DTC P0605: Engine Control Module

The ECM calculation function is malfunctioning. The ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (about 5 degrees) by the return spring. When the accelerator pedal depressed value reaches a throttle opening of 30 degrees or more, the throttle valve opens to a maximum of 20 degrees by the accelerator cable. Engine speed will not rise more than 2,500 RPM due to the fuel cut.
