The ECM will start at 29 seconds to cycle the throttle plate from rest position to full closed, then from the full closed position to around 14 percent. This will take about 3 seconds. The ECM will then return the throttle to the rest position. During this throttle plate cycle, the ECM will have learned the lower and rest position TP sensor values, actuator motor torque to overcome spring pressure as well as both spring return rates.
