Solution

1. Preparation

• Gather 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. Inspect and Clean Throttle Body

• Tools Required: Socket set, throttle body cleaner, soft brush, clean rags.
• Remove the air intake duct from the throttle body.
• Spray throttle body cleaner into the throttle body while moving the throttle plate open and closed manually.
• Use a soft brush to gently clean any carbon buildup.
• Wipe the throttle body clean with a rag and ensure it is free of debris.
• Reinstall the air intake duct securely.

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

• Tools Required: Multimeter, screwdriver set, new throttle position sensor.
• Disconnect the electrical connector from the throttle position sensor.
• Using a multimeter, measure the resistance of the TPS according to the manufacturer's specifications.
• If the TPS is out of specification, remove the sensor using a screwdriver and replace it with a new one.
• Reconnect the electrical connector and ensure it is secure.

4. Inspect and Adjust Throttle Cable

• Tools Required: Socket set, pliers.
• Locate the throttle cable at the throttle body and accelerator pedal.
• Check for any signs of wear, fraying, or binding.
• If the cable is damaged, remove it using pliers and replace it with a new throttle cable.
• Adjust the cable tension as per the manufacturer’s specifications to ensure it has the proper amount of slack.

5. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the engine and allow it to idle for a few minutes.
• Test the throttle response by gently pressing the accelerator pedal and observing engine behavior.
