CODES

2005 Nissan Maxima • 6 cylinder 2WD Automatic • 75,000 miles

2005 maxima won't shift past 3rd gear. R, 1, 2, and 3rd no problem. Local tranny shop ran diagnostic scan and threw codes:
P0726 - Engine Speed Input Circuit
P1726 - Electronic Throttle Control System
Where do I go from here. I'm a pretty good mechanic but not sure what parts need replaced.

Thanks
