Hey guys, having some trouble with my 911 hope you guys can help out

I have a 991.1 Turbo S and I’m having a shop install a Dodson Clutch. Whats happening though is after install the PDK will not calibrate and im getting a few codes for pressure sensors. The codes are

POB41
Pressure sensor1 (clutch 1), signal implausible (Signal error)



P0846


Pressure sensor 2 (clutch 2). signal implausible (Signal error)



P1775
Protective measures cannot be performed (No fault symptom)



7101A

Pressure sensor 1/2 - signal implausible (No fault symptom)



P1870

PDK control unit - incorrect calibration (No fault symptom)

After installing all new pressure sensors It threw a different code right away for pressure sensor 1. Took it back apart, swapped the original pressure 1 back in because that didn’t give us a fault originally we were only replacing it as a precaution and the same pressure sensor 1 fault is there.

Have any of you ever dealt with this on a pdk? Any suggestions?

 

Someone much better versed than me suggested this may be a harness/connection concern since the sensors don't fail all that often. Electrical gremlins are insidious bastards.
