Purge Monitor

The Purge Free cells must be updated before the monitor will run. The enabling conditions are similar to the O2 Sensor Monitor enabling conditions such as, the vehicle will need to be driven for a period of time at highway speeds and brought to a complete stop. The Purge Flow Monitor will attempt to run every OTHER throttle closure. If all of the parameters are met and it still does not run, with your foot firmly on the Brake, quickly open and close the throttle, this will allow another Purge Free update, and then the Purge Flow Monitor should run.
