Fail-Safe Mode

WARNING: This page is about a different car, the 2002 Nissan Maxima and 2002 Infiniti I35. However, it is still accessible from the selected car via links, so may be relevant.

When malfunction is detected, ECM enters fail-safe mode and MIL illuminates. ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10 degrees. ECM regulates an opening speed of about 5 seconds to an opening of 10 degrees. Therefore, acceleration will be poor.
