Can a S trap be converted to a P trap by adding a horizontal pipe in the "S"?

Question

Does adding a horizontal pipe, say 6in, in between the two S elbows convert a S-trap into a P-trap? Is it code?

See picture

Answer 1

If you add a vent at least two pipe diameters (4" since this is 2" pipe) away from the exit of the P-trap on the left, then it's to code.

If not, it's still an S trap.
