Does Geely Emgrand need power off to clean the throttle?

Need. Buy a bottle of carburetor cleaner, remove the throttle and clean it. It should be noted that after installation, disconnect the battery for 5 minutes before connecting it, otherwise there will be a fault light prompt. The cleaning steps of the throttle valve are as follows:

1. Turn off the ignition switch and remove the negative electrode of the battery.

2. Remove the throttle pipe, air inlet hose and the screw for fixing the throttle valve in turn.

3. Clean the throttle with cleaning agent, and wipe the parts that cannot be cleaned with cotton thread.
