ES monitor test: How long to complete?

[davekro]

I've done two* complete drive cycles and the 'ES' icon for monitor test is still blinking on the OBDII.

1) Does this test need to complete before a Smog station will issue a Pass?
2) If so, what can I do to expedite this particular monitor test's completion?

Situation:
Even though emissions were within spec, Smog test issued a fail due to-
a) P0161 B2S2 O2 Sensor fail
b) old locking Gas Cap failed vacuum test.
I replaced the 02 sensor, then cleared the codes and that code has cleared (and test monitor completed). Days later, I installed a new locking gas cap, ran the first drive cycle. No codes present, but 'ES' monitor was blinking (I assume old failed gas cap caused this). I installed a new (non locking) gas cap and did *second drive cycle. "ES" still blinking.

3) Does a particular step of drive cycle complete the 'ES' (Evaporative System Monitor), or does this take 'x' amount of time?

1999 Savana 3500 box van, 55k mi on vehicle. 3k mi on new dealer installed crate engine.

Must have 15% - 75% gas in tank

OK, my gas tank has more than 3/4 tank so that is why the ES monitor has not cleared. But after I get it below 3/4 tank, does anyone know which of the drive cycle steps applies to the "ES" Evaporative System monitor? I'd like to focus on that step to get the ES Readiness Monitor to show ready (not blinking) so the smog station will test and pass it.

My gas cap had a pressure leak per the test station when it failed last time (as well as 02 sensor which was replaced and code has cleared).

Looks like it might be step 3, 4, or 5. It would be helpful to know which one to focus on.

To perform an OBDII Driving cycle do the following:

**Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 50°C (122°F) and within 6°C (11°F) of the ambient air temperature at startup. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run.

2) Idle. The engine must be run for two and a half minutes with the air conditioner on and rear defroster on. The more electrical load you can apply the better. This will test the O2 heater, Passive Air, Purge "No Flow", Misfire and if closed loop is achieved, Fuel Trim.

3) Accelerate. Turn off the air conditioner and all the other loads and apply half throttle until 88km/hr (55mph) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed.

4) Hold Steady Speed. Hold a steady speed of 88km/hr (55mph) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed.

5) Decelerate. Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 32km/hr (20 mph). During this time the EGR, Purge and Fuel Trim diagnostics will be performed.

6) Accelerate. Accelerate at 3/4 throttle until 88-96 km/hr (55-60mph). This will perform the same diagnostics as in step 3.

7) Hold Steady Speed. Hold a steady speed of 88km/hr (55mph) for five minutes. During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst.

8) Decelerate. This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.
