How to make the evap test run, and complete evap e40 readiness monitor?

[04colyZQ8]

I have efi, hpt, actron cp985o anyway to speed up the evap readiness monitor? Or what's the criteria to set it?

In the actron it says all the parts of the evap, test are ok and complete, except, it says low, on evap purge? -31. Is there a similar breakdown or monitor in efi scanner?

What year/model/vehicle do you have...?

Each readiness monitor has a list of associated DTC's each of which must not be set.

Ok, let me look up the list of DTC's associated with the EVAP test

( but you have a DTC set, so the readiness moniitor will say ready, but the test is failed. )

No no dtcs are set. Just in the actron monitor it says lo flow, but no dtcs are present

Does the Actron say it is low but withing range (i.e. in Mode 6)...?

[04colyZQ8]

Mode 6 yes, it says purge flow -36 lo, didn't say weather it's in range or not?

[joecar]

Mode 6 shows: high or low limit, the limit value, the test value, and units...

for example, it would show -36 lo and say a test value of -20, and units (say inH20/s or something)...
the -36 lo is the low limit, so the test value passes if it is above the low limit, and fails if below...
since -20 inH20/s is numerically above -36 inH20/s, then this test passes (and therefore does not trigger a DTC).

Oh, then all my evap, and purge individual settings say, ok, but the actual evap monitor says incomplete, I also selected run evap test, and it did not complete.

I read somewhere that the iat, and coolant temp need to be within 14 degrees of each other on cold startup, mine were 28 degrees apart? Maybe that's a problem. I changed from a e40 iat/maf to a ls7, I scaled the iat Using hpt, but maybe it's wrong?
