Lately i will be leaving from a parking lot and the Park and drive light from the instrumental cluster will be on in the same time, vsa light on, and check engine light, code is solenoid b circut low, and it appears that i go into limp home mode. Any ideas what could be wrong?

 

the check engine light is a clue,go get that code read from an auto parts store....
it will tell you whats wrong

 

But I forgot to mention, i turn it off it goes away, check engine light stays on, but goes away later, runs normal to

 

okay, it's still a clue, go get the code read...

 

Circuit fault indicates faulty solenoid, wiring or connector. Since problem resolves itself, it's an intermittent. Diagnostics w/ a VOM are necessary when problem is present.

good luck

 

Same thing happen to my 06 tsx. Bad alternator.
