• ECM illuminates oil pressure warning lamp on the combina-

tion meter.

• Engine speed will not rise more than 4,000rpm due to the 

fuel cut.

• Fail-safe is canceled when ignition switch OFF 

→ ON.

ECM controls the electric throttle control actuator by regulat-
ing the throttle opening to a small range.
Therefore, acceleration will be poor.

The ECM controls the electric throttle control actuator in reg-
ulating 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.
