I have had that for a long time, doesn't seem critical (hope not). I have had to replace shift solenoids however, and there were no code displayed for that, perhaps covered up by the p056. Just a guess.

BTW, if your shift solenoids go, you will find yourself going down the highway in 2nd gear. Its a 'limp home' feature and is way better that a tow truck. The solenoid replacement is messy, tricky, documented in this form and do-able if one has some mechanical chops.

PO717 is the OBD-2 code for the same sensor. Here's a link to the FAQ section that shows how to perform this repair without removing the transaxle from the vehicle.
