I believe you may be referring to Mode 1 PID 6. "shrft1" would be an abbreviation used by the software running on your scan tool or computer presumably to deal with limited area on the display.
Mode 1 PID 6 is commonly known as Short term fuel trim bank one. The short term trim indicates how much (as a percentage) the computer is enriching (positive values) or enleaning (negative values) the commanded fuel relative to how much it has recently (long term trim) needed in similar operating conditions.

If by "OBD" you mean on-board diagnostics (i.e., OBD II), the vehicle you describe probably does not have OBD II. OBD II became mandatory starting in 1996. If it does have OBD II, the location of the connector varies in Hondas. It might be near the hood release lever, or under the steering column, or even near the gear shift lever.
