Do you need to do a Nissan throttle body relearn?
If you own a 2002-2011 Nissan Altima and clean or replace the throttle body or replace the ECU, you must do a Nissan Throttle Body Relearn Procedure to get a proper idle speed. Nissan calls this an Idle Air Volume Learning Procedure You can also perform this procedure if you feel the idle speed it out of spec.
Why does my Nissan Altima idle erratically?
Problem Description. The throttle body for the Nissan Altima is known for carbon buildup, and requires regular, light cleaning to maintain peak performance. After cleaning the throttle body, many owners notice a very high idle, erratic (bouncing) idle, and unpredictable power surging.
What causes high idle after cleaning throttle body?
After cleaning the throttle body, many owners notice a very high idle, erratic (bouncing) idle, and unpredictable power surging. The cause is normal ECU adaptation: When the throttle body builds up carbon, the rate of airflow is slightly decreased.

How to relearn the Nissan throttle body procedure?
Transmission must be warmed up (driven for at least 10 minutes.) 1) Perform the Accelerator Pedal Released Learning procedure. This procedure tells the ECU what voltages to expect when your foot is off the pedal Turn ignition switch OFF and wait at least 10 seconds. Turn ignition switch ON.
How to do idle Relearn on a Nissan Altima?

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 often should you wipe the throttle body?
While it is trying to change settings, the idle will bounce from low to high, and the car will surge forward at times. It has been recommended to simply wipe inside the throttle body every 12,000 miles, and never to touch the flap inside.
