My van will not pass.

 

Did you recently reset all DTCs? This resets all monitors. The O2 heater monitoring should clear on the first drive. The evap system tests take multiple drive cycles and an overnight soak followed by a drive cycle that needs specific speeds and time ( not city driving).

I would investigate the O2 sensor first.

 

I bought a battery for the van. Now I just have to drive it. I mainly take short trips in stop and go traffic, in The City. I fully expect to resolve this in a year or two.

 

Disconnecting the battery must have reset the emissions monitors. Check their status periodically. The EVAP will be the last to clear. You may have to plan your driving if it does not clear in a month or two of normal drives.

 

Funny that you should say that. I've read that same thing over the years. But this time, it was the first thing to clear.

 

Seems like your O2 sensor problems are preventing the other tests from completing. I know the catalyst test needs O2 data.
EGR probably uses O2 also.

 

Thanks for your input. I appreciate that you're trying to help.

For Christmas, my pickup truck and van both got new batteries. I'm fairly certain that both of them just need to be driven. I live in The City. I only drive short distances.

 

The fuel system monitor completed today. 1 step closer .

 

I installed a new battery around Christmas Eve. With a battery disconnect, stored data is lost, and the car's computer has to relearn everything.



It's now February. I've been monitoring. And today, finally, the car's computer is satisfied with all of the sensor readings. According to the car's computer, I have only had 8 warm-ups, and 87 miles since that event. I was confident that the car was fine, the emissions system did not have any failures, and that it would eventually clear with enough driving. I can't even imagine how stressed somebody would be, if they had to pass a smog test. They could be out every day, with some sort of code reader, and trying to replicate all of those different driving conditions that are supposedly necessary to complete the Ford drive cycle.

 

And within a week, the F-150 also completed the drive cycle necessary. So for me, with my driving habits, it took about 6 weeks of driving for my Transit Connect and F-150 to be "emissions ready".

 

I thought that I could run FORScan, keep an eye on the monitors, and drive around trying to complete the drive cycle. For anyone else with the same idea......... good luck with trying to select the right Parameter IDs to look at. There are a lot of gauges available. I wasn't sure what to look at, or what any of the data actually meant.

 

It takes detailed knowledge of the different tests to effectively monitor them. The EVAP tests involve some purge valves and fuel tank pressure. You need to use the graph function to see when the valves change state and monitor fuel tank pressure and other parameters. It can be done, but it's not simple.

 

I got the notice to bring the van in for a smog check.

I knew that there was nothing wrong with the van.

Since I have a couple of different OBD II applications loaded onto different devices, I decided to run the I/M readiness test first. Just to make sure that there were no surprises when I got to the smog shop. The smog tech plugs the computer into the OBD II port, and it seems the same thing that you will see at home. There's really nothing the tech can do, to manipulate the test to pass or fail you. Not like the old days, where a crooked tech can play with the testing equipment, fail you, then charge you for a "repair". Smog checks today are very transparent.

















So off I went to the place with the lowest advertised price in my area.
