how to fix a sticking throttle in my Toyota RAV4 XA50 (2019-2024)

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the negative battery terminal to prevent accidental electrical issues.

2. Throttle Body Cleaning

1. Remove the Throttle Body:

   • Disconnect the air intake duct by loosening the clamps and removing it.
   • Unplug the electrical connector from the throttle body.
   • Remove the bolts securing the throttle body using an appropriate socket.
   • Carefully detach the throttle body from the intake manifold.

2. Clean the Throttle Body:

   • Use throttle body cleaner and a clean rag or brush.
   • Spray the cleaner onto the throttle plate and inside the throttle body.
   • Gently scrub to remove carbon buildup, ensuring not to damage any internal components.

3. Reinstall the Throttle Body:

   • Position the cleaned throttle body back onto the intake manifold.
   • Secure it with the bolts to the specified torque (typically around 10-15 ft-lbs, check specifications).
   • Reconnect the electrical connector and reattach the air intake duct.

3. Throttle Cable Inspection and Adjustment

1. Inspect the Throttle Cable:

   • Follow the throttle cable from the accelerator pedal to the throttle body.
   • Look for any signs of fraying, kinks, or binding.

2. Adjust the Throttle Cable:

   • If the cable is adjustable, ensure there is a small amount of slack when the accelerator is not pressed (usually 1-2 mm).
   • Adjust as necessary to ensure smooth operation.

4. Testing

• Reconnect the negative battery terminal.
• Start the engine and check for proper throttle operation.
• Test drive the vehicle to ensure the throttle returns to idle correctly.
