How to perform a throttle body relearn procedure on Nissan
Perform a throttle body relearn procedure any time you clean an electronic throttle body, disconnect the electrical connector from the throttle body, disconnect the battery, or power down the ECM you must so the ECM/PCM can establish a new fully closed position.
If you have a scan tool, follow the directions included with the tool. If you don’t have a scan tool, follow this procedure
1.Start the engine and let it run until the coolant temp reaches at least 149°.
2.Turn ignition switch to the OFF position and wait at least 10 seconds. Listen or visually check that the throttle valve moves during the 10-second period.
Check that throttle valve moves during the above 10 seconds by confirming the operating sound.
