wrench and replace with a new module.
Reinstall the access panel securely.

4. Throttle Position Sensor Replacement

Tools Required: Screwdriver set, torque wrench
Locate the throttle position sensor on the throttle body.
Detach the electrical connector and unscrew the sensor from its mounting.
Replace with a new throttle position sensor, ensuring it is properly aligned.
Reconnect the electrical connector and secure the sensor with mounting screws using a torque wrench.

5. Reconnect Battery and Test

Reconnect the negative battery terminal and ensure it is tight.
Start the vehicle and monitor for any warning lights or unusual behavior.
Perform a test drive to confirm that the stalling issue has been resolved.
