How to Reprogram a throttle body pontiac G6?
Refer to Diagnostic Trouble Code (DTC) List – Vehicle.
- Start and idle the engine in PARK for 3 minutes.
- With a scan tool, monitor desired and actual RPM.
- The ECM will start to learn the new idle cells and Desired RPM should start to decrease.
- Ignition OFF for 60 seconds.
- Start and idle the engine in PARK for 3 minutes.
How to clean the throttle of a Pontiac G6?
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.
How long does it take for GM throttle body to relearn?
If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle. It will eventually learn it on its own, but it may take over a week of driving, during which time you will experience high and low idle speeds and possibly rough idle. 1) Start the engine and let it idle in park for 3 minutes.
What happens when you replace the throttle body?
If you replace the throttle body, the PCM won’t know and will continue to use the adaptive settings as if the carbon buildup is still in place. If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle.
How does the throttle plate work on a GM car?
A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request. Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position.

What happens when the throttle plate is cleaned?
Perform the Throttle Learn Procedure. Refer to Throttle Learn. The engine control module (ECM) learns the idle position of the throttle plate to ensure the cor- rect idle. Anytime the throttle body is cleaned or replaced, the ECM must learn the new throttle position. The idle may be unstable or a DTC may set if the throttle position is not learned.
What do you need to know about throttle body bore?
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.
