Camshaft Position Sensor Passat

97 VW Passat VR6 auto

I got a DTC
16725 - Camshaft Position Sensor (G40): Implausible Signal
35-00 - -

I checked the voltage at the CMP (#1 and #3 pins) and got over the required
10 volts. I put in a new CMP sensor, cleared the code, ran the engine and
the code came back almost instantly. grrrr!
What else could be wrong?

Is there a way to read what the CMP is doing, or in this case not-doing,
using the Vag-Com?

TIA,
dave
