Ebay MPXV7002 fault

Last week I purchased a MPXV7002DP air pressure sender from ebay for $14.
It did not work... It always showed 4.99 volts output and not ratio-metric centered at 2.5 volts. Someone has forgotten to ground pin 3 of the MPX.
Close inspection of the Ebay pictures of this and other sites shows a small plate through on the bottom of the PCB. The one i have does not even have a trace from pin 3.

The above photo is of what i think are the newer boards that should have pin 3 grounded via the plate through seen in the yellow area..

The easy fix for my unit is to scrape a little paint from the ground plane next to pin 3 and bridge it with solder. Red arrow below.

Location of my solder bridge to ground.

It works perfectly now.
I have notified the seller. Lets see what they say.
