2002 Autel Code 2B Vapor generation max absolute pressure rise Failed

[whrbbt]

After leaving my Bird parked for a year, I put in a new battery and it started fine. After driving it for approx 100 miles the CEL - check engine light came on.
(solid light not flashing).
I didn't notice any issues with acceleration/revs/idling.
The next day I drove it another 140 miles with no noticeable engine problems.
Using an autel scanner today I got the following error code - $2B 2B Vapor generation max absolute pressure rise Failed
with reading Min 1245.44 Value -15692.60 PA

The vehicle is currently located in San Francisco and booked in to a shop on Wednesday but I would like a sense of what might be wrong.
I plan to drive it to Irvine on the weekend and would prefer to have any work needed done down here, but def don't want to risk 400 miles if the engine might cease.

I previously had a new fuel pump installed just before I parked it for a year.

Update! After posting this I used the Autel maxiAP AP200C code reader and scanner tool to reset the codes. The check engine light went off.
After driving the car from SF to LA the check engine light remained off.
Last week I had a smog done and it passed.
I haven't checked the codes again, I will do that to see if the error code is still there and will post results.
