Had a P043E code - Evaporative Emission (EVAP) System Reference Orifice Flow Insufficient. Never did an overfill. After 3 or 4 days it cleared without the ICE running. The ICE had not run for maybe 4 weeks before the code showed up. I have not put gas in the car for the last 2 months.

Had made a dealer appointment but the code had cleared by the time I took it in. They found nothing wrong but found the code in history. I needed a NYS inspection. The inspection failed because the OBD was "not ready" and was told to run the ICE through some cycles and come back. The code had came on and cleared with out the ICE running.

When I got home I connected the ScanGauge II and at first it read "not ready" on the scan screen and shortly after it changed to "ready" which means at this point it is ready to pass emissions testing - the inspection.

So the question is: is it really "ready"? Can the OBD get to a "ready" state with out the ICE running through some cycles? It did cycle but on electric only. I need an expert to help out here!

According to posts in earlier threads the engine needs to run at least 100 miles including enough continuous use to get hot in order for the onboard systems to reset. If you search you should find those threads.

The P043E error may/can clear with out a 100 mile drive.

but as he said some flags need more gas miles.

Myself and others have seen this code pop up and then clear after a few days.

I have not added any gas in a year as I run 99.7 EV when I saw the error. I tried
(opened/closed the tank/added 1 gal gas/drive 3 miles on gas) error cleared a few days later.

Thanks everyone for their postings. I'm now attempting to have the car ready for inspection this Wed by running multiple cycles without charging as suggested. When the dealer failed the car after knowing about the cleared code and the code showing in history, he connected it to the NYS Inspection system and it had failed because is was not "ready". When I picked it up he had charged me $21 because it failed. I suggested maybe he first needed to verify that it was "ready" before he went through the start of the inspection. After pointing out that charging me $21 was BS, he told me to bring it back and there would be no charge for the inspection.

So the car has about 10 million lines of code but it can't tell me that all the sensors for passing an inspection have not yet been reset???

Read the readiness flags you mean?
Anyone with a professional grade scan tool certainly can...
