This provides a relatively smooth analog approximation to a variable value using an on-off solenoid and a digital output from the ECU. Digital outputs and simple solenoid air valves are much less expensive than analog alternatives and provide reasonable approximations. | This provides a relatively smooth analog approximation to a variable value using an on-off solenoid and a digital output from the ECU.
