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 electric throttle control actuator in regulating throttle opening in order for idle position to be within plus or minus 10 degrees. Also, ECM regulates an opening speed of about 5 seconds for 10 degrees. Therefore, acceleration will be poor.
