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

cold start with fuel level between 15 and 85%.
idle in park (or neutral for manual) for 2 minutes with parking brake on and all accessories off.
accelerate at part throttle to 56 mph until you reach operating temp.
continue at 56 mph for 6 more minutes
drive between 45 and 55 mph for 2 minutes
stop for 2 minutes. if in drive, keep foot on brake. if in neutral with manual, keep clutch pedal and brake pressed.
turn off car for one hour.
turn on car and check I/M readiness.



Q: What's the difference between a bolt and a screw?
A: First, you screw. Then, you bolt.

Hi Golden CHicken,
The EVAP Syetem I/M Monitor finally ran today and posted an OK. I had run the drive cycle you mentioned about 20 times but was using the car every 12 hours or so for commuting. Then last Friday I searched a GM Cadillac website for their conditions assuming GM uses a similar ECM program for all their EVAP systems. The only difference was a 17 hour wait time followed by 6 more "drive cycles". The readiness monitor posted OK after the second drive cycle after I let the car sit untouched for 40 hours over the weekend.
I went and got my inspection done today and no sooner I went thru the lane the AC Compressor Clutch burned out. Go figure...

Is this the same for the Redlines as well?

I need to get my car inspected ASAP but it is taking forever to ready the evap and catalyst.

Can you force them to ready?

you might be able to force it to run the test, but you probably can't force it to show ready

You can actually force all ready's besides evap one so that would be enough to pass. Just disable the codes and you will be set, but if your car looks like it should fail like you have no exhaust and they try resetting the battery and you pass. They will fail you for tampering with emissions.
