Grand Caravan: Bought a "new" 2007 Dodge Grand Caravan. I received

Customer Question

Bought a "new" 2007 Dodge Grand Caravan. I received a P0441 on it soon after I bought it.
I tested for 5 volts by back pinning the connector and did not read anything. I replaced the NVLD and measured with the key off, still no 5 volts. I have not received the check engine light, but I think it is a matter of time.
I bought the 2 volume shop manual and do not see any good troubleshooting explanation of these circuits. The Internet is not the best resource either.
The manual shows the voltage is from the PCM. What should I do next? Is there logic that prevents the 5 volts from being generated?
When is the vacuum test run? It seems like it comes in after driving for an hour or so.
Where is the breather located? I want to make sure that is not clogged.
Thanks so much for your time. Have u thought about an online course for things like this?
Should I run a vacuum test next?
I do not want to send to a dealership and have them easter egg replacing parts.

Ran the vacuum test. Could not pull a vacuum on the system. I did read 5 volts on the NVLD switch with the iginition off and 10 volts with the ignition on. Probably need to run a smoke test...

A smoke test will probably help::
