Fail-Safe Mode

WARNING: This page is about a different car, the 2005 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.

When the malfunction is detected, the ECM enters fail-safe mode and the MIL lights up.

FAIL-SAFE MODE TABLE

Engine operation condition in fail-safe mode
The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10 degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal condition. So, the acceleration will be poor.
