I believe you need to have a read that this guy can fold one pair hands. If you believe he will fold solid top pair hands like AJ in this spot, then I think this is a +EV bluff.

Obviously if he folds hands like AJ this is +EV, that's stating the obvious.

The facter that determines the EV on this play is the players abiity to fold an ace not how often he has an ace. I didn't see it mentioned in OP. If that is obvious, my bad.
