There is.
Your PCM defaults to normal mode for a NA car in Performance mode.
Your PCM retards the shifts in economy mode by inducing a resistance (voltage divider circuit to drop the voltage from 5V at the PCM to 2.5V) in order to slightly retard the shift points for greater economy.
I have personally never seen a resistor short across the leads, so I'd say you have a short to ground holding that pin at a constant 5v and preventing the resistor from being introduced into the circuit.
