Throttle position Sensor

--

x

--

--

--

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.

  • Engine speed will not rise more than 4, 000 RPM due to the fuel cut.
  • Fail-safe is canceled when ignition switch OFF → ON.
