Throttle position sensor
—
—
—
—
—
—
The ECM controls the electric throttle con-
trol actuator in regulating the throttle open-
ing 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 nor-
mal condition. So, the acceleration will be
poor.
NOTE:
If throttle position sensor 1 and 2 malfunc-
tion at the same time conducts following
control.
• ECM stops the electric throttle control ac-
tuator control, throttle valve is maintained
at a fixed opening (approx. 5 degrees) by
the return spring.

ECM controls the electric throttle control ac-
tuator by regulating the throttle opening to a
small range.
Therefore, acceleration will be poor.
