PO 705 code on 06 jetta 1.8. Changed trans range selector

Customer Question

PO 705 code on 06 jetta 1.8. Changed trans range selector switch. No luck.
Car runs great, shifts great and shows zero symptoms of trans issues.
I clear the light but it comes back on after a couple of starts and my customer as well as myself are really frustrated. Again, this car operates beautifully

have you ohmed out the wiring, and checked it to make sure there is no mouse chewing or other damage?

Customer: replied 1 year ago.
Wiring is in mint condition.
I have not checked wiring with an ohm meter. The Trans shifts so nice I assumed wiring is good

It sounds like it is intermittent, but consistent enough that it sets the fault. It may be something as simple as spread contacts in the connector or something. I wonder if you should replace the wire ends to the connector, splice in new ones starting a few inches back?

It's not intermittent. If I clear the light while car is running, shut motor down and restart. Check engine light comes on.
I rechecked plug and wires. Pins and wires look great. Do you know what the voltage pattern should be at the plug ? I could check it with a probe meter.

it should just be a variable resistance in the range selector switch, which if it is new I would assume is OK.
