Failure Codes P0122 & P0222 on 2009 GTX 255 iS Limited

Recently with no motive Failure codes P0122 & P0222 prompted on the message display of a GTX 255 iS Limited 2009,after looking on the workshop manual, states those failure codes as TAS (throtle accelerator sensor) circuit shorted to ground ,I did all the checkings the manual describes ,bassically TAS resistance testing (was OK) and wires continuity (also OK,total continuity, no flaws at all) can somebody tell me what in heaven could be wrong?

I had a P0222 code on and off for almost a year, and then the TPS (or TAS in your case) completely failed. Just had it replaced last week. There was also an open in the main wire harness, causing the dealer to replace it as well.
