How to do a GM throttle body relearn procedure If you've replaced your GM electronic throttle body or you've disconnected the battery, you must do a GM throttle body relearn to establish a new baseline idle. Many car makers including GM started installing fly by wire electronic throttle bodies. In those vehicles, the 'gas' pedal isn't connected to the throttle body by a cable. The pedal simply provides an electronic signal, telling the throttle body how much acceleration you're requesting. A motor and gear reduction set inside the throttle body … Read More

When integrating the GM harness, it was necessary to undo a few of the connectors, such as the OBD-II and fly-by-wire throttle pedal plugs, for interior vehicle access without having to cut huge. File dump sw tanaka t22 jurasic. Throttle Body and Accelerator Pedal With a few exceptions, the electronic throttle body is very similar to a cable-operated throttle body. One of the most noticeable exceptions is the addition of the throttle actuator control (TAC) motor. This is used to open and close the throttle plate based on commands from the ECM. My dads truck is 2 for 3. Replaced the gas pedal assembly, and the throttle body harness, and re crimped them. Thought it was fixed, but its not. So now the dealer has the truck again and they're not sure what they are gonna do. Replace the throttle body i guess. I told my dad to get into an accident because of the reduced engine power, then.

How to do a GM throttle body relearn procedure

If you've replaced your GM electronic throttle body or you've disconnected the battery, you must do a GM throttle body relearn to establish a new baseline idle. Many car makers including GM started installing fly by wire electronic throttle bodies. In those vehicles, the 'gas' pedal isn't connected to the throttle body by a cable. The pedal simply provides an electronic signal, telling the throttle body how much acceleration you're requesting. 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. If the buildup occurs gradually, the PCM 'learns' the new home position. But when your battery goes dead or you disconnect it to work on your vehicle, the PCM 'forgets' the adapative home position. 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. 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.

Here's the throttle body relearn procedure

1) Start the engine and let it idle in park for 3 minutes. During that period the idle may be higher idle than normal.
2) After 3 minutes, turn the engine off and leave it off for 60- seconds.
3) Start the engine again and let it idle in park for 3 minutes one more time. During these run periods you may see a check engine light. Scan for codes and if you get throttle body related codes, clear them.
4) If the idle speed is still off, drive the vehicle at speeds above 44-mph and operate several acceleration and deceleration cycles. Then repeat step #3 one last time.

The idle should now be normal
