ISC Duty Cycle

Scan Tool Range 20 percent to 40 percent: The ISC Duty Cycle parameter indicates the opening of the throttle valve by the ISC actuator in a measurement of a percentage. The ISC Duty Cycle percentage will increase when the PCM commands a larger throttle valve opening. The ISC Duty Cycle percentage will decrease when the ISC actuator responds to a PCM command for a smaller throttle valve opening.
