This is too much even for coincidence.
The new sensor came in today. Immediately I set up to test it on the 5v source for EGR (C1-48) from the ECM (pin C), ground (C1-61)(pin B) and signal (C1-73) (pin A). No voltage change on pin A with the flag using a pair of medium sized unplated channellock pliers as the target. Changed to the 12v lead from the ECM (C2-39). Flag gives change from 3.31 to 3.23V out. With the signal line disconnected it is 341 and 3.33.

Three different sensors ordered at three different times from 2 sources and they all test bad in the same way? I'm at a loss here. Anybody got any idea?

It's the tan sensor for the timing cover. Controller is 12200411, OS is Camaro.
