Chevrolet Sonic Repair Manual: Throttle Body Inspection and Cleaning
Note:
Over extended time and mileage, deposits may accumulate on the back of the throttle valve plate. The source of the deposit is exhaust gas. Typically these deposits pose no problem. Occasionally the deposit may accumulate to a point where perceived pedal effort or throttle valve movement is effected.
- Remove the air cleaner outlet duct. Refer to Air Cleaner Outlet Duct Replacement.
- Inspect the throttle body bore and the throttle valve plate for deposits. You will need to open the throttle valve in order to inspect all surfaces.
- Clean the throttle body bore and the throttle valve plate using a clean shop towel with an appropriate cleaner.
- Install the air cleaner outlet duct. Refer to Air Cleaner Outlet Duct Replacement.
