Default Similar Problem - PO 725 Code on Altima

2006 Altima - 80,000 miles. Over the past 4 weeks while driving, I experience random/infrequent surges or slowdowns that feel like transmission slipping. Lasts only 2-3 seconds at a time - tach needle goes up or down - but car keeps going. 'Check engine' light came on yestrerday; local STS chain computer diagnostic: code PO725 (engine speed input circuit). Had extensive servicing 3 weeks ago (1st ever and nothing out of the ordinary for a car with 80k miles, incl. new battery). Can anyone advise how serious this problem is and what kind of repair is required/advised? Hate to admit, but I'm a chick who knows little about cars and would love advice from those who do before I subject myself to the Nissan dealer (ugh!) or local mechanic. (Knowledge is power ;-)
