Display Group 09, Field 3, EVAP Control Solenoid Valve Duty Cycle

Duty cycle of 0 percent means valve is completely open. Duty cycle of 99 percent means valve is completely closed. During learning, valve is completely closed. Effects of EVAP canister purge on Oxygen Sensor (O2S) control will vary depending on EVAP control valve status (open or closed). To evaluate effects, compare difference between displayed values of O2S control while in both test modes (ENGINE BASIC SETTING and READING INDIVIDUAL MEASURING VALUES).
