2. The ECU can fully ground the solenoid (0 Volts) until it sees a high load signal (based on input from the Air Flow Sensor). It will then duty
cycle the solenoid from 0 to 14 Volts as long as the high load is present.
3. The ECU may fully ground the solenoid circuit (0 Volts) until a light load signal at high RPM (more than 188 Air Flow Hertz at 4500 RPM)
is found. It will then duty cycle the ground up to 14 Volts for a second or two. This will only happen in neutral and revving the engine or while
shifting gears.
