2007 Greenline Errors P0A06 and P1A6E Help!

[bmetdave]

Hi,

I keep getting error codes P0A06 (believe this is aux electric water pump) and P1A6E (fail to restart). When codes register, Hybrid function disabled. First stop, engine restarts with normal starter instead of Motor/Generator, after that does not auto-stop. Have cleared codes once, they returned. My cheap code reader could not pick up. Went to Advance Auto and they read these codes. They said they were dealer specific. Would a failure of the pump disable the hybrid system? Need help please. Only 80K miles on this Vue.

Replaced aux water pump. Reset codes. Test drove yesterday: no codes, hybrid function working well, auto-stop working very well (even quieter than before; wondering if old pump had been binding when first starting). Tested old pump; will not rotate; bad. Incidentally, the pump is no longer available from GM and could not find PN with third parties. Website shows it would have cost $215. Found similar new pump on Ebay (GM 25774433) for $25. Swapped rubber mount from old pump to new. Bosch PN on plastic pump housing same between old and new; connector the same. Seems to work well. Will re-post if code comes back.
