You may notice a higher incorrect idle speed until the ECM.
When to do idle relearn?
In the event you are experiencing an erratic idle after loading a tune or after performing any action that clears KAM (Keep Alive Memory), an Idle Relearn can help you get back on track. The KAM or “Keep Alive Memory” is the memory that is stored in the powertrain control module (PCM).
How do I adjust the idle on my electronic throttle control?
Disconnect the idle air adjustment valve by locating and disengaging the electronic connector that holds it to the throttle body. Turn the idle screw to adjust the idle—turn the screw to the left to increase the RPM or to the right to lower it.
How do you reset throttle body after replacing?
Leave the key off for a moment, turn the key to the "On" position again, wait 3 seconds, and press the accelerator 5 times in 5 seconds. Wait 7 seconds, and hold the accelerator down. The check engine light should start blinking, continue to hold pedal down until it stops blinking. You can then start the car.
How do you calibrate?
Windows. On Windows, open the Control Panel and search for "calibrate." Under Display, click on "Calibrate display color." A window will open with the Display Color Calibration tool. It steps you through the following basic image settings: gamma, brightness and contrast, and color balance.
What happens if you replace 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.
What is a fly by wire throttle body?
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.
What happens to the PCM when the battery goes dead?
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.
How do you recalibrate a throttle body?
Make sure that the accelerator pedal is fully released. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds. Turn ignition switch “ON” and wait at least 2 seconds.
What is the ford fusion throttle body reset procedure?
The Ford Fusion’s throttle body must be “re-trained” by parking the vehicle on a flat surface, applying the parking brake, and shifting the transmission into park. Turn off all of your accessories. Start the engine and let it run until it reaches operating temperatures, then turn off the engine and let it idle for at least one minute. Turn on the air conditioning and allow it to run for another minute or so. Release the parking brake while leaving your foot firmly planted on the brake pedal and the air conditioning turned on.
How do I reset my throttle position sensor?

How do you reset the computer on a Ford f150?
Loosen the lock nut located on the negative battery cable connector with a socket and ratchet. Pull the connector off the negative battery terminal. Wait for 20 minutes while the PCM bleeds off the electricity it stores for backup power. Once the power drains from the PCM, it resets.
What temperature should the throttle body be before doing a TBA?
There are certain test conditions that must be met before doing a TBA: No DTC's in the Engine Controller. Battery voltage at least 11.5 V. Throttle must be at idling position (keep your foot off the gas pedal) Throttle body part must not be dirty (carbonized). Coolant temperature must be between 5 and 95C.
How long does TB cycle?
The TB may cycle for the first few seconds then it will stop. Leave it in Basic Settings for about 30 seconds.
What causes a TBA to fail?
On vehicles that use Cable-Throttle systems, an over adjusted (or sticky) throttle cable can cause the TBA to fail, or symptoms like no CCS (Cruise Control System) operation.
How long to leave TB on?
The TB adaptation is being done as soon as you switched basic settings on. You will see the values change and hear the TB cycle for the first few seconds then it will stop. Leave it in Basic Settings for about 30 seconds.

Does Ross Tech do TBA?
Ross-Tech is not responsible for any damage or problems that may result from following these instructions. They are to be used at your own risk. As always, you should refer to a Factory Repair Manual for your vehicle!#N#This procedure details how to perform a Throttle Body Alignment (TBA) on many VW/Audi vehicles with Gasoline engines. This procedure cycles the motorized throttle body through various states (idle, part throttle, WOT) to relearn their positions. Some examples of reasons to perform a TBA:
Has the ECU been removed?
The ECU has been removed and reinstalled. The Throttle Body has been cleaned or removed and reinstalled. The Accelerator Pedal has been removed and reinstalled. In some vehicles, the car will not run correctly, or may not run at all without performing a TBA after one of the above operations.
Causes of high idle after cleaning throttle body
Mass airflow sensor accurately measures the air quantity that is going into the engine inside the throttle body. A vacuum leak could occur when the throttle body permits more air into the machine, and the computer is compensating by adding more fuel.
How to fix high idle after cleaning throttle body
You should note that the idle shall be high at first until the computer relearns it again.
Conclusion
Cleaning the throttle body enables smooth running of the car. If done incorrectly, it causes high idling, which is caused by vacuum leaking, torn intake horse, debris in the throttle bore, and computer readjusting. Each of the problems has its effects that have homemade solutions, while some require certified mechanics.
