Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, screwdriver set, cleaning supplies, safety gloves.
Disconnect the battery to prevent electrical shorts and ensure safety while working on the throttle system.

2. Inspect Throttle Cable or Wiring

Remove the engine cover if applicable.
Locate the throttle cable or electrical connector for the throttle body.
Check for fraying, binding, or disconnection.
If damaged, replace the throttle cable or wiring harness.

3. Clean the Throttle Body

Tools Required: Throttle body cleaner, clean cloth.
Remove the throttle body from the intake manifold by unscrewing the mounting bolts.
Spray throttle body cleaner inside the throttle body and use a clean cloth to wipe away carbon deposits and dirt.
Ensure the throttle plate moves freely after cleaning.

4. Replace Throttle Position Sensor (if necessary)

If TPS readings were faulty, remove the old TPS by unscrewing it from the throttle body.
Install the new TPS and ensure it is aligned correctly.
Reconnect the electrical connector.

5. Reassemble and Reconnect

Reinstall the throttle body and torque the bolts to the manufacturer's specifications (typically around 10-15 ft-lbs).
Reconnect the battery and any other components removed during disassembly.
