I kept getting the usual codes for the SAS (left and right bank) and it finally went away when I replaced the vehicles battery. It was bad and also the wrong type for the car. PO installed a 48R in place of the required 94R.

I installed the 94R (optional battery) which is what it must have for the Tip. Most of the Boxsters use the 48R which is marginal for our cars. Others have stated that 94R is the correct one to use as 2005MY and up use this as a standard. The two codes I used to get said it was to lean or low which dawned on me that the reference voltage was too low. This may seem to be your issue with a too low of a reference voltage. Either battery voltage or bad connection/ poor ground. Just a thought.
