SUBJECT: GM Drive by Wire Throttle Body Cleaning Procedure and Relearn Procedures

---------------------------------------------------------------------------------------------------------------------------------------------------

I have been receiving a lot of calls at the Tech Support Line about proper throttle body cleaning

procedures on various vehicles. Please find the first in a series of Manufacturer’s Recommended

Procedures.

For the model year 2007, GM has 66 named vehicles, not including Isuzu, Saab, and Suzuki im-

ports. There is no wonder there is confusion out there. While the cleaning procedure is pretty normal

across the board with GM, there are 6 different relearn procedures listed, and a lot that require no relearn

at all. Below is the procedure for cleaning. The following pages include a list by name of which proce-

dures to use. This is a comprehensive list for the model year 2007. Older or newer vehicles could differ.

Throttle Body Cleaning

Important: Over extended time and mileage, deposits may accumulate on the back of the throttle

valve plate. The source of the deposit is exhaust gas recirculation (EGR) gas. Typically these depos-

its pose no problem. Occasionally the deposit may accumulate to a point where perceived pedal ef-

fort or throttle valve movement is effected. This procedure should not be performed on vehicles with

mileage under 80 450 km (50,000 mi).

1. Remove the air intake duct. Refer to Air Cleaner Inlet Duct Replacement .



Caution: Turn OFF the ignition before inserting fingers into the throttle bore. Unexpected

movement of the throttle blade could cause personal injury.

Notice: Do not insert any tools into the throttle body bore in order to avoid damage to the

throttle valve plate.

2. 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.



Notice: Do not use any solvent that contains Methyl Ethyl Ketone (MEK). This solvent may

damage fuel system components.

3. Clean the throttle body bore and the throttle valve plate using a clean shop towel with ETech

Chemicals ET110 Throttle Body Cleaner.



4. Install the air intake duct. Refer to Air Cleaner Inlet Duct Replacement.

5. Perform the Throttle Learn Procedure. Refer to Throttle Learn.
