2015 CT200H— came back from vacation to find dash lights on and staying on while car runs.

Any ideas?

Can anyone tell me where to locate the engine serial number? Can I see it without removing a whole bunch of stuff? Pictures would be great!

The pipe is sweating and dripping slowly as well but slower than the hose in the back of engine. What is it ? And is this normal?

*recently got a engine swap.

Anybody have experience with this issue? No check engine light, just the abs light and traction light turned on.

The sensor itself is working via a scan tool. Want to see if anyone has experience before throwing money at parts. Thanks!
