2001 sable not starting when tps is connected

What is your question?

I have a 2001 mercury Sable. Two weeks ago, due to vehicle running rough, I change out the TPS and cleaned the IAT. The vehicle has not started since. After ensuring I had spark and fuel, I decided to check the repairs I did earlier. I unplugged the TPS connector and the vehicle started. When I re-plugged the connector, I received a PO122. I have changed that sensor to have the same problem where the vehicle will start if unplugged. What is the calibration procedure for the sensor? Is there a short in the circuit sensor? Not quite sure how to check that for now…..still researching.

What makes this problem better or worse?

disconnecting tps starts. vehicle will not start if connect
