I'm a mechanic, just can't find any repair info, Mitchell or Alldata. Know it's right/rear solenoid #2, just don't want to shotgun the hydraulic unit, would be nice to diag it. Any help?
Expert:  Ron replied 12 months ago.
Are you sure of this code, there is no reference to it which usually means its not a valid fault code. Can you recheck it?
Customer: replied 12 months ago.
Positive! Can you find any codes for the description? Right rear solenoid # ***** malfunction?
Customer: replied 12 months ago.
If you Google it, the description and code come up. Others are having the same problem. Are you a factory tech or generic, looking at generic info? Mitchell, Alldata, etc..?
Expert:  Ron replied 12 months ago.
No unfortunately Im not finding any reference to this code even with GM. Ill open the post back up for you and see if someone else has something to offer.

PCU likely means powertrain control unit. This means your code is actually a P0123. This code sets when the throttle position sensor voltage goes too high. This can happen for two reasons.1) Break in ground circuit to sensor. Check the black wire to the tps for any breaks and verify that you have a good ground at the connector.2) Bad sensor. If the ground circuit is okay, replace the throttle position sensor.

it is C0095. Not sure where pcu0123 came from. Ron tried to help but couldn't. I contacted the dealership and they are the only ones with access to this code. Thanks for trying to help. Peace out!
