Throttle Valve Closed Position Learning Procedure: Description
WARNING: This page is about a different car, the 2002 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
This operation is used to learn the fully closed position of throttle valve by monitoring throttle position sensor output signal. It must be performed each time electric throttle control actuator harness connector or ECM are disconnected.
