Fail Safe Mode

WARNING: This page is about a different car, the 2002 Nissan Pathfinder and 2002 Infiniti QX4. However, it is still accessible from the selected car via links, so may be relevant.

When malfunction is detected, ECM enters fail safe mode. Throttle position will be determined based on the injected fuel amount and engine speed. When in fail safe mode acceleration will be poor.
