Evap System Readiness Monitor Incomplete
I recently repaired the Secondary Air Injection System on my 2006 Saturn Ion and erased all the codes and now all the I/M monitors have run and report OK except the "Evap System Monitor".
I have run at least 20 complete drive cycles totalling about 750 miles and no new codes have been posted by the ECM. However, the EVAP System Monitor is still incomplete.
What could be causing the Evap System I/M Monitor not to run. I suspect a temperature sensor but wouldn't I get a code that told me the temp sensor was defective?
Does anybody have any specific info on the test conditions for this specific
I/M monitor to run?
I have Delaware State Inspection due. They do not allow you to pass emissions with any readiness monitors incomplete. Thanks
