Change oil and filter today and now have a code 20 checked the air sensor connnection dont see any broken wires Is there an OHM reading for the sensor or is there something else I should look for?

I had the exact same problem after an oil change it was a corroded splice in the wiring harness. It is the two black dots on the diagram In the black/blue or the blue wires. This is the little black splices shown in the photo. You can use a multi meter to test from the splice to the white connector. Basically I ended up cutting off the splice connectors and soldering them.
