Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before starting the work.

2. Inspect and Clean Throttle Body

Tools Required: Throttle body cleaner, soft brush, rags.
Remove the air intake duct to access the throttle body.
Spray throttle body cleaner into the throttle body and scrub with a soft brush.
Wipe clean with a rag and ensure no cleaner residue remains.
Reinstall the air intake duct securely.

3. Check Throttle Cable

Tools Required: Socket set.
Locate the throttle cable at the throttle body and ensure it is not pinched or frayed.
Adjust the throttle cable tension as needed according to factory specifications.
Lubricate the cable with a suitable lubricant to ensure smooth movement.

4. Test Throttle Position Sensor

Tools Required: Multimeter.
Disconnect the electrical connector from the TPS.
Set the multimeter to the resistance setting.
Measure the resistance across the TPS terminals while moving the throttle plate.
Replace the TPS if resistance readings are inconsistent or outside specifications.

5. Reassemble and Final Checks

Reconnect any components removed during the inspection.
Reconnect the negative battery terminal.
Start the engine and allow it to idle to check for smooth throttle operation.
